Does anyone anyone have any advice on how I should approach this using the Denon and Audessey? Any other tips/tricks you may have using the Def Techs with the Denon would be most appreciated. Thanks!
Congratulations. Nice combo.
Consider the possibility that with good room equalization you might no longer need the separate sub in addition to the DP speakers.
So, try both solutions. What you are currently doing now (split one sub out between the DP woofers) and the other sub out to the separate sub. But also try skipping the sub and just use the two ports to connect to each of the DP woofers without requiring a splitter. The latter after room normalization may sound better (especially if the room acoustics for the two DP woofers vary too much and present a challenge to the room equalization when a single port is split between two). Let your ears decide which one your prefer.
With bipolar speakers that are very position sensitive and the separate sub, you are juggling too many variables to arrive at an optimal solution.
Sometimes simpler is better. If you find the bass with just the DP series alone insufficient, then skip feeding the sub out into them, let its internal crossover treat it like a large speaker and let Audyssey balance between your separate sub and the DP series as main speakers (small/large as it sees fit).
As to the use of Audyssey with DP series speakers, it has the same caveats as using it with any bipolar distribution speaker systems. If you place those speakers sub-optimally for spectrum response and depend on Audyssey to make it better, it might be like putting lipstick on a pig. Moreover, the crossover decisions in those two can sometimes negatively impact each other.
So, typically if listening to music is also important than just thunderous movie sounds and dialog, this takes a very careful iterative process where you first place the speakers and try them on without room equalization to get the best possible sound (with ears as people did for decades!) and then doing the room equalization. Mark the position of the speakers at this point and repeat the room equalization at several different position of the speakers moving them towards or away from the back wall (as logistics permit) in 1-2 inch increments (moving sideways isn't that critical unless one of the speakers is very close to the side wall).
Listen for a while between each of the positions and pick one that sounds best to you for different types of content.
