About this driver
The Faital Pro 6PR150 is a 6.5″ midwoofer with a free-air resonance of 100 Hz and a total Q (Qts) of 0.34. Its efficiency-bandwidth product (EBP) of 286 points toward a ported alignment. In a 1.5 L sealed box it reaches an F3 of 208.0 Hz (Qtc 0.707); a suggested 2.8 L box tuned to 119.1 Hz extends to about 125.5 Hz. See the sealed vs ported guide for how to choose.
