Axiom Home Page Forums General Discussion Technical Questions Subwoofer calibration.

You could try moving your mic a little when doing the auto calibration. It could be in a dead spot where all the bass cancels out and the mic doesn't actually hear it at all, even though your walls are shaking apart. So the receiver just keeps cranking up the gain hoping to hear it eventually but never does, so it just leaves it maxed out. Just an idea you can try out.
