About this driver

The Tang Band W5-1880 is a 5.5″ fullrange with a free-air resonance of 48 Hz and a total Q (Qts) of 0.32. Its efficiency-bandwidth product (EBP) of 126 points toward a ported alignment. In a 6.8 L sealed box it reaches an F3 of 106.1 Hz (Qtc 0.707); a suggested 12.3 L box tuned to 60.8 Hz extends to about 65.9 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

The tweeters below pair well with the Tang Band W5-1880 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.
