Wow! Now that's resonant!

At last, a speaker system to give us that true concert hall sound. :-)

He's right they do vibrate but if they do it audibly they are crap speakers,
unless as is the case in some rather odd speaker designs, the vibration is
undamped purposely so as to contribute to the sound.

I doubt very much if there is a speaker that is of any decent quality and
normal design, that has a cabinet that emanates sound loud enough to come
close to the sound from the drivers.
