^Good point^IDK, there is the sharpening of the impulse response Dirac Live does which, AFAIK, no other 12v product except maybe the APL units can do.
Maybe you should just get a marketing job with those guys, you've almost convinced me to upgrade my 8x12.Its for 1 reason. Dirac does it better faster. I can spend 2 days in a car. Listening and tuning and Dirac can literally give me a tune 10x better in 20 minutes
It basically does FIR super accurate eq across the whole spectrum and does all pass filters and phase adjustment and time alignment in 20 minutes. Its stupid good.

Well the initial discussion was how it compared to the Helix and in that department in install knowledge needed. The Mini Dl, i believe, has a far lower ceiling.I would be very hesitant to say that the mini DSP with Dirac can give "anyone" an expert quality tune in 15 or 20 minutes. It isn't quite sophisticated enough to fix problems in the subwoofer and midbass overlap without some knowledge of fixing it yourself before you run Dirac. It also doesn't set your crossovers for you. Give it to someone with little tuning experience and the results would be unpredictable.
That being said, it will give pinpoint imaging and sound stage depth that is very difficult to get by even expert tuners if set up correctly. And it will do that without the ton of EQ work that woukd normally be required.
I would also disclose that in my own experience that the unit I installed was very buggy in the beginning. It gave me fits for a couple of weeks until I did a hard reset.
I like it well enough that I just recieved a second one for my other car.

I banged out a tune at finals on a friends helix in 45 minutes that placed 3rd in his class...IMO the Helix can absolutely sound as good, you just have to be prepared to spend a lot of time to get there.
In a perfect world it is the Dirac delta function... named after Paul Dirac.what is sharpening of the impulse response?
Basically... The FIR filter corrects both REW and phase.
I don't think that the gating would work... the reflections are just too close in time.
