About this driver
The Wavecor FR090WA02 is a 3.5″ fullrange with a free-air resonance of 114 Hz and a total Q (Qts) of 1.04. Its efficiency-bandwidth product (EBP) of 90 points toward either alignment. In a Infinity L sealed box it reaches an F3 of 88.1 Hz (Qtc 0.707); a suggested 24.4 L box tuned to 43.3 Hz extends to about 40.6 Hz. See the sealed vs ported guide for how to choose.
