About this driver

The SB Acoustics SATORI MW19P-8 is a 7″ woofer with a free-air resonance of 29.5 Hz and a total Q (Qts) of 0.29. Its efficiency-bandwidth product (EBP) of 92 points toward either alignment. In a 12.3 L sealed box it reaches an F3 of 71.9 Hz (Qtc 0.707); a suggested 20.5 L box tuned to 41.3 Hz extends to about 47.0 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

The tweeters below pair well with the SB Acoustics SATORI MW19P-8 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.
