Why is it that lower frequencies are known to blow audio speakers seeing
that higher
frequencies produce more energy RMS?
What actually blows the amplifiers?
Thanks
First of all, your ears are less sensitive to low
frequencies (they are most sensitive around
1k-4k, falling off above and below that). And
since many folks like gut-thumping bass,
there can be a lot of watts involved before
your ears complain.
But second of all, your statement isn't
always the case. In pro sound systems
(nightclubs, etc) which are cranked up a
lot, it's often the tweeters that give out
first. This typically happens from overdriving
the amp so that it clips. The signal that is
causing the clipping is typically low frequency
(those gut-thumping bass lines) but the
clipping distortion is much higher and goes
to the tweeters. Since tweeters are typically
rated for much lower power than the woofers
in a system (due to normal hearing sensitivity),
they can't handle the power due to clipping
and blow out.
