I did a search, and got more confused as I read. So, I need a clarification: Using my receivers test tones, I used my Rat Shack SPL meter to get 75dB all around, including the subwoofer. Having read about LFE +10dB boosts and such, I've realised that I may have set my sub 10dB too low. Did I? Should I adjust my sub to 75dB or 85dB? I want 2 channel music to be "right"... EDIT: FYI, my speakers are all set to small... Thanks, Martin.
