My room is 10.5x40x7 (1 Viewer)

[Mickey Brown]

I'm finishing up the basement for a nice place to watch movies and listen to music. With my room being a huge rectangle, I'm wondering if I should drywall half of it off.

Anyone have a very long room? I imagine that sonically it would have to be better than the hugely open spaced room I have now.

btw, the room is 11 ft by 40 ft...

7 feet high

11' X 40' !?! Wow... personally, I would look into building a bowling alley down there.
Well, if you want to split up standing frequencies as much as possible... I would wall it off to the Golden Mean (1:1.618) at about 11' X 17'. But, that doesn't leave you much space.
If that's too small, you could go 11' X 27.5' (1:2.5)
Or, you could just go with whatever size you want and add acoustic treatments after the fact.

Mickey,

I agree with the use of the golden mean.

I took it one step further and ran these dimensions in RPG's room optimizer. Here are your results (assuming you are using this space for a 5 channel system with dipole surrounds)

Listener and Loudspeaker cordinates:

Listener position(10'10.3",5'6",3'8.9")

Front stereo left(4'6.8",8'2",1'9")

Dipole surround left(10'10.3",4'6")

Front stereo right(4'6.8",9',1'.9")

Center front(3'7.9",5'6",1'9")

Dipole surround right(10'10.3",10'8",6')

Subwoofer placement(assuming location is to be constrained to the front wall area:

subwoofer (2'2.1",9'4.5",2'2.9")
