THe Metallica song One has a LOT of bass in it, I noticed my sub was clipping bad, turned it down and noticed the M80 was distorting a bit as well, I had it cranked up really loud (maybe 100db area?), pushing with Outlaw M2200, anyone else that likes that particular Metallica song notice that when they have their system cranked?
Actually I think it might be the mids that are clipping when Lars hits the bass drum...
