Stadank0, 3 January 2018Hi all, My name is Frank and I am a client of Stuart's. I'm currently in the treatment stage of the CR in what has turned out be an amazing project IMHO...The studio…
Soundman2020, 3 January 2018I should add that Frank has built this place from the ground up, and done the majority of the work himself, which is pretty amazing. To get some perspective on what he's…
Stadank0, 3 January 2018From the man himself! Thanks for the kind words Stuart.....I should repay the compliment by saying that Stuart has proven to be very bright and generous with his…
Stadank0, 6 January 2018Hi Stuart Done as much as I can with the ceiling. Going to need the bass trap detail so I can move forward on the ceiling and back walls. I can start on the soffits if…
Stadank0, 6 January 2018Hi Stuart, After reviewing the dims for the new speakers, I discovered that I'm going to need to lower the speaker platforms about 3.5", otherwise the tweeters will be…
Stadank0, 7 January 2018Hi Greg, I fixed the first 3 you mentioned. I went with the Focal Trio monitors. I have the Focal Twins in at the workstation in the LR. The bottom picture is the way…
Soundman2020, 7 January 2018Frank, I'd hold off a little on redoing the soffits: I know it looks easy in the SKP, but there's a lot more to it than meets the eye! I'd also like to do some other…
Soundman2020, 19 January 2018Yup! Update for the folks following this thread: Frank is now valiantly building some rather complex stuff I designed for him, for the rear corner of the room. We did a…
Stadank0, 19 January 2018The title seems appropriate... :thu: Thanks for posting that Stuart... 8) you saved me the trouble and right about now I'm covered in damp sawdust from dealing with…
Stadank0, 22 January 2018He had me put a small 1/2" thick bit insulation up against the posts, I used a shred of pink fluffy. Also a 1" piece of 703 against the back wall and 1/2 of the floor.…
Soundman2020, 22 January 2018There's a thin layer of light insulation right up against the rear of the "slats" (which are actually trimmed-down 4x4's), and there's also a thin layer of of 703 up…
Soundman2020, 22 January 2018They would have gone into the slots, but there's no need for that, as far as I can see. Your measurements are within spec, and in fact having the posts slightly narrower…

Soundman2020, 22 January 2018:thu: There's also the issue of being careful to use the right equation! There's actually a wrong version of the Helmholtz equation circulating, and it has even been…
Stadank0, 26 January 2018Here's the Bass Trap... A lot of work... Fortunately Stuart is pleased with the results... :mrgreen: I'm sure he'll be commenting soon. Very encouraged! Image not…
Soundman2020, 26 January 2018Update on what all of Frank's hard work actually accomplished. It's rather nice, actually. So here's some pairs of "before" and "after" graphs from acoustic measurements…
Soundman2020, 29 January 2018Right. Right. Prediction will get you close, especially for a rectangular room, but this room is not rectangular: it is closer to square (it has to be: it's a "corner…
Soundman2020, 29 January 2018Frank has put the insulation on the ceiling, and sent me his latest REW measurements, so here's some more "before" and "after" pairs, where "before" is with just the…
Stadank0, 29 January 2018I'm guessing ill only need to do the half of the ceiling that won't be behind the cloud. I do need to put in a correction in there....The insulation in the ceiling…
Soundman2020, 30 January 2018Even more impressive! Four and a half inches of typical insulation is giving you some pretty substantial improvements! 4.5" is 3.9% of the 113Hz wavelength, 2.8% of the…
Stadank0, 1 February 2018OK, So here are some pics of the back walls insulated with panels on them. Nothing exciting to see, but they are now crushing the decay so I'm sure changes will be made.…
Stadank0, 2 February 2018To be on the safe side I went back and did a measurement without the covers on. very little change but wanted to eliminate any suspicions all the same. I'll let Stuart…
Stadank0, 3 February 2018So after looking at the results of these measurements and nothing better to do until I hear back from Stuart, I have a theory... There is now a significant dip at around…
Soundman2020, 3 February 2018It might have been there before, just masked by NOT having all that absorption around: In other words, the absorption trimmed the long grass way down, so now you can see…
Stadank0, 3 February 2018I'm on it! will report back soon with results... Things are definitely progressing in a hopeful way. I started this project with home studio ambitions but those have…
Stadank0, 3 February 2018i knooooooowww...if only!! I never would have guessed back then, I can tell you that. :lol: In all reality, I still believe that the quality of work done in this space…

Soundman2020, 5 February 2018:shock: :o I hope you made it through that without too many broken bones! :) Anyway, I analyzed your data, and it seems you only had one plywood panel on hand, which you…
Stadank0, 5 February 2018I sent the new mdat file! :thu: So the (plywood test center) is 1 sheet on each wall and the last one un-named is the 2 sheets on each wall... I've been mountain biking…
Soundman2020, 5 February 2018I have taken a better look, and it's nice. Well, it's ugly, actually, but it's what I expected, so that's nice! It's more like: "The Good, the Bad, and the Ugly"! The…
Soundman2020, 6 February 2018Got it! It's working, and at the correct frequencies, but not enough yet: Image not preserved: Frank-REW-RT---1-mil-and-6-mil-plastic-strips--initial.png You can see…
Soundman2020, 6 February 2018Frank OK'd sharing some more details of the design, so here goes: Right. It's mainly a poly-cylindrical diffuser, with a broad curve, designed to deal with low…
Soundman2020, 6 February 2018At 19" along the two 90° sides, it isn't exactly small! Nearly 16" deep in the middle (tip of rear corner to front face). Don't forget there's stud framing behind that,…
Stadank0, 6 February 2018OK second test results sent to you Stuart! So what I did, was put the plastic over the covers to test because they were already up and they hold the 1" duct liner. The…
Gregwor, 6 February 2018This is the best thread on the forum! I hope I'm not hijacking this thread. It is directly related to CR treatment, Helmholtz, and my question is stemmed from a comment…
Soundman2020, 7 February 2018I'm working on slats for the rear center section right now... should be ready a bit later today. Better go buy yourself lots of 3/4" or 1" thick wood, in planks many…
Stadank0, 7 February 2018Hmmmm. not sure yet on the style. probably gonna go with common pine lumber cause its cheap and I can either stain it or paint it. I think I'll have a better idea when I…
Soundman2020, 7 February 2018OK, here's the plan. This is just for the rear corner part, not the walls (yet). We'll so how it goes with this, then decide on what to do with the sides. Image not…
Stadank0, 7 February 2018OK! So I will tack everything up in a temporary fashion. I'll do the phases of testing as suggested. You may want to go back and look at my post with panel pictures. I…
Stadank0, 9 February 2018Alright...Here is the next test process. I have temporarily installed the slats and done three tests according to your instructions Stuart. New mdat also sent of course.…

Soundman2020, 10 February 2018It would be good if you start posting your initial designs in your thread, so we can get an idea of where are right now, and where you want to go. Sometimes it-s good to…
Soundman2020, 10 February 2018We are getting too many specular reflections like this, with those flat planks, so I'm thinking of taking this in an entirely new direction.... if you are up for it! :)…
Stadank0, 10 February 2018So I would have to round off the faces of each board? I'm guessing the only way I could do that is by sanding..That sounds painstakingly horrible. I'll have to figure…
Soundman2020, 10 February 2018It's MUCH easier with a router! :) Image not preserved: half-round-router-bit-SML-ENH.jpg Image not preserved: half-round-plank-end-bull-nose-SML.jpg Use a half-round…
Stadank0, 10 February 2018Of course, what was I thinking...I tell ya...first glance and all.Should have thought of that. :roll: So embarrassing :oops: :) Still, if we can work with 1x2's that…
Stadank0, 10 February 2018YEs, 3/4 x 1 1/2 actual. Always annoys me that the industry adopted that standard...can't call things what they are :roll: Awesome though! I think we're already getting…
Stadank0, 13 February 2018If it saves you time I probably only need the layout line for the curve of the wall... I'll have to trace that and cut it and shape it to make the ribs which will be the…
Soundman2020, 13 February 2018It's a bit more complex than that: I've gone through probably a dozen curves with different slat sizes and spacings, trying to get this to work out both acoustically and…
Stadank0, 13 February 2018Well that is an occupational hazard of being in uncharted territory... I know this will have to be sorted and that will take some time. In all fairness though, my studio…
Soundman2020, 14 February 2018I think I have a workable solution for you. I'm not 100% happy with the looks, but I'll eave that judgement up to you... OK, no soffit! No problem. Just floor to ceiling…
Stadank0, 14 February 2018I don't find it to be ugly...its mostly the feeling of space I care about. I'd like to go as flat as possible without mooting the point of it. I'm guessing you mean that…
Stadank0, 14 February 2018I did just talk to a guy that said that they would rip 2x6 lumber down to 1x6 for me... its standard doug fir..Probably not as pretty but I can paint it.. I'm tempted to…
Soundman2020, 15 February 2018:yahoo: :thu: Right! That's why I wanted to use smaller slats, as they look less imposing and give a more airy, spacey feel, but they just don't cut it, acoustically.…
Stadank0, 15 February 2018I'd love to see your desk idea. I'm not going with a full blown console, I'll be mixing in the DAW. I will need desk space for a controller. Ultimately, I don't see the…
Gregwor, 15 February 2018Stuart, What is your reasoning behind embedding the CR glass so far into the front wall? To maintain a certain resonant frequency within that cavity? I will have about a…

Soundman2020, 15 February 2018Mostly room volume. Recommended minimum volume for a critical listening room is 1400 cubic feet. Frank's room is 1380 cubic feet, which is fine but on the edge. If I…
Soundman2020, 15 February 2018It's the Sterling E series desk that I'm thinking of as the concept. Here's the actual desk inserted in your room: Image not preserved:…
Stadank0, 15 February 2018Yeah, I definitely want to build my own desk. Furniture is insanely expensive!!! That desk is $4000 US at Sweetwater! I could never :ahh: ..Too many other things worth…
Stadank0, 15 February 2018Are we set back quite a bit on time? I know you have other stuff going on in March. Not freaking out...just a bit of a surprise....If possible, I'd like to get a general…
Soundman2020, 15 February 2018Yup... I did mention it was a bit more than a speeding fine! (Unless you are doing 500 MPH in a school zone, maybe.... ) I just remembered that I did a "reduced size"…
Soundman2020, 16 February 2018Final (hopefully) entire real wall. Ceiling soffits added above 8' slotted polys, hump reduced to 7 1/4" inches, my small mastering desk, electric outlets on rear wall…
Stadank0, 16 February 2018How critical is the curve accuracy? I have enough information for the high point but there is no contour dimension info. Might be easiest to get me the .skp..Not sure…
Soundman2020, 16 February 2018I realized that the dimensioned view probably wasn't too clear, so I did another one: Image not preserved:…
Stadank0, 16 February 2018(That looks like the same screenshot)Unfortunately, I have no bearing on the curve itself..Its free hand for me at this point. I have no way to lay that out with any…
Soundman2020, 18 February 2018Afraid not. Not for this case. Higher density would be better, in this specific case, which is why I suggested OC705, if you can get it. But 703 is also OK. We can use…
Soundman2020, 18 February 2018:thu: That's fine, but not so good in the lows (to be expected: it's only 1" thick). So I'd recommend the following "fill" for the soffits above the poly's: Starting…

Soundman2020, 21 February 2018Pine is fine, as long as it is good quality, fully dried, and won't warp in the future. I prefer MDF for this type of shaper rib, since it will keep it's shape over time…
Soundman2020, 21 February 2018Cool! I'd suggest that you start at the middle and work outwards with the slats. So put up the first three slats on each side closest to the middle of the rear wall, REW…
Stadank0, 22 February 2018So now that you've created 18 separate compartments, do they need to be sealed from each other? Also, How exact do the vertical separator locations need to be? Still…
Stadank0, 22 February 2018From all of my research, nobody out there directly addresses the concept of out dusting with regards to fabric marketing. I've come across several forum threads asking…
Stadank0, 23 February 2018Alright then....More wrenches in the plan albeit minor ones.... The vents are hitting the soffit frames a bit. Gonna have to finish the trim around the vents and put the…
Soundman2020, 23 February 2018Strange! I adjusted that carefully, many times over, precisely so that would not happen. Maybe your silencer boxes are a bit off from the plans? Can you adjust the…
Stadank0, 23 February 2018LOL... the design world is definitely cosier... I'm just going to do some cut outs on the top board to fit... I don't feel like going back and redoing any of the work…
Stadank0, 26 February 2018I don't know that rigid insulation would be a bad thing...just doesn't seem cost effective at least here in the states. Is your concern isolation related? Is so, then…
Soundman2020, 26 February 2018Then it isn't an analogue of 703! :) Beware when companies try to sell you acoustic products that are "just the same as X, but much cheaper"! That's like someone trying…
Soundman2020, 26 February 2018Do you have a link to that? I'd like to see it... Also, density is not really the issue. What matters is something called "Gas Flow Resistivity", which is measured in…

Stadank0, 27 February 2018There's just no way I know all that!!! :lol: Love to learn though...Didn't get much done this weekend due to other life issues. Oh well. Marching on! Here are the…
Stadank0, 28 February 2018Got one soffit installed and will finish the other one tomorrow.. Rain coming later in the day tomorrow and not letting up for maybe 2 weeks. Super bummed.. Finish work…
Stadank0, 1 March 2018Hi Stuart, I'm trapped under bad weather for the moment, which will slow me down on finishing the back walls for a week or so. I need the outdoors for the sanding and…
Stadank0, 9 March 2018Not too exciting, but though I'd better post something before the thread goes stale! gonna do a 3 tone scheme with the boards. They will have a dark cappuccino stained…
Stadank0, 13 March 2018The finished boards....Weather got me again. Still need to do some more sanding on some of the ribs. Install will only take about 2 days after that. Stuart, I picked a…
Soundman2020, 13 March 2018Slats are looking good! :thu: Ummm... are you SURE you got the right thing? This one? https://bssaudio.com/en/products/blu-102 That's the only "Soundweb BSS Blu-102"…
Stadank0, 13 March 2018Actually the Blu-50 was the recommended unit. I bought the 102 after using a comparison chart. I sent you a PM to go into more detail... The 102 has all of the audio…
Stadank0, 21 March 2018Hi Stuart, I have an issue with the upper row space on the left side. Looks like a combination of issues with the soffit box are causing the gap to dip to 13.50". Its…
Soundman2020, 22 March 2018Good to see the progress, Frank! Glad the weather (and the cat!) is finally cooperating. I'm not sure if I understood the first part of your dilemma correctly; Is the…
Stadank0, 25 March 2018Well, Now I did it!..I went and installed all of the deep vertical dividers at 17" from the end instead of 16". I decided to make the ribs an inch shorter to get rid of…

Page 8

Soundman2020, 25 March 2018Ooops! Not so good... Let me think about that a bit, and re-do some of the calculations. The main issue here is that the vertical dividers will no longer fall in the…
Stadank0, 11 April 2018Back at ti again. Sorry for the long break! Doing some testing with Stuart to make sure that I have it right before I commit to closing things up. Image not preserved:…

Page 9

Soundman2020, 27 April 2018And the results of Frank's hard work are in! . . . OK, I'll do this in sets of three graphs. Each set of three shows first the original empty, untreated room. Then the…
Stadank0, 4 May 2018Hey man!!! The point of these pictures is to show all the brilliance while hiding the flaws! :finger: OK...I've been dying to use that emoji. This as close a I've come…
Soundman2020, 5 May 2018Well, the digital tuning part will be "easy" from your end! Not so much from my end... so the tables will be turned there, at least. Yup. Reduces the need for cooling a…

Page 10

Stadank0, 15 June 2018man you are on top of that stuff! Good on ya! :lol: Whenever I read your posts, I see you chasing down those bad guys. Almost seems like a passion for ya. Alright, so…
Stadank0, 28 June 2018Hi Stuart, I've got the modified framing done. The question is, do I do the Enclosure boxes next? It would be easier for testing to have the side panel completely out of…
Soundman2020, 28 June 2018Cool! Frank's back! :yahoo: Yes, let's leave off the side panels until as far as possible down the line, to simplify the speaker mounting / adjusting. So next up:…
Stadank0, 28 June 2018Thanks all. I'm definitely back and will be for the rest of this build. To answer your question Greg, I gotta think about that. Probably the best thing will be to mount…
Soundman2020, 28 June 2018Not sure if you remember, Frank, but when I sent the dimensions for the soffits, there were a couple of images about the amps. Here's some close-ups, without the…
Stadank0, 28 June 2018I did see that in the model but thought it was kind of a suggestion. Good point on the heat affect. I wasn't planning on putting the amps under the speakers. Moreover, I…
Soundman2020, 28 June 2018Not a problem: You have that large vent "chimney" up through the entire soffit, directly behind the speaker, and your HVAC intake is right above that (the very reason I…
Soundman2020, 28 June 2018If you really want to go for "maximum awesome", then sure! Let's add subs. By all means. However, those Focal's do go all the way down to 35 Hz all by themselves (in…
Stadank0, 28 June 2018Cool. I love them too. They're awesome! Certainly a flavor I can live for rest of my life, if I can keep them going that long. :D I already have 2 Tannoy Ts10 subs…
Soundman2020, 28 June 2018Interesting! I guess they must have changed something that lightened them up quite a bit, but then didn't update the manual. I've seen that before, so it's not all that…
Stadank0, 28 June 2018I wouldn't want to work with the bottom ones because the shelves are going to be going in and out a few times with the speakers probably. I've got to make some extension…
Soundman2020, 28 June 2018Right! I forgot to mention that. You can leave a large gap at the top, just under the window sill shelf. Maybe 2 or 3 inches high. Hold the rest in place however you…

Page 11

Soundman2020, 29 June 2018I don't recall off hand, but is that a wood panel, or a metal panel? Aluminium? If aluminium, you can probably get a piece of scrap some place that works in aluminium.…
Stadank0, 30 June 2018That is cool, Although I imagine the total number of people to be lower based on how many times people repetitiously visit the thread. :-P Its fun to know that people…
Soundman2020, 4 July 2018They shouldn't. I probably forgot to update something. The ones in the shelf under the speaker and the top of the soffit enclosure should be the same size as each other,…
Stadank0, 4 July 2018Thanks. Just wanted to make sure there is no tuning of any kind involved with the structure. No need for you to be too bothered. I can interpolate what I got. I'll just…
Soundman2020, 4 July 2018I would prefer to keep it it pretty much as is. Making bigger slots in the top and bottom might weaken them too much, and there's quite a bit of stress on the top panel…
Soundman2020, 12 July 2018Let me just double-check the dimensions of the enclosure boxes, and I'll get back to you. To do that, please confirm what type and thickness Sorbothane sheets you…

Soundman2020, 13 July 2018Do one test (set of 3) with the mic in its original location, same as always, then another set of 3 with the mic in the new location, so I can compare and have a future…
Soundman2020, 14 July 2018:thu: I need some input: I was just doing a final double-check on the enclosure box dimensions, and noticed that the published dimensions for the height of your speakers…

Page 13

Soundman2020, 17 July 2018Yesterday was a public holiday where I live, so this has been a nice long weekend for us! Sorry: I should have warned you about that in advance... The good news is that…
Stadank0, 17 July 2018I have a belt sander, but I think what I'll do is cut everything close to dimension within 1/8". Then do a finish cut. Should work fine. Actually I'd probably be safer…
Soundman2020, 17 July 2018Check the server directory: I just uploaded a bunch of images with the dimensions for the enclosure box. Take a look to see if it's all clear, and I'll get back to you…
Stadank0, 1 August 2018Well it would have been if it didn't have to be 1/32" accuracy and I had a better saw, that's for sure :jammin: I'm running into squaring issues. Think I can manage…
Stadank0, 1 August 2018Gonna try a dark stain (Espresso) that I've used throughout the studio already. Its the same stuff that's on the tops of the slats on the back walls. Gonna be maple…
Soundman2020, 2 August 2018It's not critical. Measure 3/4" in from the inside face of each side panel, and that should give you a slot 11 1/32 wide. But like I say, it's not a critical dimension:…

Page 14

Soundman2020, 8 August 2018Cool! For anyone following the thread and not having a clue what is going on with the above cryptic conversation: Frank ran into an issue cutting the Sorbothane for…
Soundman2020, 10 August 2018Hey Greg. Sorry I missed your post: The actual equations are on their website. You can download the engineering design guide in PDF, and they are on the first few pages,…
Soundman2020, 12 August 2018Update! Frank has assembled his speaker enclosure boxes with the speakers inside them, and they worked out great! We had to adjust some of the mounting process, because…
Stadank0, 15 August 2018On another note.....I'm looking at the desk and wondering if I can make it bigger? I would follow the outline of the room of course. I could conceivably add more surface…
Soundman2020, 15 August 2018You could make the desk a little larger out to the sides, yes (extending the "wings" a bit) without too much acoustic penalty, but it might start getting in the way of…
Stadank0, 15 August 2018Cool, I want as much desktop as I can get. I was also looking at ways to get increased rack space as time goes on. Not needing to add it right away, but having the…
Soundman2020, 15 August 2018Also, this might be interesting for some people, regarding the importance of correctly and accurately positioning your speakers and mix position, and also the…
Soundman2020, 17 August 2018Success! Frank has just completed the very successful "floating" of his speakers in the soffits! They are now sitting happily in there, fully decoupled from the…

Soundman2020, 24 August 2018Both baffles are up, and there's some new REW data, for those interested in understanding what baffles do, and how the room is progressing with that, acoustically.…
Stadank0, 29 August 2018So here is the rough cut of my desk for testing purposes. This will prove to be the final tug of war between Acoustic Engineer and Sound Engineer... :cen: Form vs.…
Stadank0, 31 August 2018Well....Initial desk testing is not yielding good results. looks like I'm stuck on that until we get the cloud and the rest of the treatment done. Bummer... :( If Stuart…
Stadank0, 31 August 2018I'm confused....The picture shows 3" of rigid...That's what I'm asking about. I can't get rigid insulation till Tuesday next week. Wanting to know if it has to be rigid,…
Soundman2020, 3 September 2018Looks like it should be OK, but do round the edges that face towards the speaker itself: Sharp edges are sources of edge diffraction. OK, yes, that trim is a long way…
Stadank0, 3 September 2018Hi Jakob, If anyone can bring out the best in your space, its Stuart. Your in good hands no doubt...Thanks for the kind words also. Its by far the hardest thing I've…
Stadank0, 3 September 2018That nasty router incident was really an issue of trying to use a shank that was just too small a diameter for the job of cutting a 2" depth. Also, the cutter was…
Stadank0, 3 September 2018Hi Stuart, At this point I'll just pick up some 703 tomorrow and also buy what I can for what we know. I know I can get 703 all day probably faced as well. I'll have to…
Stadank0, 3 September 2018Actually I think I answered my own question. According to the data sheet, 703 2" FRK has a coefficient of .63 down at 125 Hz...So, I can use some combination of 703 FRK…
Soundman2020, 3 September 2018:thu: Yup! Get the 2" 703 FRK for the underside of the cloud, and get some 1" 'whatever' (not critical, but not too dense) for above that, to make up the 3". For the…
Stadank0, 3 September 2018Sounds good....Yeah I had the mods in mind. Shouldn't be a major difference fortunately. I'll just use my screw and fender washer technique for retaining the rigid…

Soundman2020, 4 September 2018Unfortunately, yes you do need it. That cloud is designed as "hard backed", because it needs to deal with some modal and SBIR issues in the vertical plane. The only way…
Stadank0, 4 September 2018Oh Yeah, I'm not too freaked out, Just looking for any advantage I can get when it comes down to it. You know I'll figure it out. I raised that entire ceiling and HVAC…
Soundman2020, 5 September 2018You can if you want, but only one, and don't make it very wide: I don't want to lose too much slot area. But those slats are really thick! An inch and a half! I don't…
Stadank0, 5 September 2018Today's episode! Got a lot done...Spent the 3 hours getting the insulation..Traffic's always bad on that route. Got the framing and caulking done, insulation installed…
Soundman2020, 5 September 2018Looking good, Frank! Nice workmanship, as usual! One more point: It's important that the FRONT layer of insulation (the very light-weight, soft, low density stuff) must…
Stadank0, 6 September 2018Alright Y'alls! Here's the door slats done without trim of course....This conglomeration will get much prettier soon with trim..I don't think Stuart can fit in any more…
Soundman2020, 7 September 2018Well, dammit Frank! You've gone and made me a liar! Before you did this, I warned you that the results would not be major. And it turns out that it isn't working the way…
Soundman2020, 7 September 2018Ahh, what the hell.... let's add a couple more, to give Frank some bragging rights here. It's generally accepted that a home studio where the overall frequency response…
Stadank0, 7 September 2018Seems I may be setting the bar high for future do-it-yourselfers such as myself! :mrgreen: Not to worry, John's latest presentation from Taiwan will forever keep me…
Soundman2020, 7 September 2018That's music to my ears! Squiggles on a graph are one thing, but actual human ears listening to real music are another. If it is meeting your expectations, then all is…
Stadank0, 7 September 2018I know I'm the only one hearing it with my own ears with regards to the forum, but when you consider how that room sounded untreated...Yeah, its come a long way. The…

Stadank0, 19 September 2018Thanks Pal! :mrgreen: There's a reason I've been mentally blocking the electronic side of things(including cabling). Its always a can-o-worms!.... Just took a serious…
Stadank0, 25 September 2018Popping holes in walls today. Progress marches on! In the meantime here is a simple track I made to stress my cables. And maybe I had some fun while I was at…
Stadank0, 27 September 2018well, Thought I had it, then I didn't! Some of the cables are a few feet too short.....Gonna have to wait for couplers and extensions to show up on Friday then test it…
Stadank0, 11 October 2018Alright the trim is done and we are on the cloud!...That should go quick compared to the dreaded trim.. :shock: I hate trim !!!!! no fun... Stuart, in case I have…
Stadank0, 12 October 2018Almost done with the placement....just need to set the front anchors. This is bar far the hardest part....the rest will be cake in comparison. Its impossible for me to…
Stadank0, 16 October 2018Got the final placement of the framing done. A couple of sticks to throw in on the ground still, then the hard back and the light bay. The sides do fan out a bit over…

Stadank0, 22 October 2018This part sucked....Had to stop at one point because the drill started smoking! And Yes Stuart, I got the layout wrong on the upper left side.(picture orientation) Also…
Stadank0, 23 October 2018Well I finally finished the building electrical! Been at it all day again....Lighting came out amazing :yahoo: Lots of mood options with regular light as well. Will have…
Stadank0, 23 October 2018Thanks man....I'll probably invest in some better quality led strips in the future. These are not totally consistent in tone. They'll work for now. But yeah, it came out…
Soundman2020, 24 October 2018Been kinda busy today! Sorry about that. But yeah, the REW data is looking rather nice, with some caveats. Overall, a nice improvement. First, however, there seems to be…
Stadank0, 24 October 2018Well, I did a nose level test with the sheet rock lift..check email. Looks like 91" is the sweet spot for spl, but I think we're stuck with the phase flip, at least in…
Soundman2020, 25 October 2018Try this: Tilt the cloud down 4° more, which puts the nose at your 90.5" mark, roughly, and then do the "sub reverse" procedure that I sent you by e-mail. Also, set up a…
Stadank0, 27 October 2018getting some weird sub behavior.Put everything back the way it was including the insulation up above and I can't replicate what I got last night. Sending another file…
Soundman2020, 27 October 2018It's not cables, so I wouldn't worry about that. I'm guessing one of three things: 1) The subs don't actually go as low as they are advertised as going, or the…
Stadank0, 27 October 2018Especially since I was getting some really cool measurements last night.. Been trouble shooting this all day to no avail. I even wondered if the tension of my replaced…
Soundman2020, 27 October 2018Mystery solved! A combination of the physical position of the sub in the room, and the "phase-invert" switch on the sub... plus maybe the sub-par crossover circuit in…

Page 19

Stadank0, 28 October 2018Had an interesting day sub placement testing... :horse: With 2 subs I am able to hit multiple issues..I then put some massive eq on it! This will ultimately be Stuart's…
Soundman2020, 1 November 2018"Set of 7". That's the complete set of REW measurements that I need, to get the full picture of how your speakers and room are performing together. Using my cryptic…
Stadank0, 6 November 2018OK...Here it is. Still have to do some tweaking, screw hole patch and touch paint....I'm in love :mrgreen: The pictures do seem a bit warped....thankfully it looks more…
Soundman2020, 6 November 2018Very cool, Frank! VERY cool! :thu: Shoot me across a "set of seven" REW tests if you feel like, it so we have a true acoustic picture of the room before the desk goes…
Soundman2020, 6 November 2018I was actually thinking of suggesting those for you a while back, but then I figured you'd shoot me, when you heard what those little things sound like, next to your…
Stadank0, 6 November 2018Thats the idea.... I have a set of bm15 passive speakers with a bryston amp that I just can't part with so I'm going to put those in the live room with the other…
Stadank0, 10 November 2018Alright....Another round of miserable bass testing..many hours and hundreds of measurements spent chasing my tail! :horse: So I think I can be happy with the results.…
Soundman2020, 13 November 2018Yup, but not by much. Depending on the location, the times are around 210 ms - 240 ms. Much too low for good tracking: there's basically no room sound at all in there:…

Stadank0, 13 November 2018That's why the second work station has been so useful up till now...there is enough clarity at that those decay times. Hoping we can find a way to make that second work…
Soundman2020, 17 November 2018The model is getting to be pretty big now, with all the details in there. It's around 85 megabytes. SketchUp start bogging down with files that big, on systems that…
Stadank0, 19 November 2018Got some much needed rain coming our way...Will probably be slowed down a day or two during the stain and clear coat process. The hours do rack up! No pun intended.....…
Stadank0, 20 November 2018The major fires aren't close, but there are several fires that have popped up around me in the meantime. Fortunately, our firefighters are amazing and have put them all…
Stadank0, 23 November 2018Well despite getting a sinus infection from sawdust and smoke and Thanksgiving going on, I managed to get some work done. Still have to do all of the clear coats and got…
Stadank0, 27 November 2018Hi, I got the sheet of off of ebay. If you look up perforated sheet metal, you should get results. Pretty sure that's what I did. Mine is aluminum which I recommend for…

Stadank0, 29 November 2018OK...The desk is in the room but things are still rough. Stuart, I tried building some little shelves for the feet but the screen is way too close. The screen is going…
Stadank0, 29 November 2018Cool....I'll look into that. I'll do a quick REW. I had to tweak the subs and still need to do more. Things changed of course. I'll have something in about 30 minutes.…
Soundman2020, 29 November 2018I'd really, really, really, REALLY suggest that you give it another go with the KH805 under the window!, sideways... 8) :D It will fit... Start out with JUST that one…
Soundman2020, 29 November 2018:lol: :lol: :lol: Think of it this way: It will knock your socks off! And thus it will keep your toes warm in winter, and massage your feet too, if you turn up the…
Soundman2020, 29 November 2018:thu: Start with JUST the KH805... experiment with phase and cross-over, to get it reasonable. Keep the others off, and send me a REW test like that. Then set up JUST…
Soundman2020, 29 November 2018:yahoo: :!: I just saw the new REW data for the sub tests you did... and I have to admit that you are right: The Neumann DOES win :) 8) 8) 8) (I really hate to say "I…
Soundman2020, 30 November 2018:lol: :roll: :horse: OK, instructions for the "string trick"... Carefully measure the distance from the very tip of your measurement mic to the acoustic center of your…
Stadank0, 30 November 2018Quick thought, We do have the option to tilt the top a smidge if your interested.... To elaborate on the Neumann... Not sure how I missed putting it more out in the room…

Soundman2020, 30 November 2018There is an improvement, yes, but the reflection is still there. Slightly lower intensity, and slightly earlier in time (very slightly!). Here's what it looks like:…
Stadank0, 30 November 2018I'm having a hard time understanding your string directions. I don't understand the how marking a spot with a sharpie comes into play. I also don't understand the…
Soundman2020, 30 November 2018The sharpie just marks the exact length on the string. The distance that you are trying to trace. If you don't like sharpies, then you can also use a pen, pencil, nail…
Stadank0, 30 November 2018OK...I sent you another file..AS you can see in the pic, The right side needs a bit more coverage. Also, the monitor controller is affecting that side. I could mount a…
Stadank0, 8 December 2018Well, Things are chugging along. Stuart is working away on the digital tuning and I'm getting all of the details in order. Cabling, finish, trim,etc....Gonna let Stuart…
Soundman2020, 18 December 2018Yup. We ran into a very strange issue with the sub, where the input gain control on the sub itself appears to affect only part of the spectrum: it does not reduce all…
Stadank0, 18 December 2018Hey Greg, As of yet, I don't know....My sweetwater guy is going to put in a message to Neumann, but I don't expect a reply until after the holidays...I haven't run this…
Soundman2020, 19 December 2018I don't see how that could be the case at all. If the mic was faulty and did not have flat response, then we would have seen that already, in the other tests, both with…

Stadank0, 19 December 2018Thanks for the praise! The acknowledgement means a lot to me.... The sound quality that we've achieved here, by far exceeded my expectations. When I started treating…
Soundman2020, 19 December 2018Thanks for the comment, Jakob! As soon as Frank's place is completed, yours is next on the schedule! :) Your place has it's own unique challenges, but I'm confident the…
Soundman2020, 3 January 2019Greg never exaggerates, of course! Hyperbole is not in his dictionary.... :) :lol: 8) I don't recall exactly, but it was something like 93%. If you search back around…
Soundman2020, 9 January 2019Just a quick update for all who are following the thread: We took a break over the year-end, of course, and there's been a few glitches to iron out, but the final tuning…
Stadank0, 17 January 2019Hi Stuart, now that we're past the initial shock and awe :ahh: ....I'd like to get back on the same page. Let me know if my current wishes for the LR are unclear. We…

Soundman2020, 25 January 2019Thanks Frank! Yup. Recovering from minor surgery. Nothing serious, but I do have to say, I have developed a newfound hatred for doctors... :) Also, Frank's Control Room…
Stadank0, 17 October 2019Hi All....I'm back! Due to changes in management, I have returned from exile :cop: ....Needless to say, things did not end well between Stuart and I. I'm not going to…

Stadank0, 27 November 2019On a side note....I'm having an issue with transmission loss in the LR. I'm looking for anyone who might the answer to this question. What is the best glass panel…
Stadank0, 27 November 2019Thanks John, Much appreciated. I'm Sure that I can..Just have to put spacers in to fill the 3/4" gap. Just to be clear. Plate glass is better than a two 1/4" piece…
Stadank0, 18 February 2020Been ahwile....I had a lot of bad weather, then I was just plain using the studio and in no mood to tackle this...Happily, I'm down to a solid process and should see the…
Stadank0, 19 February 2020Actually, something has been on my mind for awhile. Does anybody care if I keep posting? My purpose for this thread was to give Stuart an incentive to finish my project…
Waka, 19 February 2020Hi Stadank0, I've had a similar experience to yourself. I've not been very busy on my studio for a while as life has got in the way a bit. I noticed that the views are…
Stadank0, 19 February 2020Thanks for the replies guys.....much appreciated. I have mixed emotions about this whole experience for obvious reasons. On the professional side, I want nothing to do…
Stadank0, 20 February 2020Moreover, you have to figure out how to build most of these features yourself... Even with a good bit of building experience.. things often take more than twice as long.…
Stadank0, 22 February 2020I used what's called a "maker space" if your in the states. Its a coop of machinery that you pay a membership to have access to. I stumbled into that through word of…
Gregwor, 22 February 2020Frank, I know we haven't stayed in touch as much as I would have liked but I truly feel like I made a friend here on the forum! Life has been so damned busy (trying to…
Stadank0, 2 March 2020Thanks man! Your comments were just what I needed....I'll stick around! What I went through on the "professional" side of things has left me very bitter towards the lot.…

Stadank0, 29 March 2020Ok all, its been awhile but I certainly stayed busy. Fortunately I can stay functional even with the virus keeping me at home....So I'll be doing a series of posts to…
Stadank0, 29 March 2020First of all a couple of model pics to illustrate the door function....Fortunately the room sounds awesome to me without the doors being done yet. I'll need to finish…

Stadank0, 16 October 2020Thanks! Probably won't be any measurements soon after cause I'm going to be slowly adding reflection back. I don't expect the doors to change the equation much up front.…
