amac2673, 6 December 2013Hello everybody! I have been reading here for a while and getting as much info as I can. I have been playing, performing, producing and releasing music for over 15 years…
amac2673, 7 December 2013Oh, I forgot to mention that in ceiling across the front of the room where I am planning to put my desk there is a branch HVAC line running perpendicular under the…
Soundman2020, 10 December 2013Hi Allen, and welcome! :) That's an excellent starting point, and it even has a good room ratio. Lucky guy! Just clarifying here: so the studio is going to be on one…
amac2673, 10 December 2013The basement is for the most part daddys domain, and there isn't a galactic war that's more important than daddy making music :wink: Does that mean that if I'm playing…
amac2673, 11 December 2013Every time I attempt to upload any pics I get this error? Can anyone explain? Just so you know I am trying to upload some jpgs from Sketchup that are within the…
amac2673, 11 December 2013Here is what I am thinking, the ceiling above the desk is angled down for both acoustic reasons and the fact that an HVAC branch line is in that part of the ceiling…
amac2673, 11 December 2013Here is a pic from the back corner of the room, you can see in the ceiling the branch of the HVAC, the reason part of it has been closed in is because I moved the wall…
amac2673, 13 December 2013Two questions, I was looking through some more posts and I saw that John "at least in one post" did not like using metal studs in the studio and preferred 16" OC as…
Soundman2020, 27 December 2013Good to see that your family has their priorities right! :) 8) Right, as measured in dBC, and assuming that you build it right... OK, so currently just a hobby studio,…
amac2673, 28 December 2013What you are looking at in the picture is the existing soffit around the HVAC, the wall was moved 4' out and that soffit around the vent had not been demoed yet. It has…
amac2673, 10 January 2014So I got my Mechanical, Electrical and Building permits today. I have started adding mass to the subfloor above by adding double 5/8s with GG between the joist and will…
amac2673, 10 January 2014Another question, I have been back and forth on the soffit vs free standing speaker mounting. I currently have JBL LSR28p's which are rear ported so probably not the…
Soundman2020, 14 January 2014Aaahhh! OK, that makes more sense. That would be fine. That might not be legal. Some building codes do not allow one habitable space to vent directly into another…
amac2673, 14 January 2014Hi Stuart, thanks for the reply! So I am leaning heavily towards getting some Adams, I'm not sure whether to go with the 7x's or the F7's though. I have read that the…
amac2673, 17 January 2014So I've been doing some redesigning in Sketchup for the soffit mounted option and RFZ type of construction. I think my design is ok, BUT I am planning on having a 4…
amac2673, 18 January 2014So, I have been playing with Sketchup a bit and redesigned the front wall a little. I moved the soffits closer to the center of the front wall which allowed me to move…
Soundman2020, 18 January 2014Your best option would be to not do that! :) The theoretical best location for your head is 38% of the room length: that's where the modal response of the room is least…
amac2673, 18 January 2014Ok, pulled the desk back from the wall a bit, my head/listening position is at 6 1/2 ft from the front wall, I threw in some mock ups of Superchunks in the rear corners…
amac2673, 21 January 2014So here's the big question.... I have a pair of JBL lsr28ps, they are great monitors but I do not think I have probably heard them at there best because I have never had…
Soundman2020, 23 January 2014Looks good! Did you check those angles by ray-tracing? The look a bit small to me, for that size room. Both concepts work. The basic idea is the same: you have a very…
Soundman2020, 23 January 2014And they are rear-ported, which also makes then unsuitable. The basic issue is this: by NOT soffit mounting, your monitors can not EVER sound their best, simply becuase…
amac2673, 24 January 2014Hey thanks for the detailed response Stuart! Much appreciated. What you say about soffit mounting totally makes sense, I think you swayed me back in that direction. I…
andy_eade, 25 January 2014Greetings fellow Virginian! My wife and I almost bought in Gainesville but ended up in Leesburg for the new family home / studio. It's great to know there's someone…

amac2673, 25 January 2014Hey what's up Andy! Have read your first build thread a few times already. Too bad you didn't buy in Gville, I could have just gone to your house to record! As far as…
andy_eade, 25 January 2014I used faced insulation only for the exterior wall cavity. All the other walls and ceiling I used unfaced as I recall. I did see in your earlier post that your family…
amac2673, 25 January 2014Ya having the family in construction is a definite bonus, I have access to about every tool you could think of. So far I've been doing it all myself which has been very…
andy_eade, 25 January 2014I thought about soffit mounting but didn't really know enough about it and decided to see how the control room sounded and then treat problem areas instead. I guess it…
amac2673, 25 January 2014Ya I've been back and forth and back and forth on the soffit thing, in order for me to do it I need to sell my JBL LRS28ps which I have been mixing on for 10+ years.…
andy_eade, 25 January 2014In my last build I did GG on the beef and the inside leaf on my live room. I'm not sure if that was overkill but I'm all for saving next time around given how expensive…
amac2673, 26 January 2014Yup definitely going to put the cleats up! Ya, I bought 5 gallon buckets of that stuff, enough to do the entire inner leaf including the inner leaf ceiling. Ya know this…
Soundman2020, 26 January 2014The soffits ARE the new wall! If you start out with just superchunks in the corners to visually represent the soffits, then the front wall of the room is the hard,…
Soundman2020, 26 January 2014The original A7s, plus a Sub-8 to extend the bottom end down lower. But I would recommend the Sub-10 instead of the Sub-8 if you want to add a sub: the Sub-8 is a little…
amac2673, 26 January 2014Cool, look forward to seeing the tests.... I found a pair of A8x's for a really good price and decided to get them. So the JBLs are going on the market. Also picked up…
amac2673, 30 January 2014Question... So I have this trunk HVAC line going perpendicular under the joists in my room. This is the HVAC feed for the studio. I was originally thinking I would build…
Soundman2020, 30 January 2014Your basic plan is correct, but you also need to fix that "open on top" part, by enclosing it 100%. If you did that, it would be in between your two leaves, and become…
amac2673, 30 January 2014I was afraid you were going to say that. :cry: Oh well, I've gone this far with the ceiling beef up, which has been as much fun as going to the dentist, I'm not going to…
Soundman2020, 30 January 2014:) I'm taking a wild guess here: I think you already know the answers to at least two of those, but you are really, REALLY hoping I'll tell you something different!!! :)…
amac2673, 30 January 2014Ya that's what I thought... :x If I'm not going to do it right, why do it at all! So with that microwave vent and that other smaller flex duct, should I insulate and…
amac2673, 5 February 2014Still wondering about what to do with with that microwave vent and that other smaller flex duct, should I insulate and close the bottom of the bay up or build a tighter…
Soundman2020, 13 February 2014Do the easier thing: insulate and close off the entire stud bay. Much easier! :thu: :shot: To my way of thinking, the purpose of having NS10's is so you can hear what…
amac2673, 13 February 2014Hi Stuart, Thank you once again for the feedback! I think I have designed what I want to do finally! I feel like I want to do a slot wall bass absorber on the rear wall.…
amac2673, 17 February 2014Does this mean that the speaker box does not need any rubber/neoprene material inside the speaker box decoupling the speaker from the box? Does it also mean the it does…
Soundman2020, 17 February 2014For John's method, yes that's correct. It's a very tight fit. Once again, for John's method, yes it can touch. However, you do need LOTS of mass and a very rigid…
amac2673, 18 February 2014Awesome thanks for the clarification Stuart! I was planning on building the soffit baffles with a sheet of 3/4" MDF and a finish sheet of 3/4" Birch laminated plywood on…
Soundman2020, 5 March 2014That should be fine. Looks good to me. That should keep the speaker firmly and solidly attached to the soffit, but also make it easily removable. Good idea! :thu: Looks…

amac2673, 24 March 2014Alright! Finally finished beefing up and sealing the outer leaf! What gigantic pain in the --- that was! I laid out my walls and got the first built and temporarily…
amac2673, 25 March 2014New day, new wall. I got the first angled wall built, I'm hoping to get the front wall and possibly the angled one on the other side done today too... We'll see... I'm…
andy_eade, 25 March 2014Lookin' good Allen. Great to see that the beef-up is finally behind you. You did two layers of 5/8" beef correct? Are you already noticing a difference in the noise from…
amac2673, 25 March 2014Hi Andy, Yes its for the structure, I'm attaching the joists to the top plates "decoupled ceiling", actually as far as the inner leaf is concerned I'm trying to go a…
amac2673, 1 April 2014Ok, almost done with framing, finishing up the ceiling joist right now and I have a question. Is there any difference between angling the ceiling down towards the front…
amac2673, 6 April 2014Ok, finished the framing, will take and post some pics this weekend, I decided against the outside mounted fan for various reasons one of which being not wanting to cut…
amac2673, 9 April 2014Ok, Finished the framing! Starting to look like something now! I decided to go with putting the HVAC return silencer in the exercise room that is adjacent to the studio.…
amac2673, 16 April 2014Finished building the vent silencer and got in the open space between the foundation wall and the splayed wall at the front of the room. just need to measure the vent…
amac2673, 16 April 2014Thanks man, I used staples. Next up wiring the studio both electrical and putting my snake in the wall. I think I am going to go with surface mount outlet boxes and…
amac2673, 17 April 2014One of the outer leaf walls in my studio is common with my basement rec room, more specifically on the other side of that wall is a 120" fixed projector screen with in…
amac2673, 28 April 2014Quick update, Finished all of the fire blocking, it was a bit of a pain. I furred out the top plates to within an 1/2 to an 1" all the way around with either 2x4 lumber…
andy_eade, 28 April 2014Hi Allen, I think it depends on if you have true RFZ in the vertical plane. As I recall you did do 3d ray tracing for your RFZ design correct? If the angle was designed…
amac2673, 29 April 2014Hey Andy hows it going! Ya my design is a true RFZ, I did all the appropriate ray tracing for both walls and ceiling and have no reflections coming off the either at the…

amac2673, 25 May 2014Not sure about the neoprene, I ordered what I linked and wrapped it around the gap twice, stapled, glued, and sealed it to the vent. It was quarter inch neoprene so I…
amac2673, 29 May 2014I have one outlet on a dedicated circuit that is just hanging in the front corner of the room, you can't see it in the pic because its right behind the shop vac. I am…
Soundman2020, 29 May 2014It's not just about sealing, although that is very important too: It is also about replacing the lost mass behind the electrical box. When you cut a hole through your…
amac2673, 9 July 2014Hi all, Its been a while since I posted but I have been making lots of progress. I passed all my inspections and got my final! I built my soffits, hangers, front wall…
amac2673, 9 July 2014Hi Stuart! Thanks, it's been a lot of work but when I started putting the floor down I was like, holy moly this is actually looking like my design! (Due in small part to…
Soundman2020, 10 July 2014That's cool! Just checkin'.... it's always good to have an extra pair of eyes looking over your shoulder while you build.... :) Absolutely! That will be your "baseline"…
amac2673, 18 July 2014Built me a very HEAVY door that I hung myself... 125 lbs, 2 pieces of MDF laminated together with 2 pieces of 1/4" plywood, I used a 2x6 for the hinge side spine that I…
amac2673, 24 July 2014Small update, got the monitors powered up yesterday gave them a listen, I am supposed to receive my SPL meter today so I will do my REW tests then but even just giving…
amac2673, 28 July 2014Here ya go! I did the first tests left, right and both. I also did another test with just both after having stacked up two bags of Roxul SS floor to ceiling to see how…
amac2673, 11 August 2014Finished my back wall treatment and the room is really starting to look and sound nice, bass really tightened up! Image not preserved: 2014-08-11 11.21.00.jpg Definitely…

amac2673, 9 September 2014Thanks for taking a look. Can you tell me how you determined the early reflection point after the cloud, so that I know what to look for after making some adjustments?…
Soundman2020, 9 September 2014Can you send a couple of photos of that cloud, and the room in general? That would help. The additional path length is about 44" (in other words, the reflected sound is…
amac2673, 11 September 2014I did the string trick you suggested and the only hard surface that the center of the tape hits is the floor. I haven't put the desk in the room yet as I am still…
amac2673, 12 September 2014Hey, thanks a ton for looking at my readings, it is much appreciated! Can you tell me what graph and reading specifically it is that is telling you about the reflection…
Soundman2020, 12 September 2014It's on the "Impulse" button, which shows the impulse response of the room. (You can also see it on the "Filtered IR" button: same thing). Turn on the "ETC" curve, turn…
Soundman2020, 12 September 2014One other thing. You said: "the only hard surface that the center is touching with equal distance between the tape..." It doesn't have to be the center of the tape! It…
amac2673, 12 September 2014Ya, I did check other to see if it would hit other things and it will touch the cloud in multiple places, but everywhere it touches it is on the fabric and not on a hard…
amac2673, 15 September 2014Here some desk build pictures, just have desktop left to cut and laminate and then I'm in business. Image not preserved: 9.jpg Image not preserved: 8.jpg Image not…
amac2673, 17 October 2014Thought I would add some pictures of the finished product. I put up some 705 panels per Stuarts suggestion to tame some of the 2k-8k stuff. Also, when I put the desk in…
amac2673, 17 October 2014Thanks man! I started construction on it around the first week of December 2013, and built it completely by myself with any spare moment I had. There were times when I…
Soundman2020, 17 October 2014THUNK! That's the sound of my jaw hitting the floor... WOW! I mean !WOW! Allen, that is one great looking studio. Really, really nice. A job well done. Congratulations!…
amac2673, 17 October 2014WOW BACK AT YOU! That is awesome! I can't believe made the list! Not only is it nice to look at, but the functionality is insane! I have been playing/recording music for…
andy_eade, 2 January 2015Hey Allen, Your build has been an inspiration to me, and I'm sure to others. Thanks so much for providing the pictures and updates along the way. I recall on my last…
andy_eade, 1 October 2015Hi Allen, I'm hoping you're still around to answer a question I have about your beef up. I noticed recently while studying your beef up pictures back on page 4, that…

amac2673, 3 October 2015Hi Andy! Since that is a gas line made out of heavy galvanized steel I was not worried about sound traveling through it to the rest of the house. It is not like the…
amac2673, 21 October 2015Ya our gasline goes upstairs too. We have a gas fireplace but no issues with noise do to the gasline. It is such a small dense pipe vibrations don't carry through it.…
