About this driver
The Dayton Audio PS180-8 is a 6.5″ fullrange with a free-air resonance of 58.5 Hz and a total Q (Qts) of 0.33. Its efficiency-bandwidth product (EBP) of 163 points toward a ported alignment. In a 7.7 L sealed box it reaches an F3 of 125.4 Hz (Qtc 0.707); a suggested 14.2 L box tuned to 71.8 Hz extends to about 76.8 Hz. See the sealed vs ported guide for how to choose.
