Denon X6800H 4-sub question
Hi, I am looking for some advice from the Denon-competent. I have a particular speaker setup in mind, and not sure if the X6800H could handle it (and if not, what would be able to do it).
I want to run a 4-sub setup, where 2 of the subs are actually the (active-amplified, powerful, capable) bass drivers of the FL and FR speakers (consider these drivers to be fully competent for subwoofer duties). The other two subs are normal, standalone subs. I am trying to wrap my head around the best way to do this with a modern .4 AV unit and their bass EQ abilities. NOTE that they will most likely XO at 120 Hz to the higher-frequency drivers of the FL and FR speakers, whereas the other 2 subs will XO at 80 Hz.
[Option 1] If I simply run the FL and FR as ‘full range’, and only utilise 2 of the four .4 outputs on the AVR, does that then limit what I can do with the ‘four’ subwoofers? Do I still get LFE to all 4 subs? Can the X6800H do LFE distribution? With this setup, I suppose that the sub-bass frequencies in the FL and FR program content will no longer be distributed to 4 subs, in which case, the benefits of having 4 subs will not apply to all the bass content in the FL and FR program content? That seems a bit less than ideal to me, don’t you agree?
[Option 2] Alternatively, I could utilise all four of the .4 outputs, by powering the FL and FR active bass drivers from two of the AVR’s subwoofer outputs, and designate their crossover point at 120 Hz. Do you see any big problems with this idea? Does it actually provide any benefits in terms of subwoofer benefits, or flexibility, or utilisation with Audy or Dirac? The only real negative that I thought of, is that I am stuck with the standard AVR crossover slopes at the (120 Hz) XO to subwoofer, whereas using them as a full-range speaker allows me to apply a digital XO and slope of my choice to the next drive unit.
Can the X6800H handle both of the above alternatives? Any limitations that would apply? If so, are there any other AVP/AVR units (excluding Storm/Trinnov-like budgets) that could do it better?
What if I try to implement a Multi Sub Optimiser setup? Is one of the above configurations better for this? Is the X6800H suitable?
thanks
