About this driver

The Wavecor FR070WA02 is a 2.5″ fullrange with a free-air resonance of 124 Hz and a total Q (Qts) of 0.69. Its efficiency-bandwidth product (EBP) of 170 points toward a ported alignment. In a 10.8 L sealed box it reaches an F3 of 127.1 Hz (Qtc 0.707); a suggested 3.2 L box tuned to 71.6 Hz extends to about 62.3 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

The tweeters below pair well with the Wavecor FR070WA02 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.
