| Re: What would be the perfect size and shape of a new HT room?
Actually, the ratio you pick isn’t that bad. Regardless of what ratio you pick, most likely the space will still be too small to achieve proper axial-mode spacing. The goal is to design for as uniform mode spacing as possible (modes not spaced too far apart or too close together) and to try and avoid mode coincidences (mode resonances piled up at the same frequency). Now with that said, ratio 1 X 1.6 X 2.33 with a height of 10’ has the following problem areas:
Two modes resonances occur very close together at about 65 Hz, then again at about 140 Hz, and last somewhere around 240 Hz. There are two mode coincidence (two mode resonances pile up); one at about 165 Hz and another at about 280 Hz (but this is pretty high and most likely could be addressed fairly easy).
Hope this help… For what it’s worth, the ratio you picked is most likely the ratio I will shoot for some day when I am able to build a dedicated theater space.
