About this driver
The Dayton Audio E150HE-44 is a 5.5″ woofer with a free-air resonance of 40 Hz and a total Q (Qts) of 0.39. Its efficiency-bandwidth product (EBP) of 89 points toward either alignment. In a 3.3 L sealed box it reaches an F3 of 72.5 Hz (Qtc 0.707); a suggested 6.8 L box tuned to 41.4 Hz extends to about 41.0 Hz. See the sealed vs ported guide for how to choose.
