If the process of dialing in multiple subs can be automated, it will be impressive.
I am not aware of Trinnov having any secret sauce in the bass regions. Many of the Trinnov owners use a MiniDSP to manually sum the sub channels just like the rest of us. It would be nice to find two rooms setup identical at a trade show with one running Trinnov and the other Dirac Live. I might be a convert, but I would have to hear it first.
Not exactly secret sauce, but I can give you a few reasons to go with Trinnov for the bass regions:
1) Unlimited PEQ filters per channel (last time I checked, the MiniDSP software supported six at most)
2) More control over speaker delays (MiniDSP is up to 30 ms, Trinnov goes up to 50 ms on the setup you'd use to integrate up to four subs into a single output channel)
3) Multipoint position weighting, if you want to use some measurements vs. all and adjust how you want to weight for emphasizing MLP vs. a more spread out approach
4) You can decide where you want IIR filters to stop, and for mains, tinker with not only the transition frequency between IIR and FIR, but the octave level of the acoustic correction
5) If you really want to get esoteric with a 3D audio setup, you can have triple bass management, with the full-range mixed content for, say, front heights go to subs up to 80 Hz, cross to the speakers underneath (L/R in this case) to 120 or 140 Hz, and then be played by the height speakers.
To be fair, this takes some hands-on training to use, or you do have to hire a pro. But Trinnov has gotten extremely good at supporting enthusiasts these days, even working with some at odd hours of the night US time. They're also doing free seminars online that end users can attend more recently.
Not saying this is worth the price premium, or doesn't require tradeoffs if you're going to use an Altitude 16 compared to a 32 (namely, whether you use that MiniDSP or equivalent for managing the multiple subs or not due to the channel count limitation), but if you're a hands-on measuring type, I couldn't think of a better tool for implementing MSO results and optimizing the sweet spot for bass if you don't mind some manual input.
