I know it can't be true, but it seems that way. while the dayton was boomy, I could at least here it. not so with the infinity. I almost have to turn the gain to 100% to hear anything. setup: I have an onkyo 602, and the sub is hooked up with a y-connector. dayton: the dayton's gain was at about 12:30, and the sub level on the receiver was 0. when I did the auto calibration, the sub was set at -2. infinity: the gain is at about 1, and the receiver's auto setup set it at 9. I set it back to 5, because that seemed too high. it is set on lfe, with phase at 0. the sub's are in the same spot, and the crossover is on 100% for each. I'm crossing over at 80 hz. please help!
