The OP said "no stored woofer energy." :)
But, I disagree that it's "very little." As I suggested earlier.....excite the woofer with an impulse and monitor via oscilloscope and close microphone. If you call that "very little stored energy" then I think you need to re-adjust your reference. :)
The reason these speakers have the nickname "drum-skins" is because they are. :)

Follow Ups:
maggies are no more than what......2% or 3% efficient?
To go from electricity to sound and return you are going to get only a tiny return.
Mylar is Low Stretch. No edge suspension like a conventional woofer. I suspect a conventionaal
Acoustic Suspension speaker stores far more energy....an order of magnitude? = 10x?
Can you assign some number rather than the qualitative 'very little'?
So while I think 'zero storage' is off the table, I'd say 'not much' might be OK.
One other factor? How much Damping Factor do Maggies benefit from? I see many users with
low DF Tube gear. Electrically, I don't know if Maggies benefit from a high DF.....
As for viewing on a scope? What voltage range? How large an input TO the panel? I'd love to
attend and WATCH this tested. Cool idea.
Too much is never enough
