About this driver

The Eminence OMEGA-PRO-15A is a 16″ woofer with a free-air resonance of 33 Hz and a total Q (Qts) of 0.32. Its efficiency-bandwidth product (EBP) of 100 points toward either alignment. In a 66.6 L sealed box it reaches an F3 of 72.9 Hz (Qtc 0.707); a suggested 120.4 L box tuned to 41.8 Hz extends to about 45.3 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

The tweeters below pair well with the Eminence OMEGA-PRO-15A 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.
