You're running JBL 2226J's on bottom with Altec 811's as upper mids, right? That's an excellent combination. Excellent! And then sometimes you swap out to the Martinelli's, right?

Seems like with the Altecs, crossover around 1kHz is perfect. Having the 800Hz crossover point with those is just fine. Maybe a little low with the Martinelli's, but his horns give a little more even dispersion. I like them better especially in cornerhorns. But everything you have is such good stuff, it's like comparing the best with the other best.
