sonolink, 27 August 2010I have been working on my sketchup plan and I have come up with this: File not preserved: StudioSonolink7.skp I'm about to begin in a day or two so I would sincerely…
Soundman2020, 28 August 2010Well, I'm trying to understand what your intentions are, but really I can't see the acoustic purpose of they way you have it laid out. I see several issues there: 1)…
sonolink, 28 August 2010Stuart, Thanks for your reply. I'm sorry that my post is a bit confusing. I will try to clarify things :) Here's an updated file for you, with some elements that were…
AVare, 3 September 2010Stuart is handling your design analysis wonderfully. Many, if not most, of the professional class designers here will not disrupt a topic with distracting information…
sonolink, 4 September 2010I appreciate your advices gentlemen and thank everybody for their time and help, especially Stuart. Understood. I didn't realize my questions were asking for too much…
xSpace, 4 September 2010"I didn't realize my questions were asking for too much accuracy...please accept my most humble apologies, sir." It's all about accuracy, as you have already recognized…
Soundman2020, 7 September 2010Not quite!!!! :) That's an improvement, and you have fixed a few of the issues, but there are still several more to go. Let's start with the big ones: Image not…
sonolink, 7 September 2010Dear Stuart, I'm glad you're back 8) My speakers are Yamaha HS80M. The speaker unit I had in mind was the one on John's "components.skp" file. This unit's baffle doesn't…
Soundman2020, 8 September 2010Uh ohhh! Isn't that a rear-ported design? As far as I know, there is no way to successfully soffit mount a rear-ported speaker. Sorry to be the bearer or bad tidings,…
sonolink, 8 September 2010Stuart, thanks for your prompt answer. I am aware that a rear port speaker might mean some problems when soffit mounted, BUT, after taking into account that my speakers…
Soundman2020, 11 September 2010OK, better! Your soffits and room geometry are making more sense now, but you still seem to be missing the point on a couple of things. The hangers in the front corners…
sonolink, 12 September 2010Stuart, Thanks a lot for checking out my plan and for your comments :) The "box" is a copy of John's "speaker unit" in his components.skp sketchup file. My speakers are…
sonolink, 14 September 2010My first attempt at Ray Tracing... I have erased most elements in the sketch to keep the file size down. The dotted lines represent the speakers sound (duh!). I drawed…
sonolink, 14 September 2010Carsten, thanks for your tips and for chiming in (not that I get bored with Stu :mrgreen: ) I read that thread about John's hangers some weeks ago (or was it months?)…
sonolink, 14 September 2010Of course not, dear friend, keine probleme ;-) Actually all your input is very welcome indeed (and probably well needed...) Now for a "how to" question, I am worried…
Soundman2020, 15 September 2010Slot walls don't eliminate reflections: they have large hard reflective surfaces. Paradoxically, they are broadband absorbers, too, but that doesn't mean that they don't…

sonolink, 15 September 2010You just did mine mate!! :mrgreen: Thanks for the tip. I never considered tilting the slat wall from the soffit side!! Great idea! Thanks! I have recalculated everything…
sonolink, 16 September 2010I realized my speakers are not centered on my soffits. They are aprox 10 cm nearer the sides than the center of the soffits . Is this a problem? I drawed a new sketch,…
Soundman2020, 18 September 2010I think I already asked this several times, but you never noticed, and now you have already built the soffits without taking this into account: 1) What is the purpose of…
sonolink, 18 September 2010Thanks for your replies, gentlemen. They are indeed. You can see it in the last sketchup file I attached a couple post earlier. Here's a Top View: Image not preserved:…
Soundman2020, 19 September 2010Actually, yours is NOT the same as John's! John's design does NOT have that intermediate box inside it: Yours does. Take a close look: First, John's design: Image not…
sonolink, 19 September 2010Stuart, I think I understand it now: basically, what you call the "intermediate" box should be my drywall (inner leaf). The bass trap covers all the soffit width and is…
sonolink, 19 September 2010Thanks for your reply, Glenn. No, it doesn't need to be modular at all. Ok, so to make sure I understood all this properly: 1- I should build a wooden frame to hold the…
sonolink, 20 September 2010Glenn, thanks for your fast reply :) A couple more questions if you don't mind: 1-why not fill everything with wool instead of hangers? 2-On the previous pic you posted…
gullfo, 20 September 2010the opening under the baffle plate is the entry point. not shown in the drawing (besides the closed speaker box and except for the box vent and wiring opening) is lot's…
sonolink, 20 September 2010I know the Slat wall itself needs to be sealed to work, Stuart. My question was oriented towards the bass trap depicted on the pic Glenn posted, as it seems an…
sonolink, 20 September 2010Glenn, I am sincerely grateful for all your comments, especially for your clarity :mrgreen: I am now building the soffit and slat walls frame. I'll seal between center…
sonolink, 21 September 2010Finished the right soffit and slat wall frame. Gotta calculate the hangers different sizes now. I cant seem to find homosote around here. Stuart, or anyone, do you know…

sonolink, 22 September 2010Soffit frames done and checked :mrgreen: I need to build the slat walls now but I have a doubt all of a sudden. My slats need to be at a 20 degrees angle minimum to…
gullfo, 22 September 2010are you accounting for the surface angle when you ray trace? I see a lot of folks ray tracing and they don't account for the surface angle to determine possible…
sonolink, 22 September 2010Glenn, Thanks for ur reply and link. By "surface angle" do you mean angle of incidence/reflection? The way I Ray traced is as follows: 1-Draw a line from the speaker's…
sonolink, 23 September 2010Mmmm....that's very interesting. I guess then that putting that absorbent column I draw a couple posts earlier is not a good idea? I have no real competence to talk…
sonolink, 23 September 2010John, Thanks for chiming in. Your advice is much appreciated :mrgreen: Of course,.....you're right. It's not that I'm not realizing, I'm simply being an idiot and I…
sonolink, 25 September 2010I think in my case it was more like a kick in the face, really :lol: Soffit framing done. Need to add hangers and the absorbent part for console reflections. Yesterday I…
sonolink, 27 September 2010Glenn, Thanks for ur reply. I just screwed them to the concrete floor. Next I'll fill them with sand and then I'll screw the black box in. I doubt I can go more solid…
sonolink, 27 September 2010Glenn, thanks for your reply and for the pic :) To make sure I follow you properly, please allow me some questions: 1-The clouds are absorbent panels, right? If so,…

sonolink, 27 September 2010Thanks Glenn, I think by now I must owe you way more than just a few cold beers!! :D I'll do some reading on clouds these days while I finish building the soffits and…
sonolink, 29 September 2010Cool, thanks for the confirmation :mrgreen: Busy with the hangers...while having a break I had a go at the Harman Mode Calculator and ended up with this: Image not…
sonolink, 29 September 2010Sorry to be a pain, but I have a few questions regarding the slat walls... :oops: Here goes: -If I'm not mistaken, John says to use 100mm,50mm and 25mm wide slats. What…
gullfo, 29 September 2010on the slats, 20mm-40mm thick should be fine depending on your calculations. width and spacing, lot's of time randomly arranged and spaced to break things up visually as…
sonolink, 29 September 2010Glenn, Thanks for your fast reply :) mmm.....ok...I haven't done ANY calculations whatsoever, except on the angle of the slat wall. I just downloaded John's…
gullfo, 29 September 2010the picture you show is John's inside-out wall design (which I think you are not doing?) the components file contains freestanding components which are build like…
sonolink, 30 September 2010Ok, I'll breathe and stop over worrying, I promise :) Well actually, it all began with the inside-out wall for me:) Then, for a number of reasons (long boring story) I…
sonolink, 30 September 2010Excellent! I'll go with this sequence then: 100mm slat/2,5mm slot, 50mm slat/5mm slot, 25mm slat/10mm slot and start over, top to bottom :mrgreen: Regarding your Google…
sonolink, 1 October 2010quoted from: http://www.ethanwiner.com/acoustics.htm ... 0or%20dead Please don't get me wrong. I am not trying or want to start an argument here. I remember now that at…
sonolink, 5 October 2010Weekend is over, back on the road!! So, speaker stands filled with sand, central slat wall frame (in between soffits) nearly finished. Man, do I hate caulk!! :wink: Only…

sonolink, 5 October 2010Excellent :D I'd like to know your thoughts about the back of the studio. The rear wall in my room is uneven as you can see on the attached pics. I thought that filling…
sonolink, 6 October 2010Oh I see what you mean. The couch is definitely a must 8) The green bit on the wall between the superchunks is 50mm rockwool covered in cloth. Is that enough absorbers,…
sonolink, 6 October 2010Glenn, Thanks for the pic. That looks really cool, and it would probably also sort out the bass trapping for that end of the ceiling...a couple of BUTs though (sorry to…
sonolink, 16 October 2010Hi again, some updates: I have finished most of the framing. Now I need to fill with fibreglass. Found color scheme and cloth. Got wood for slats and soffits. Build…
sonolink, 17 October 2010Yes, my intention was to follow your example cloud pic. I just get the impression that the ceiling will be very low. -Can I hang the clouds as near as possible to the…
sonolink, 18 October 2010mmm btw, any illumination/lighting ideas/suggestions? I'd like to have some ambience lights (initially I thought Of creating these by placing bulbs behind wall panels,…
sonolink, 18 October 2010You mean like three levels, i.e. 1-ambience 2-desk and couch 3-100% bright That's a cool idea and rules out dimmer problems. I was actually thinking on using an…

sonolink, 18 October 2010Of course!! Sorry, I guess it's "brain dead day" for me today...... I didn't know what track lighting was (by that name, anyway) I think I'll put three switches on the…
sonolink, 2 November 2010I just realized something: my speaker boxes are really tight, so much so that the only way to pull the speaker out is by slightly tilting the box. I won't be able to…

sonolink, 8 November 2010Danke schone Glenn. You're my hero!!!!! 8) I was so worried I had to rent a van to go to the nearest big town (200km away) to bring pink stuff.....so that's great…
sonolink, 12 November 2010Man do I HATE stapling plastic sheet to the ceiling!!!! :horse: Some pics as promised :mrgreen: Image not preserved: IMAG0104.jpg Image not preserved: IMAG0106.jpg Image…
sonolink, 13 November 2010Oh yes, indeed!! The sound is getting better, clearer, and awesome, apart from the ground to ceiling flutter. I have done roughly 20% of the ceiling and when I…

sonolink, 7 December 2010Thanks for the tips, Glenn. I think I'll go for "toenailing" screws through the top and bottom (slat width). I'll screw in a wooden guide first, on top of which I can…

sonolink, 13 January 2011Thanks your quick reply Glenn, I'll try to keep it tidy from the start. It's the best way to keep it tidy on the long run :) So, the bookshelves will definitely go…

sonolink, 20 January 2011Ok, I found something that does not harden upon drying, is 500% elastic and absorbs vibrations and movement. I guess this should be ok. Is it ok to use this also between…
