Depends on the speaker. Some are designed for sealed boxes, some for
ported. Check the specs.

OK. Thought it over. I had always assumed that the reccommended box
was to do with sound characteristics, not the ddanger of blowing
cones. This has always been born out for me by the fact that some
speakers just sound like **** in a vented/closed etc enclosure.

I've also seen speakers blown the way you describe, but it had nothing
to do with the box. A subsonic noise component drove them right out
of the baskets. G

Popping the cone...no that has another meaning altogether, IIRC.

It would have _something to do with the box, surely. The back-pressure
in a sealed enclosure _may_ have saved that one time.

I do remember that stage speakers have a completely different
magnet/coil setup, so that the coil moves out of the magnetic field
before the coil pops out of the basket.

Stage speaker drivers are, as a rule are a good bit less efficient than
home speakers. Recorded music is massaged and compressed, and never has
things like 120dB accidental feedback, not to mention live uncompressed
drums.

If you connect your 1200W stage stack to your home receiver, you'll be
impressed by how little volume you get, and how muddy it sounds (to be
pedantic, you'd usually need a passive crossover to do this).

OTOH, if you connect your "100W Peak Power" home stereo speakers to an
inexpensive 50W guitar amp, you'll be impressed at the bright colors and
the smell of the smoke.
