The Whispering Gallery

Generally, when I listen to music I listen without a subwoofer and just my two front speakers using the Pure Direct setting on my receiver. When I sit in my preferred listening spot in this 2.0 (two speakers, no sub) configuration, the bass guitar sometimes sounds like it's coming from behind my right shoulder. What I am experiencing is a standing wave at certain frequencies that is "piling up" in the space where I imagine the sound is coming from. This is due to a sympathetic resonant frequency (that increases the SPL of the sound wave). If my room dimensions were even a few inches different, or if I moved any of the furniture in the room even a little, this standing wave would disappear (or in reality, move elsewhere).

I talked about standing waves and how they can mess up an otherwise awesome home theater system last summer but there's another type of standing wave phenomena that occurs simply as a result of architectural design.

This is awesome, thanks so much for this. I've experienced this many places, but related to KEF, with the LS-50 many times!
