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.

modeled estimate

The tweeters below pair well with the Dayton Audio PS180-8 in a two-way design — each grade is a modeled estimate of the crossover match, with a suggested crossover point. Open any pair in the guided builder to design the crossover and total the parts.

Modeled estimate from T/S + geometry — no measurements. The verdict is robust; it improves with measured FRD/ZMA data.
