I was always wondering why the back plate on the amp was always warm 24/7. I had discussed this with other people who had found out from Paradigm directly that this was normal. Back in Feb 04 I paid $1050 CAN.
The sort of boomy experience you had I could replicate easily in my room. Using bass management, a SPL meter, and a little crawling around for bass to find an optimal location for the sub, whola.....no more boom.
