About this driver

The Dayton Audio PN395-8 is a 16.5″ woofer with a free-air resonance of 44.1 Hz and a total Q (Qts) of 0.35. Its efficiency-bandwidth product (EBP) of 123 points toward a ported alignment. In a 31.4 L sealed box it reaches an F3 of 89.1 Hz (Qtc 0.707); a suggested 60.6 L box tuned to 51.0 Hz extends to about 53.0 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

The tweeters below pair well with the Dayton Audio PN395-8 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.
