Please help: Room size?

Hi,
I'm going to build a room for hometheater and music in the next two weeks. However, I'm having problem to decide the room length. The new room will be 8'H x 10'W x 17' to 22' in length.
The room will be in rectangular shape, and I can't change the height and width of the room. If I go with 22' length, I'll save a lot of money because I don't have to modify the room a lot.
So, will 22'L x 10'W x 8'H be ok? What's kind of problems should I expect with the sound (base problem???)and is there anyway to fix the problems? Please help.
Thank you very much.

Hi,
I have a JM Lab 926 floors standing speakers that can go down to 35Hz.
Like Sean said, I'll make the room 22' but I'll build a entertainment center that is 2' deep plus 2' free space on the back of the entertainment center. So, my new room will be 18'L x 10'W x 8.5'H.
Do you think the new dimension is ok? How far should I put the main speaker from the entertainment center, and from the sidewall? I need to know roughly where to put the main speaker so that I can decide where to place the main door that won't hit the speaker when I open it.
Thank you very much.

I'm not familiar with your particular speakers. With that said, I usually prefer speakers set up along the long wall. While moving your entertainment center back from the main wall will probably help soundstage due to early center side reflection elimination, having an open cubby may(?) effect inroom bass response. Videophiles usually recommend bringing the monitor (standard) out from the back wall and having some soft light reflecting off the back wall behind the video monitor. Our eyes were designed to see reflected light not direct light, so this will ease eye strain. The area behind the monitor (and ideally the whole room) should be a neutral grey color to avoid apparent color abberations. Am I correct in assuming that you are planning on a two channel home theatre sound system?

Hi,
Should I do a this kind of sloped ceiling? The room will be no slope for 8' long and then it starts to slope for the rest of 14' long (8' is the lowest and 9' is the highest).
Like I said, my new room will be 22'L x 10'W. For the non slope session, the media center is 2' deep and I leave 2' open space behind the media center. I plan to place my speaker 4' from the media center. So, the main speakers will be placed right on the place where the ceiling starting to slope.
Is this safe with this kind of slope? or should I go all like normal with 8' ceiling height for the whole room?
Please help. Thank you very much. DT
