Loudspeaker power capacities

Loudspeaker manufacturers publish power ratings for their systems, but you can also estimate the appropriate amp power
by measuring the woofer's voice coil diameter. Loudspeaker drivers with larger voice coils can generally handle higher
power than those with smaller ones. The dust cap in the center of the cone may or may not be the same diameter as the
voice coil; consult the manufacturer's spec sheet to be sure.
