woofer response
The PC 15 woofer offers the best performance/box size compromise using a 3.0 cubic
foot Vented box. The Sealed box pushes the -3dB frequency above 50 Hz but an Infinite
Baffle (trunk installation using the rear deck or back of the rear seats) can offer
tremendous results simply due to the pressurization of the car’s interior from so much
woofer cone area and movement.
A Single-Vented
box approaching 6.0 cubic feet must be constructed to provide
e -3dB frequency similar to a Vented design. The advantage with the
design
‘its tremendous power handling potential (200 watts +
l
(Parameter values may deviate slightly in production units but the perceived performance variations will be negligible
