About this driver
The SB Acoustics SATORI MW13PNW-8 is a 4.5″ fullrange with a free-air resonance of 41 Hz and a total Q (Qts) of 0.31. Its efficiency-bandwidth product (EBP) of 124 points toward a ported alignment. In a 3.6 L sealed box it reaches an F3 of 93.5 Hz (Qtc 0.707); a suggested 6.3 L box tuned to 53.7 Hz extends to about 59.1 Hz. See the sealed vs ported guide for how to choose.
