About this driver
The FaitalPRO 12PR320 is a 12″ woofer with a free-air resonance of 42 Hz and a total Q (Qts) of 0.37. Its efficiency-bandwidth product (EBP) of 108 points toward a ported alignment. In a 42.7 L sealed box it reaches an F3 of 80.3 Hz (Qtc 0.707); a suggested 85.2 L box tuned to 45.9 Hz extends to about 46.5 Hz. See the sealed vs ported guide for how to choose.
