Hmmm, well, I'm in favor of trying funky stuff to see if it works. My first reaction here was
a)don't do it
b)it's crazy
c)you need more power
d)wrong application of the 4648A
e)too high of a x-over point
f)JBL would laugh
g)then again, maybe not
h)WHY do this?So anyway, if I was faced with all this it probably pretty well guarantees that I would try it..........just for the hell of it..and if it worked and sounded good, it would be all the more amusing!
