I killed the coils on a couple 12" Cadence beasts, appearently they don't like 1400 watts and sealed enclosures too much. buried at the dump.
I also killed a Sony explode 6x9 with a 1200 watt class D amp "by accident" //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif thown out window at high speed
A 12" Infinity perfect suffered from voice coil seperation while under my care, but it was due to a manufacturing flaw. replaced under waranty
A 10" Urban audio works sub suffered a drowning accident when a full bottle of beer was poured on it while playing full blast. gutted for use as a fridge magnet
A Concept SS 12" had a spider failure due to a manufacturing defect with the first run units. replaced under warranty
Thats it for my graveyard over the past 10 years.
