About this driver
The Faital Pro 5FE120 is a 5″ midwoofer with a free-air resonance of 65 Hz and a total Q (Qts) of 0.48. Its efficiency-bandwidth product (EBP) of 127 points toward a ported alignment. In a 4.6 L sealed box it reaches an F3 of 95.8 Hz (Qtc 0.707); a suggested 9.6 L box tuned to 54.4 Hz extends to about 49.4 Hz. See the sealed vs ported guide for how to choose.
