Well I finally got my Radio Shack SPL meter and used it with my Avia disc and all is well except that my right front speaker is 3db louder than the rest of my speakers. There is no way to adjust the level of that speaker alone with my receiver (a panny HE-100). The right speaker is basically in a corner while the left speaker is not. Could this account for the difference? If so (other than moving the speaker which is not possible) what can I do to balance it with the rest of the speakers?
