"benefit" that I have).
So I'm considering a more mainstream processor with two DDRC 88A units. The Yamaha CX-A5100 looks like a good candidate. If new, the combo is right at $4,800, or $4,000 if I went with a refurbished processor from A4L.
I want to run four subs.
I also want active crossover for the center channel which is one of Wayne Parham's 4pi two way speakers with the 7pi mid horn. Due to available channel count on the DDR8 units, I think I'd run the 4pi full range with a notch filter where the 7pi mid horn sits. The 7pi horn is run full range in the L+R speakers but may need to be band limited and phase aligned to work well with the 4pi. Or I could drop back to three sub channels and do three way XO on the center. I have an extra Rotel amp channel available for the third driver. The center channel configuration is all speculation at this point
I read through the excellent tutorial by #kbarnes701
I sketched up this configuration for the hardware side. Does this look like I am on the right track? The Yamaha processor has independent sub outs, so I show them connected separately to the DDRC, but don't know if there's any advantage to doing it that way.
Here's a sketch of the configuration that I'm thinking about. Does this look like I'm on the right track?
I did pretty much exactly what you are contemplating except I used the Marantz 8805. I was running a 7.2.6 system so you could probably get away with the 7705 running a 7.4.4 and save a few bucks. I was extremely pleased with the results of being able to take advantage of Dirac while enjoying the HDMI stability and feature rich Marantz.
Hope this helps,
