Gonna be starting construction in a couple months and heres what I have. Right now my design is allowing for a room 22x19 with a 10 foot ceiling. Would this be good demensions for sound quality? I figure I'll drop the ceiling down about a foot or 2 with those ceiling tiles they use in office buildings. Will those have much affect on the sound at all? The 22' is unchangable but I could adjust the 19' to be smaller if there is a more ideal size. Let me know what you think.



Also, right next to the theater will be a small room that I am calling control room. Basically to house all the video equiptment. So in my theater there are 2 doors on the same wall, one is the entrance and one is the control room. These 2 doors are on the side of the theater. Doors shouldn't effect sound much right?



Last question, my room will have no windows. YAY!!!! But I feel like I should have another exit, an emergency exit. I think the inspector will enforce that. So, my options. Would you put a door that exits to the outside? Or should I have another exit that exits another part of the house.




Thanks for your opionions!

I'd leave it at 22' x 19' x 10'.

I tried that, and 18.5', 18', 17.5', 17' at http://www.bobgolds.com/Mode/RoomModes.htm and all were worse than 19'.

You can go as far as to have the entire 2 feet full with two layers of R30 (9.5" each, so 19" of fiberglass), or even rigid rockwool. Combined with a reflective floor (wood, tile) that will give lots of balanced absorbtion down to very low frequencies. This sort of thing needs some more thought about sound paths.

Left/right symmetry is desireable. I take it your 'control room', is not a projection booth.

If you want another exit, then put one in. Around here a window is required for fresh air for any 'dwelling unit' which is defined as a bedroom, and there are hallway and such requirements in the fire code. Once it is obviously not a bedroom, I can do what I want.

Leave as much ceiling height as you can. I wish mine was 10'.

Ditto to what bpape said. I have an 8' ceiling and when tall (6'0" or over) people stand on my riser (11") it puts them close enough to the ceiling that they instinctively "duck".

Thanks for the replies! Heres a rough drawing of the the floor plan so you can visualize. I'll be using a digital projector connected to a HTPC which will be in a seperate room called the control room. I think I'm going to put an exit in the control room which goes directly outside. Unless the inspector says I can't, we'll see. Let me know what you think and if theres any reason why this design will suck!

(not sure why this comes up as a link instead of an image)


I also have an electrical question. When I have it wired up for electricity what should I tell the electrian to do? I figured the theater and control room would be a seperate circuit than anything else. Will this be ok or should I have multiple circuits, 1 for amps, 1 for lights, etc.


Any other tips? I just don't wanna get done some day and say CRAP! Why did I do it this way!?!?!?! :D
