In Reply to: New room size starting with 22ft wide?. help and advise please posted by Shane from AUS on March 3, 2007 at 03:04:06:
" am thinking about 22 by 28 by 10ft I am wary of going to big as a/. you need to drive it and b/. your bass extension goes down."RG
Power requirements have much more to do with the efficiency of the speakers, how loud you prefer your music and how close you sit to your speakers than with the size of the room.Bass extension is rarely affected by room size.
Explanation: If a room is tightly sealed like a car with the windows closed (rare) there can be significant bass ramp-up at very low frequencies (meaning a small unusually well sealed room will have deeper bass extension than a larger room when using the same speakers.Your dimensions are a little close to being multiples of one another and you may have an audible bass peak in the 45-55Hz. range. If you want a 10 foot ceiling, then other dimensions should not be close to 20 feet or 30 feet. 10' x 16' x 26' would be better.
For a 13 foot ceiling:
13' x 21' x 33' would be better.Take the smallest dimension of a rectangular room and multiply by 1.6 for the next largest dimension, and then multiply by 1.6 again for the largest dimension -- that's the best shape for sound quality assuming you want the reasonable cost of a rectangular room.
A concrete floor is not good, especially if the ceiling is also stiff -- the two opposing surfaces will cause an important standing wave bass peak about 5 Hz. wide with a center frequency in Hz. = 565/room height in feet (565/10 = 56.5Hz. for a 10 foot tall ceiling) I have this at home. You don't want it.
Your room would benefit from the most flexible ceiling possible (that is not a good bass reflector). The cement floor will be a great bass reflector. The ceiling should not be.
