About this driver
The SB Acoustics SATORI MW19PNW-4 is a 7″ woofer with a free-air resonance of 29 Hz and a total Q (Qts) of 0.24. Its efficiency-bandwidth product (EBP) of 112 points toward a ported alignment. In a 7.9 L sealed box it reaches an F3 of 85.4 Hz (Qtc 0.707); a suggested 11.0 L box tuned to 49.3 Hz extends to about 61.4 Hz. See the sealed vs ported guide for how to choose.
