Axiom Home Page Forums General Discussion Technical Questions EP500 Not working

The reason class AB amps have to be big and heavy, because one that draws 600 Watts from the wall will be dissipating over 300 of it as heat. Where as a 600 Watt class D, can turn 90% of that draw into sound, and only have a fraction of the heat to deal with.

I'm just speaking in general terms, having never seen nor heard any version of Axiom's subs.
