orig. quoted by Havasu Hangin:
A clipped signal cannot generate more heat to the speaker...only overexcursion can, which is usually caused by overdriving (past the speaker's rating). Overexcursion causes heat, which kills voice coils.
Any time the wave get to large the wave clips this creates constant output "dc voltage" speaker coil connot collapse, stays at full throw, coil cannot cycle, coil gets hot, welds. If I'm wrong please do explain.
