About this driver
The Wavecor FR090WA01 is a 3.5″ fullrange with a free-air resonance of 113 Hz and a total Q (Qts) of 0.88. Its efficiency-bandwidth product (EBP) of 110 points toward a ported alignment. In a Infinity L sealed box it reaches an F3 of 95.0 Hz (Qtc 0.707); a suggested 14.0 L box tuned to 50.9 Hz extends to about 46.0 Hz. See the sealed vs ported guide for how to choose.
