Hi all, I am planning an home theater in a dedicated room that will be built on purpose (7x5m / 21x15'); I've read lot of things about acoustics and acoustic treatment, but usually suited for stereo systems. Well, I think that corners lower frequencies treatment (for reducing room resonance problems) should be the same, but I would like to know if there are specific rules for home theaters, first of all if for main reflection case are more appropriate absorbing devices (like perforated panels and tube traps) or diffuser devices (quadratic residue / diffractal, rpg). Anyone can tell me where to find information or if subsist some specific/requirements just for home theaters? I look for this on the forum but I couldn't find it, I hope to have not written about an already discussed topic. Many thanks, regards.
