Last night I wrote that the MVW system "probably has poor time domain performance". After talking with Steve, Tom's co-inventor, I think that was probably a mis-characterization. I was thinking of the apparently de-correlated contribution from the bells arriving after some time delay.
Unlike a system based on a resonance, and in particular a Helmholtz resonance, the MVW enclosure loses energy very quickly when it is no longer being actively energized by the movement of the cone (and the cone in turn is moving in response to the signal from the amplifier). The MVW enclosure wants to quickly go to its rest state, rather than finding equilibrium in a resonant state that decays slowly, so at low frequencies it doesn't keep on singing after the amplifier has stopped telling it to. And that might well explain the quick stops.
