have you seen those wylde speakers ?

celestion makes em , they're kinda hifi in a way , they can be used for jazz but that obviously ain't what wylde does . the thing is when they break up they break up hard and you got enough amp to muscle them around quite a bit, yesssssssss quite a bit.

I doubt that's what you're after though but it's a thought .

what woofers are in your jbl speakers ? you know people have been known to run guitar amps thru 123a speakers as found in the century , don't know how it sounded but they held up. how attached are you to the jbl speaks you have ? cause I can think of an experiment..
