JohnH, 22 December 2010Hi, I've just joined after studying this massive, wonderful forum for many months. Still in the research/design phase but I have an empty 30 ft x 50 ft building attached…
JohnH, 22 December 2010Thanks Andre, Merry Christmas to you too, and I wanted to thank you for all the helpful responses that you haven to everyone else. I'm in process of fulfilling the…
AVare, 23 December 2010Regarding budget, there is no hard and fast number for construction costs for studio building, but as a starter good studio building costs as much as premium/luxury home…
JohnH, 26 December 2010I will take photographs for you guys as soon as its daylight again here. Regarding floor capacity, what are we looking for? According to the charts, 2"x12" on 16"…
JohnH, 26 December 2010Here are some photos. This is the north wall. The road is just on the other side of this wall. The insulation was put just in that one section by the previous owner, a…
gullfo, 28 December 2010thanks for the photos! i think the concern was the floor - isolation needs mass and one of the best ways is concrete. there are several approaches here - one could be to…
JohnH, 28 December 2010Thank you Glenn, I have that book and continue to study it daily. Great idea about using a laptop and measurement microphone. - Any suggestions on software adequate…
JohnH, 28 December 2010I'll check out the plugins. Your layout is logical. Should I just build a plain old rectangular room and treat it acoustically? Or is there any reason to use the John…
JohnH, 30 December 2010Glenn, Yes, I would like to soffit mount the speakers. I been using Yorkville YSM-1 as near fields for years. You think they be adequate for soffit mounting? Also I'm…
JohnH, 5 January 2011That would be great! Here's my best attempt yet at a to scale, properly oriented, accurate to 0.5 inch sketchup. File not preserved: johnh_mix_track_room.skp (edit)…
gullfo, 5 January 2011room location - this is a tricky one and it really boils down to where you are likely to do acoustic recording or very low level critical listening which could be…
JohnH, 1 February 2011After many hours of sketchuping and consulting with anyone I could drag in off the street I have an updated sketchup file of the entire building (which I can't upload…
JohnH, 11 February 2011Glenn, thanks so much for taking the time to chat with me. Based on our talk, we're looking at building a double wall rectangular control room with flat ceiling with one…

xSpace, 11 February 2011Figure A is not a triple leaf. It is a single frame/two sided assembly...a coupled assembly with another hard boundary below it. If you turned it 90 degrees in any…
gullfo, 12 February 2011Brien - what we discussed was a decoupled room within a room approach to mitigate the flanking as much as possible to solve an issue due to low frequency rumbling from…
JohnH, 12 February 2011First off, I appreciate the help very much. This is a real gift that you give and I am grateful. Our plan was to carpet the multipurpose room to dampen the footfall…
xSpace, 12 February 2011I appreciate that Glenn, and your work here. Low rumble in a wooden structure works because it is moving the structure. If another assembly is built, even enclosed room,…
JohnH, 15 February 2011A few questions. 1. Sources for the neoprene? Any substitutes? 2. Is there any negative effect (double walls) if the outer wall is 2x6 construction and the inner is 2x4…
gullfo, 15 February 2011the room design you show is workable in that space. you can use a heavy drape over the door when needed. you can use 2x6 instead of 2x4, in fact using the 2x6 is…
xSpace, 18 February 2011It is an elevated wooden environment. I have a wooden table in my kitchen and whenever drinking buddy slaps his beer onto the table...I feel it second but hear it…
JohnH, 19 February 2011If I were Joe Rock Star, I'd might have the budget to ..............., I'd move to Maui, why would I want to do this in poorest part of Vermont. I just happen to have a…
JohnH, 23 February 2011Glenn, those Mason isolators look like they're only for steel framing. Is the Rubbercal 4119 what you recommend under the wood frame plate for isolation on the inner…
JohnH, 23 February 2011Thanks Glenn, Also not having any luck getting Voxengo Span to appear in Audicity's menu's. I have Audacity 1.2.6 on a windows laptop. Downloaded the lastest SPAN for…

JohnH, 28 February 2011Dumb questions: 1. Is 6 degrees enough of an angle for the inner walls with this design (to send the flutter echos toward the rear of the room to be dealt with later)? I…
JohnH, 4 March 2011Any thoughts on previous post before the inner walls go up> Outer wall framing is underway. Pictures My current "studio". I bang my shins every night getting to my side…
gullfo, 5 March 2011If you can go to 12 degrees that would be best but 8 will be better than 6. You can add soffits later if desired. Yes the door frame and jamb need to be decoupled. If…
JohnH, 9 March 2011More photos for your late night viewing! Added concrete filled lally columns under the LVL beams. Image not preserved: Picture 014.jpg Image not preserved: Picture…
JohnH, 16 March 2011A little more progress. Just about all of the framing is done. We've decide to put strapping up on the ceiling to stiffen up the "floating inner structure", but that…
JohnH, 24 March 2011Framing is complete and all the wiring is complete except for the ground wiring. Two light circuits for LED track lighting, one in the front and two in the back of room.…
JohnH, 25 March 2011This forum has all the answers. Though buried within billions and billions (remember Carl Sagan) of bits of information. Lots of digging required, but its in there,…
JohnH, 27 March 2011OK, The star grounding.......it's done, only took a couple hours. It was easy; while the framing is still exposed. Here are some photos. Let me know if anything looks…
JohnH, 27 March 2011The insulation and sheet rock are arriving tomorrow (March 30, 2011) and should be done in a week. Whats' next? The floor? Test the room as is? I know Glenn will…
JohnH, 29 March 2011Thanks for the feedback Glenn, The ground wires are taped to the Romex until they reach the conduit where they separate. Normally there should be no current flow in…
JohnH, 31 March 2011The outlets in question are all on the same 20 amp circuit. I checked with a licenced electrician and he said it was fine. (Does that mean it's to code, or safe? I don't…

JohnH, 3 April 2011Greetings, We're rockin' on the sheetrock. (See photos below) Attached is a sketchup file of the inner shell to final finished dimensions within 1/4 inch. Note the…
JohnH, 3 April 2011I thought I start with speakers on stands and maybe build the "component" type setup later. Planning on baffle boxes outside the room. (updated .skp file below with…
JohnH, 4 April 2011Just to clarify the term "wall unit", I meant some custom made or modified furniture similar to this, placed along the back wall. The shelves could be filled with books,…
JohnH, 5 April 2011Gotcha. So I'll deal with speakers on stands. Less work, done sooner, then I can get back to music sooner! The first layer of sheetrock is done except for that front…
JohnH, 6 April 2011Takman, I took a look at that pipe again and It IS only clamped to the back side of the inner floating wall with soft rubber cushions, around the pipe at each clamp/stud…
JohnH, 7 April 2011It's 1.25 inch. I probably should have gone larger. The sheet rock is up on the inner walls. I could change it still, but probably will leave it. I wonder if there's a…
BriHar, 7 April 2011Well if you divide the conduit section (area of circle Πr² of inside) by the cross-section of the cable (not the gauge!) that will give you a rough idea. There's a…
JohnH, 7 April 2011Thanks for the tips guys! I've finished the backer rod, caulk, mud and tape on the first layer of wall board on the inner shell today including a 2nd coat of mud. No…
JohnH, 11 April 2011I just ordered a 5 gallon bucket of green goop and a dispensing gun. I shopped around and found substantial discounts. From my vibration analysis days, I well understand…
JohnH, 26 April 2011Progress Report First off, thank you Glenn for calling my room an "awesome control room" in protechtor's thread. I am humbly and undeservedly honored. I do hope it will…

JohnH, 1 May 2011While waiting for the primer to dry, I've been playing with the layout. I have a bunch of stuff to store books: manuals, lyrics in binders, CD's, VHS tapes, cassete…
gullfo, 2 May 2011that looks like a decent layout -- maybe consider a very heavy drape you could pull across (perhaps segments) the back wall in case you find it too reflective. take…
JohnH, 8 May 2011Glenn, I've searched and searched but could not find the FitZ posts you mentioned, but I get the idea. I prefer not to make built in bass traps....attached to the…
JohnH, 9 May 2011I'm not getting a clear picture on the bottom cabinets. Do you mean to put the 2" cloth covered 703 or 705 immediately right behind the doors? Or all the way back of the…
JohnH, 9 May 2011Glennnnnnnnnn! Way cool looking!!! Thank you!!! Doors angled for diffusion. Hard surface to reflect the highs and some perforation to let some sound in. The cabinet…
JohnH, 10 May 2011I have downloaded REW (Room EQ Wizard) I have two but questions Master.... 1. What is an "HH" ? (I have searched long and hard for the answer throughout the entire world…
JohnH, 14 May 2011I guess, I don't just have a gut level understanding of how these slot resonators actually work. Mechanical systems are much easier to visualize. I done some research…
JohnH, 18 May 2011Slot absorbers seem difficult to design with any precision. Experience must make up much of the design process. BTW Glenn, if you're ever in Northern VT you are welcome…

JohnH, 25 May 2011OK, Floors done. Bought some padded underlayment, did a test, made a plywood sandwich... useless. Looked round the barn and found several new rolls or carpet padding.…
JohnH, 3 June 2011Lot has happened in the past week. DISASTER NEWS We had disaster level storms and flooding in the area. Unbelievable amount of rain came down in one night, almost 6…
gullfo, 5 June 2011good thing you built this on the second floor :-) i'd say that since you have no absorption in the room, you are very clearly seeing the floor-ceiling mode, a side-mode…
JohnH, 7 June 2011Glenn, I finished the ceiling soffit today except for the final trim. I might as well get ready to build the cloud(s) while waiting for the 703. Many posts back you…
JohnH, 8 June 2011Very nice looking! If I have studied well, the plastic is to keep fiberglass particles from dropping down, also adds a little high frequency reflection. Two questions:…
JohnH, 27 June 2011Back from vacation and ready to continue the project. The OC 703 is supposed to be in and I'm trying to pick out fabrics. Glenn, I have some questions about the clouds.…

JohnH, 2 August 2011Sorry for being away for so long. Been building the eight clouds and 4 wall absorbers. (along with planning a songwriters workshop and multi-performer concert) These are…
JohnH, 12 August 2011The camera is getting full, but its in the barn and I'm not at the moment. Pictures coming very soon. Promise :oops: Thanks for the kind words Edu. Nice build on your…
JohnH, 13 August 2011Here are the long promised photos. I think building the room was easier. Cutting the wood for all those frames :shock: . I felt like Rain Man in the diner scene. 246…
JohnH, 13 August 2011More photos Image not preserved: Studio Clouds 014.jpg Image not preserved: Studio Clouds 015.jpg Image not preserved: Studio Clouds 016.jpg Image not preserved: Studio…
JohnH, 13 August 2011Thank you Glenn. Guess its time to hang em and test again. I can definitely hear flutter between the rear side walls. Need to make speaker stands, and set up the…
xSpace, 13 August 2011I built my stands similar to what Glenn suggested, but knowing that they would be a "moving" part of the environment, I cut sheetrock to fit around the sides of the…
JohnH, 17 August 2011I picked up the cement blocks today and set em' up and did a little listening and a sine wave slow manual sweep. I've got some very obvious room modes I can hear at…
BriHar, 18 August 2011Fine tune the listening position by moving it back or forward - always testing at each position. Also try moving the speakers forward and back. At each position you can…
Soundman2020, 18 August 2011The answer is: YES! :) Seriously, as with a lot of things in acoustics, it all depends. If the room is large, then get the speakers several meters away from the walls.…
JohnH, 19 August 2011Thanks Stuart, That give me a better starting point. Soffit mounting is an option that slipped off the plate a while back and is no longer possible due to design choices…
gullfo, 25 August 2011best bet is to start out with them close to the wall and move them out a bit at a time - checking for seating effects - i.e does you're sitting position make a…
JohnH, 13 September 2011Well, the clouds are up and to say they make a difference is an understatement. WOW! I'd be happy if I didn't do anything else. The rooms sounds better than any space…
JohnH, 2 October 2011Finally had a minute to upload a photo. As you can see the clouds are up and the room sounds great. I've spent some time modifying the desk, removed the keyboard slide…
JohnH, 14 October 2011I'm looking forward to our 6 months of winter so I can focus on the studio again. (The project slowed down to a crawl during the summer because of outdoor construction…

JohnH, 4 December 2014More pics of the finished studio (and some in process pics) we now call Dreamery Productions. It was a long project and a lot of work but well worth it. Enjoy! John…
JohnH, 4 December 2014Thank you Stuart! I am so grateful for this forum. I learned so much and continue to do so. (its a life long process) I now have the studio I always dreamed about,…
