Home theater isn't just about buying the most expensive components, hooking them up altogether and getting perfect performance. There are plenty of variables that influence performance and should determine your purchasing options, and perhaps the biggest one in terms of audio is room acoustics. Check out this article titled, Why Room Acoustics Are More Important Than You Think from Christopher Klein, the director of acoustics for CinemaTech, a home theater design, furnishings and acoustics provider. He goes onto explain terms like tonal balance, imaging, and bass absorption, and how each are affected by the shape, size, surfaces and furnishings of your room (you can even now purchase noise control/soundproofing objects that look like pillows, wallpaper, artwork and other household items). This is a great beginners reference to improving home theater sound performance by taking into account your unique and particular room parameters.




Just a few quibbles:
1. Issues with corners depend on listener and speaker position. Listeners sitting in corners or near walls usually suffer from boundary reinforcement. Resonances can occur at modal frequencies, depending on speaker and listener position. Volume fluctuations are usually related to the nodes of modes, which are not found in the corners but rather at positions 1/2-way into the room, 1/4-way into the room, etc. depending on the order of the mode.
2. Imaging refers to spatial, not special, cues. Improperly controlled reflections can also result in exaggerated imaging, where each performer appears to be enormous, like ten feet wide (c.f. Bose).
