About this driver

The Eminence KAPPALITE-3015LF is a 16.5″ woofer with a free-air resonance of 44 Hz and a total Q (Qts) of 0.46. Its efficiency-bandwidth product (EBP) of 92 points toward either alignment. In a 110.8 L sealed box it reaches an F3 of 67.6 Hz (Qtc 0.707); a suggested 232.8 L box tuned to 38.5 Hz extends to about 35.5 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

The tweeters below pair well with the Eminence KAPPALITE-3015LF 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.
