Hi Lord Valve, I just started reading Daniel Levitin's book, "This is
Your Brain on Music" and in the introduction he says that in his
college days he listened to music at such high volumes that: "I
actually set my loudspeakers on fire by cranking the volume too high."
Is this hyperbole, or can this really happen? Thanks.
Yes, in fact, loudspeakers can catch fire with very heavy use.
It's not common for this to happen with home-type speakers,
though, because the amps typically used with them usually
don't have enough power to heat the speaker voice coils
to red heat. Pro rigs, however, often incorporate amplifiers
of several thousand watts, and a red-hot voice coil can
ignite the paper cone of the speaker. This was much more
common in the old days, when most voice coil formers
(the hollow tube the voice coil is wound on) were made
from paper. Nowadays, voice coil formers are made
from Kevlar or other high-temperature materials (including
aluminum) and it's rare for an open flame to result, although
much smoke can be emitted. Don't ask how I know this. ;-)
