Yeah, Byrd, my Monitor 4's with Mike Savuto's servo rebuilds have tons of slam by themselves. They don't punch you in the chest on bass notes the way big dynamic drivers do, but I'm not so sure that's the way music really sounds anyway. Never once at the symphony did the music punch me in the chest. Anyway, to assume ESL's don't have slam is a mistake.

Drums are dipoles and it may be that the way a dynamic woofer pressurizes the room just isn't realistic. OTOH, there's something to be said for the sheer ability of a large dynamic woofer to play loud. I don't know of any planar that can match it, though the largest can outpunch some smaller dynamics. That said, the Acoustats play louder than most stats and so are a partial exception to the rule (I don't know of any planars that will do the 120 dB+ that's necessary to reproduce the full dynamic range of acoustical music).

And the strange thing is he only listens to clavichord music. :-)
And needless to say ten Prostats/eight Pass' might be useful if one is using Carnegie Hall as their listening room.
It's a bit big for my listening room, I'll admit. :-)
...since vertical dispersion for the loge is limited by panel height. :)
Maybe musicians should be seated up there rather than gutting the interior of David Geffen Hall, problems solved.
the big Maggies can get deep and loud; all it takes is high current and sustainable power. I had my room rocking over the weekend, window rattlin' and curtain rods a'shakin with the below video.Bi-amping is the way to go; something nice and soft on top along with brute force on the bottom!
I was jamming this over the weekend, lots of bass along with dynamics to boot. Hey it also gives me an opportunity to show off my DIY interconnect skills (Cardas/Belden/Jon Risch design); and yes I know I need shelves ;).
I'm a firm believer the medium to large Maggies can reproduce ANY natural musical instrument with ease; including kettle drums :)
I don't know the name of the song, I borrowed it from a friend and Shazam can't identify it either.

That's why I have Tympanis. :-)
The mids on the 20.1 and more so the 20.7 are a limit in that regard since they tear if pushed above 115 db peak, But 115db is good enough at home. I was surprised by the fact that I actually had headroom over that.
Well, I have no way to verify the accuracy of the dB app download on my iPad, but 112 is the loudest I could stand from my Acoustats. BTW, the preamp had gain left to go. How much I don't know, I couldn't stand past that point.
Here are the specs from the Stereophile reviews:
Description: Full-range electrostatic loudspeaker. Frequency response: 28Hz-20kHz ±2dB. Nominal impedance: 4 ohms. Power capability: 500W. Maximum output: 115dB at 20' in a 16'x24' room. Minimum power requirement: 50Wpc. AC power consumption: 5W.
So they really should do a bit better than 115 dB at a more realistic listening distance.
My Monitor 4s are driven with OTL direct drive tubed servos. I think those electrical specs you quoted might be for the transformer interfaces?

I'm sure they are. Not sure how hard the OTL's can drive them.
I think they are. IIRC someone guesstimated that the servo amp acoustats had 3db more sensitivity but I don;t know that the amp can actually output that much to make use of the driver's greater headroom without the transformer.
