What's the maths involved in working out how hard I can drive my speakers?
And what goes wrong when they're driven too hard, is it the coil rouching
the magnet?

Huge question. The maths relates to both the driver and the cabinet.
In general at the lowest frequencies overdrive will cause the
suspension to reach the end of its linear travel. This will probably
not involve hitting the magnet. At higher frequencies you generally
overheat the coil and melt the varnish holding it all together.

Thanks for that. This is the sort of stuff I'm craving after. I need a
(preferably) cheap book on these audio fundamentals. I have the Art Of
Digital Audio but as you can imagine it deals mainly with the digital domain
(good title really). But I need to know more about the important bit. That's
the audio at each end of the digital link.
