it is SOO Much harder to find a sub that will sound good with music than movies..

Case and point. my KLH 100 dollar 10 inch 120 watt sub. costco special. music it blows chunks like nothin you have ever seen.

For movies. it still does. lol but not as bad. Its more like the theater subs. I watched pirates of carribean lastnight and i honestly thought i was gonna blow the sub a couple of times but it held up. it doesnt go real deep and its not real controlled but it sure booms.
