how to use low watt speaker with high watt amplifer

[Rich Grise]

thx. from your comments i found an idea. i will try put a resistor in
series and add a switch parallel to it to disable it so when i need
more volume i can get it by turning the switch on.

OK - if you're taking a survey, put me down in the "Yeah - do this"
column. ;-)

Cheers!

I just have a hard time believing the motion cooling is significant...

It is.

It looks like the voice coil is just buzzing around in it's own hot
air. The circulation is not like a fan.

High power speakers have specially vented magnets.

It's probably why somebody made ferrofluid speakers..

That helps the heat transfer to the magnet assembly.

I guess the OP never held his hand over the VC vent of an active high
power speaker. The air movement is very considerable.

Gee..maybe I can turn off my ceiling fan and just crank up my music
instead..

I'd like to think there's a difference between vibrating air and
moving air..

I'm guessing the only way for cooler air to mix with the hotter
vibrating air around the voice coil is from the chaotic air turbulence
surrounding the speaker.

I've seen very high power speakers for sound reinforcement that use forced air cooling of the
voice coil. There's a large flexible tube providing 'compressed air' to the rear of the magnet
assembly.
