This is not directly related to my Axioms, but is of course a part of the whole package.

I have a complete Axiom package minus the SubWoofer. I got myself an SVS-20-39-PCPlus. I watched Return of the King last night. There was a scene where a Ring Wraith landed on the wall in front of Ghandalf during the battle. The bass from the winged beast was unreal. Unfortunately I heard a VERY loud pop from the subwoofer. My sub had never put out levels like this before and I may have had it turned up too high. Is there any way for me to test how much I may have damaged my sub?

Also, the friend that was demoing my system with me said something about the settings being wrong. He mentioned the volume had to be turned up very loud to hear the bass. I had the Gain at 80% max and the receiver volume at -12. Any idea what setting i may need to check on the receiver to correct this?
