The problem, and I think Mojo is having this as well, is I can't dial in the subs below as your saying. To get the 600 5dB's below, say 70hz the gain on the receiver AND 600 have to be at MIN. This causes a problem for the 350's as you have to crank them to the MAX which I'm having difficult to achieve.

On the flipside, If I use a higher target SPL, say 80dB, then I have to crank my other speakers so high on the receiver levels, like +12 or more which can't bedone.

I don't know if any of this makes sense or not. I think the problem may have to do with the 600 sucking all the power from the Denon, not sure.

I may stay home today, and work on this, not sure....
