About this driver

The Dayton Audio PA130-8 is a 5″ fullrange with a free-air resonance of 83.4 Hz and a total Q (Qts) of 0.51. Its efficiency-bandwidth product (EBP) of 139 points toward a ported alignment. In a 4.3 L sealed box it reaches an F3 of 115.6 Hz (Qtc 0.707); a suggested 8.6 L box tuned to 65.6 Hz extends to about 58.5 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

The tweeters below pair well with the Dayton Audio PA130-8 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.
