About this driver
The Faital Pro 4FE35 is a 4″ fullrange with a free-air resonance of 100 Hz and a total Q (Qts) of 0.83. Its efficiency-bandwidth product (EBP) of 96 points toward either alignment. In a Infinity L sealed box it reaches an F3 of 87.3 Hz (Qtc 0.707); a suggested 26.0 L box tuned to 47.8 Hz extends to about 42.8 Hz. See the sealed vs ported guide for how to choose.
