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.
