Home Theater Room Size and Configuration
The size and configuration of your home theater room have more of an impact on the sound quality of your than you might think. Those that take this into consideration as they lay out their design concept will ultimately get the most out of their sound system.
Cutting through all the acoustical science, empirical information, and technical jargon, you should simply avoid building your theater in a sqaure-shaped room (considering the height, as well). The guiding principle among home theater professionals is to structure the dimensions of your room in such a way that its width, length, and height measurements do not share a common denominator. For example, a room with the dimensions of 15W x 11L x 8H is preferable to a room 16W x 12L x 8H (all evenly divisible by 4). Doing this will minimize the phenomena known as standing sound waves, which has a degrading effect on the performance of your sounds system.
If you're constrained by the space you're working with, meaning you don't have a whole lot of flexibility in the room's shape or dimensions, you shouldn't worry too much about the configuration of the room. However, you do want to make sure that the sound system you're using is adequate for the size your room. Obviousbly, the larger the room the more powerful and/or higher quantity of speakers you will want to use.
For those of you intend on really getting into the deeper technical aspects of your home theater room's configuration, you need to understand that seating and the room's layout are interdependent. The size and shape of the seating you'll be using will impact the dimensions of the room and vice versa. Additionally, this also impacts the optimal positioning of your speakers in your room.
