Jason,

When I went to hear Klipshguy's system, his riser was quite high - not sure of the exact height, but I would guess it was similar to the one you're building. While sitting back there, I noticed the higher frequencies were attenuated. I'd consider tilting the mains back, or putting them on risers as well. Just my 2 cents.
