I have a couple of questions on your treatments:
- Front Wall. Did you use Roxul for your front wall treatment? If so, how did you secure it.
- Back Wall. How did you build your panels for the back walls? 6" thick with 3" air? Ripped 2x6?
- Side Wall. Did you do any panels for the side walls? 3" thick?
With the addition of my SEOS surrounds, I have a strong need to tame the reflections. Once I get my rack and pj mount built, I can bet going on treatments.
I know! Trust me every time I watch a movie I dream of those components in the attic...... realistically it will be way after new years when I get started.
Before I build them I am going to finish my treatments and finish building out my subs.
my current treatments(besides soffits and rear projector enclosure) are temporary.
Side Walls- 2x4 panels with 4"OC703 and 4" air gap.
Ceiling - was same as side walls ^ but I had to take down to install soffits.
Front wall- 2x4 panels same as above behind each LCR.
Corners- All vertical corners trapped and new soffits treat minor corners created by cathedral ceiling.
I still have three packs of ROXUL I'm planning to install into the theater. Here are my plans for it:
1. Two 6'x6' panels on each of the side walls for primary reflection points, 3.5" ROXUL with 4" air gap.
2. Some ceiling treatment, but haven't decided on form of this. it will be 3.5" ROXUL with 4" air gap though just not sure how it will look yet.
3. Front wall- I have been toying with a unique concept for the front wall. I'm pondering building my treatments with a huge air gap. actually more like a baffle wall filled with ROXUL. this would have cutouts for my mains and subs. I asked sometime back and some of the acoustical brains said it would work well to do it that way. SBIR really jacks up my midrange currently and I want that completely fixed in the end.
4. my rear wall has that projector enclosure which is filled with ROXUL, but as far as the wall below I'm not sure I'll absorb it. I'm prob going to use some polys in the rear and maybe craft paper some of the soffits behind the seating if the room becomes too dead. Right now the room still needs lots of absorption up front IMO.
Sorry so long really thinking out loud here, since treatments are my next "big" project.
