Twin subs is a very good idea. I've been a fan for many years, after my audio mentor pointed me to the Harman paper on the subject. Even before that, I quite liked the idea, mostly because far too many people were partnering micro-monitors with a single sub in the farfield; the main units couldn't get down low enough for them to sum properly, so stereo imaging was compromised in the midbass region. And there's a goodly history to stereo subs -look at the Rodgers AB1, intended to partner the LS3/5a & be used as a stand if desired.

Qtc = 0.85 (just under 1/2dB peaking at Fb)

Fb = 47.5Hz

F3 = 41Hz

SPL = 83.5dB 1m/2.83v, or 80.7dB 1m/w depending on which rating you use. The latter is the efficiency rating, the former the real-world sensitivity so I always suggest the 2.83v value is used as it's consistent across all coil impedances, since voltage is fixed & the driver simply draws what current it needs from the amplifier. Excursion is roughly 1mm for this value.

That's not bad for a small box.
