My subwoofer is located 7 feet from my seating position. Using Avia, my LFE level is properly set. I've run into problems when trying to match the sub with the crossover frequency (80hz) of the front mains. If I set my subwoofer distance within the AVR to 10 feet, I get a perfect match between high frequency, crossover, and LFE (when factoring in correction) tones with the AVIA test tones. If I set my subwoofer distance to 13 feet, I get maximum SPL at the crossover frequency, which rises ~4db (so instead of 75db, its ~79db).
I'm a little confused because I've read that the subwoofer is in phase with the mains when it produces its maximum SPL; am I doing the wrong thing setting the distance at 10 feet to keep things equalized?
