About this driver

The Tang Band W2-1767S is a 2″ woofer with a free-air resonance of 110 Hz and a total Q (Qts) of 0.36. Its efficiency-bandwidth product (EBP) of 268 points toward a ported alignment. In a 0.1 L sealed box it reaches an F3 of 216.1 Hz (Qtc 0.707); a suggested 0.2 L box tuned to 123.6 Hz extends to about 126.8 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

The tweeters below pair well with the Tang Band W2-1767S 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.
