It'd be like trying to blow an engine by not supplying enough petrol to it.

But if the underpowered amplifier was then substituted with a more powerful model, the drivers would have the potential to be pushed beyond what the previously clipped was ever capable of doing. But meh, the least of concern really.

Back on topic, so what's wrong with clipping?

Well aside from sounding like absolute shit, this now totally distorted signal features completely altered upper harmonic content, with way more energy than ever before (which is why the distortion can be heard clearly above the music) and it's this savage new waveform that fries midrange / tweeter drivers.

I beg to differ.

A clipped signal is like applying constant DC to the voice coil, which it is not designed to do - even if it is a long way under full excursion. This is why it's good practice to always run your amps at full.
