The overall room ratio is the critical element and the problem with a low ceiling height is that it limits the number of practical room ratios. Low ceilings also create the possibility of greater frequency response irregularities due to reflection cancellation effects. These are not fatal problems, but they do require increased effort in speaker placement and/or corrective acoustic treatments.
Ceiling Height
In terms of sonic importance, how vital is room ceiling height? My listening room is a converted basement, and the ceilings are only 7'. Is this normally a disadvantage? If so, what is optimal? Does extra ceiling height confer any sonic advantage? Sorry for the silly question, but this is an area of room setup that I don't understand very well. TIA.
