RMS or Root Mean Square, as for putting dc through a speaker it WILL fry
the
coil as a speaker is only designed to take AC, to find the peak wattage of
the speaker divide the RMS by 0.707

Well that has got to be the funniest I have seen for the month.

You can be sure of one thing on this NG....... BAD AND RUBBISH ADVICE!!!!

Note: you can apply DC to a voicecoil.

IIRC RMS is not simply Peak power *0.707

Yup, this is how one of the theil small parameters is measured. They
apply DC to the coil and measure the actual mechanical force the coil
can apply.

IIRC RMS is not simply Peak power *0.707

RMS is exactly .707 * the peak voltage of a wave. Note that some
companies advertise peak power as both sides of a sine wave added together.

eg. A sub running at 800 watts peak would have 400 watts on one side of
the wave and 283 watts RMS. If a sub can take an advertised 400 watts
RMS, then technically it can take a peak to peak wattage of 1131.5 watts.

Just my $,02 of course

Exactly sqrt(2) (approximately .707), true for perfect sine
waves.

eg. A sub running at 800 watts peak would have 400 watts on one side of
the wave and 283 watts RMS. If a sub can take an advertised 400 watts
RMS, then technically it can take a peak to peak wattage of 1131.5 watts.

Oh, my! Watts RMS is nonsensical. Peak watts is nonsensical in
reality. Sure one can multiply instantaneous I*V, but it's
temperature that kills such things. Average power is of
importance (averaged over the thermal time constant of the
device).

Since you're from Greece, I don't know if you're trying to make a joke or
not.

The phrase, 'my two cents worth' (also written several other ways), is just
an expression. Much like the phrase, 'in my humble opinion', the author is
just offering his opinion. Comes from the idea that everyone has opinions,
and they usually aren't worth much (say, around two cents ;-)

P.S. Not trying to say that Keith's opinion is worthless, just explaining
the phrase ;-)
