What's the maths involved in working out how hard I can drive my speakers?

**Pretty darned complex. I have some computer software which can calculate
it for me in about 5 seconds. Given my computer calculates stuff at
something like 2,000 MIPS, I guess that means you'll be calculating the same
stuff, with a pocket calculator for the next couple of thousand years.

And what goes wrong when they're driven too hard, is it the coil rouching
the magnet?

**That is one possibility. There are a raft of others, including:

* The voice coil exiting the magnetic field at the front of the speaker.
* Over-heated voice coils.
* Damaged sections of the cone, where it meets the voice coil former.
