magnet

what role does the magnet play in the subwoofer bigger the better etc?

kind of has to do with power... its not a linear, exponential or otherwise thing since there's different kinds of power handling... thermal is one kind of power rating, i forget the others though

The magnet is your driver, what you do when you make sound is you run power acros a coil thus creating an electromagnit. Now based on the polatiry at the point in wavelength, you electromagnet will with be repelled by or attrated to the bigger magnet. An thus you get vibrations and sound.

What i was about to say...

depends. different companies uses magnets for various reasons.

ie)
B&W for actual purposes
Audiobahn for marketing

These days magnet sizes don't play the role as the major used to. With growing technological advancements subs and speakers are made so efficient that size doesn't matter anymore. Well not as much as before. Actually lighter is better in recent sub development. But the use of magnets will still be needed.

Physics 101: A magnet has the ability to attract or push metals based on polarity. Apply that property with the aid of electromagnitism to "push" and "pull" a speaker cone, the result is moving air (sounds waves).

My favourite site does a great job of illustrating this
