Rleff, well with some I really don't remember. My Infinity ServoStatics had a feedback subwoofer, which may have been larger than 12". It was, of course, really a woofer, but it never really mated with the electrostatic panels. The second was an Epps 12" isobarik design that was 8' tall. I had 800 watts per side on it but perhaps not a great crossover. I used it with the Soundlabs A1s.
Most of my experience was with using subs with horns. Again with my Beauhorns, I used the Epps with no greater success. I should say that I could shake the house with the Epps.
I am trying a Zu Methods with my dynamic Tidal speakers, but I have yet to get it working. I will crossover at 40 Hz.
What bothers me is that the subwoofer seems like a separate speaker playing music. This may be the slope of the crossover, of course.
