This is what I've been looking for. Arrived today and I took Hitman's advice. Muted the keyboard speakers. Next, by just hooking mono to the QSC, I went through each song (so far) and make proper eq adjustments.

But the killer dynamics of this speaker are absolutely terrific. For once, my arrangements sound like they should in a balanced mix, with beautiful separation of instruments.

The bass, mids and highs are all DISTINCT now and they really do BLOW AWAY my 800 speakers. I cannot believe how a quality and highly refined product can make such a HUGE difference! And I've been calling myself a professional

Thanks Hitman
