Guys where's the sticky on the 5805, I couldn't find it.
Audyssey actually pings each sub separately. I have it set at the moment to LFE/Main. The subs are at the front of the room on the inside of the mains. Interestingly it set the Main Sub at -6db and the LFE at -3db.
In the separate sub settings page I have it set to THX so it's LFE only, not LFE plus mains, however the Sub getting the Mains feed still works.
What the manual doesn't explain is if you choose the L/R or F/B options over LFE/Main option what happens to the LFE track?
Tempted to also try using a Y cable and just tell the system u have one dub to get pure LFE on both, but I'm sure the clever Denon folks have set these options for a reason?
