^^ Thanks for the link, Keith - at least I'll compare and see what learnings I can squeeze out of this.
As to my quasi-jest that you're now ducking from: it actually has some merit for a system like mine! Maybe if you're drinking or suffering but advanced AVS tweaker sickness, or have too much spare time on your hands while waiting for data on a project, but I've got some reasoning behind this. Read at your own peril....
Think of it if you're me: you have DefTech Mythos ST fronts with a powered 'woofer' section, and a CS-8080 center that also has a powered top-firing 'woofer', and even with Small and 80/100 Hz crossover, there's still the areas that Audyssey isn't equalizing below the -3db point. And crossover isn't a brick wall, as we know, but a slope. That's where the subtle tweaks of PEQ might come in handy for them. On top of that, if you could address the little areas that the Pro Curve Editor, as a kind of/sort of crude PEQ, may not address due to the limited +/- 3 db adjustment range and relatively broad octave bandwidth, you can better optimize the system.
However, I would want these three speakers EQ'd as 'full-range speakers', to avoid the weirdness of pretending that I've got third, fourth, and fifth subs that are placed differently, but not nearly as capable, as my standalone ULS-15 Dual Drive. Almost like virtual 'mid-bass' modules, placed concurrent with mid-range/tweeter bookshelves, in a way.
But...the Behringer 1124 is designed for only two inputs/outputs, and the FBQ1000 and FBQ2496 are similar, plus you'd have three ugly grey boxes to handle all the channels (two subs, two fronts, a center)! That's where MiniDSP comes in, specifically their 10 in/10 out box (which actually is eight analog in/out) and 8x8 plug-in that supports REW EQ filter transfers. Unfortunately, while they can equallize the channels, they don't have speaker-level outputs, just level output AFAIK. Which means pre-out from my Audyssey calibrated AVR to the MiniDSP, and then out to an amp, because I can't really do a 'feedback' loop with my AVR. That's leaving aside the follies of what voltage to use for each input, which may or may not require adjusting individual channel jumpers
If I were truly interested in R&D and had unlimited time, I'd look into this route and compare to what I get from my more conventional hookup, do listening tests for the 4311 as the amp vs. the SC-27, etc. Or dig up a Pioneer mic, run MCACC with the MiniDSP (call it a separate balanced 2 x 4 and Advanced plug-in for simplicity's sake), and do full-blown A/B comparison between Audyssey and an MCACC system with bass EQ.
The other choice would be to spring for a real Class AB amp. I could even get strange and get a second 4311, and effectively have iterative EQ (Audyssey XT32->MiniDSP->second system with XT32), which would either be uniquely valuable or introduce other problems (or just be plain redundant, aside from having a common sonic signature from the same amps). Pity I got rid of my old Denon 5803....
Good thing I thought twice about this....Edited by sdrucker - 3/20/13 at 12:00pm
