About this driver

The SB Acoustics SATORI MW19TX-8 is a woofer with a free-air resonance of 33 Hz and a total Q (Qts) of 0.33. Its efficiency-bandwidth product (EBP) of 94 points toward either alignment. In a 14.9 L sealed box it reaches an F3 of 70.7 Hz (Qtc 0.707); a suggested 27.5 L box tuned to 40.5 Hz extends to about 43.3 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

These tweeters could pair with the SB Acoustics SATORI MW19TX-8 in a two-way design, but the seed Thiele/Small data is too thin to grade the match yet — add or measure T/S (Fs, Sd, Xmax) to compute a real compatibility grade. You can still open a pair in the guided builder.

Modeled estimate from T/S + geometry — no measurements. The verdict is robust; it improves with measured FRD/ZMA data.
