I've seen conflicting information about whether or not YPAO will eq a subwoofer with fierce room modes, or whether I should use a Behringer FDP type box to sort it out. I've been running an integrated amplifier with no line level sub out, and am moving up to a Yahama RX-V667 that provides subwoofer line output. Does the YPAO have enough eq points to tune the sub, or should I add a box inline?
