boy, as a music lover (all kinds) and professional musician, i almost have to wince at the thought of someone auditioning speakers based primarily on volume level, and laughing at the notion of seeing whether one can "blow them up". it seems almost juvenile, and at the risk of offending someone with my remarks, may i suggest that music should be about more than seeing if we can blow up our toys in the sandbox.
it reminds me of a concert i did recently with a rather well-known jazz drummer. during the sound check, he hit his bass drum,this was in a university concert hall, and it sounded HUGE!! this drummer argued a bit with the young sound engineer, who was only accustomed to loud thumping kick-drums, until he got fed up and told the kid to turn off all the mikes on the drums. he then played a little around his kit, smiled, and said, "that's the way it's supposed to sound". there is a great deal to be said for subtlety---in ALL music.
to judge a music transducer based solely on whether it can break glass, eardrums, or burn rubber, "cleanly" or uncleanly, is really missing the point of it all. IMHO!
