About this driver

The Faital Pro 12PR320 is a 13″ 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.

modeled estimate

The tweeters below pair well with the Faital Pro 12PR320 in a two-way design — each grade is a modeled estimate of the crossover match, with a suggested crossover point. Open any pair in the guided builder to design the crossover and total the parts.

Modeled estimate from T/S + geometry — no measurements. The verdict is robust; it improves with measured FRD/ZMA data.
