For a few different reasons, I decided to install a drop ceiling in my theater, beneath the existing sheetrock ceiling. Since the ceiling was a little over 9 feet high, I could afford a 6-7" drop without any feeling of being cramped.

Especially, I was hoping to:

1) mitigate sound transfer to my daughter's bedroom above
2) improve sound in the room
3) eliminate the white reflective ceiling and improve screen image quality
4) provide an easy chase to pre-wire for in ceiling elevation speakers

I went with CertainTeed's Theater Black 2x2 tiles, a semi-rigid spun fiberglass tile with a flat black fabric surface, in 5/8". I then backed all tiles with cut Owens Corning 703 foil faced board, 2" thick. Installation was a combination of myself, my son, a friend, and a professional.

I also added 8 Auralex T'fusor diffusion tiles in the ceiling to scatter some sound, but just absorb. They come white, but I painted them flat black, which I also did for my AC air diffusers.


It begins





My son installed the hangers, screwed through the drywall and resilient channel layer into the laminate beams above






Using an old in-walll speaker location to chase ceiling speaker wires up from the basement rack location







This was a bitch job...

For the AC air diffuser, the drop was too short, nor could I find any obvious adapter to connect to the 8 x 8 box, which was finished flush with the existing sheetrock -



so we improvised, screwing the diffuser into a sandwhich of finished tile/OC703 board (to anchors, shown below on the backside), and then making 8x8 (inside dimension) collars from the OC board (so open on top and bottom) taped with aluminum duct tape. The height was measured to be a snug fit between the sheetrock and the inside of the OC board. We then simply slid the collar between the ceiling and the diffuser/panel "sandwich"', and the snug fit lets the air fall right through from the sheet metal box above through the diffuser in the tile.

I will likely use the KEF CI200RR-THX, which apparently have a dispersion that exceeds the spec...I will post more about positioning in the next few days

Hi Thrang,


Since you have expercience with Mcintosh and Parasound and B&W I think I should ask you this question.

I bought B&W CT8.4 frontspeakers (3) and I'm hesitating between 2 amps: McIntosh mc207 and a Parasound A51+A31.

Is there a big difference in SQ between these amps?

Any advise is welcome.....

I started with a McIntosh 7 channel amp, then went to two channel and finally the 601 monoblocks...

I am running the Parasound monoblocks for the front, and the A51 for surrounds...I do prefer the Parasound sound and would not revert.

Seeing all that work going on around your speakers makes me cringe. I see a guy getting way to close for comfort in one of your pics. No way would I have had the speakers in there during the renno, you are very trusting of the workers

I know, but really no option to remove them easily and on the short timeline, and the room is sunken so they'd have to be carried out up a few steps...I hovered around speakers as work approached them, and used some blankets at times...

That will be a nice touch. Thought about having my ceiling painted with glow in the dark stars. Haven't done it yet.
