About this driver
The Dayton Audio PA165-8 is a 6″ midwoofer with a free-air resonance of 80.8 Hz and a total Q (Qts) of 0.47. Its efficiency-bandwidth product (EBP) of 135 points toward a ported alignment. In a 7.3 L sealed box it reaches an F3 of 121.6 Hz (Qtc 0.707); a suggested 15.2 L box tuned to 69.1 Hz extends to about 63.3 Hz. See the sealed vs ported guide for how to choose.
