Regarding ideal room dimensions, i found an extract from a book by James Mair: "High Quality Sound Reproduction" where he recommends that room dimensions not be multiples of one another; he gives examples of room dimensions that will evenly distribute room resonances:
small room: 1 x 1.25 x 1.6
medium room: 1 x 1.6 x 2.5
large room: 1 x 1.25 x 3.2
there is also a good site on the net:
http://www.acoustics.salford.ac.uk/acoustics_info/room_sizing/?content=indexwhere it says:Louden [3] calculated the modal distribution for a large number of room ratios and published a list of preferred dimensions based on the standard deviation of the intermode spacing to achieve evenly spaced modes. The method produces the well known room ratio of 1:1.4:1.9.
hope this helps. :-)
