Nrchy: The overall dimensions are approximately 25 x 20 x 7. With a little treatment (bass traps, Echo Buster panels, etc.), the room actually sounds pretty well balanced--there don't seem to be any glaringly obvious problems--but I'm not sure if the dimensions fit the "golden ratio," or whatever they call it.
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.
