Thanks for the respose. Although I generally don't play very loud and my speakers never get used for backyard parties, some of my classical favorits have quite a lot of dynamic range. These peaks are usually short in duration but they can suck a lot of power. The nice thing about the 4540 is that it is cheap enough to experiment with.

I'm sure that the Peavy horn goes low enough to cover a 16K crossover. I had read that the JBL has a little better dipersion on the high end. Weather that's worth the large differnce in price is another thing.
