About this driver

The Dayton Audio DC130B-8 is a 5.5″ woofer with a free-air resonance of 52.5 Hz and a total Q (Qts) of 0.38. Its efficiency-bandwidth product (EBP) of 109 points toward a ported alignment. In a 5.0 L sealed box it reaches an F3 of 97.7 Hz (Qtc 0.707); a suggested 10.2 L box tuned to 55.8 Hz extends to about 55.9 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

The tweeters below pair well with the Dayton Audio DC130B-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.
