About this driver
The Dayton Audio PS65LP-4 is a 6″ fullrange with a free-air resonance of 67.3 Hz and a total Q (Qts) of 0.24. Its efficiency-bandwidth product (EBP) of 259 points toward a ported alignment. In a 2.3 L sealed box it reaches an F3 of 198.3 Hz (Qtc 0.707); a suggested 3.1 L box tuned to 114.5 Hz extends to about 142.6 Hz. See the sealed vs ported guide for how to choose.
