Hi Raimonds, I wholeheartedly agree it is ideal to correct each individual band/way.
But I don't think it's very tricky to use FIRs to create a multi way system ...in fact I think it's the easiest most straightforward way there is to set up a multi way system.....and makes all other ways look very tricky !!!
As to voting on your proposed unit....
May I ask how can you hold latency to 12ms with so many taps? I get 8192 taps, even at 96kHz has about 42ms. (centered impulse).
I guess you could jack the processing rate up further, but there goes frequency resolution, right?
Personally, I'd love to see an affordable, road worthy box, with 8 channels minimum, and the kinds of tap counts you're describing.
I've been using 8 channels of miniDSP .....4 @ 6144 taps , and 4 @ 2048......all at 48kHz.
For playback, it's totally awesome, but of course it's a pure non-starter for live.
So back to is such a unit necessary?
Well, IMO if latency is somehow brought down to 12ms......absolutely !!!!!
But if latency can't be kept down to make the box suitable for live,... I kinda doubt it
...And not even for playback...because even the relatively low $900 odd dollars I spent on miniDSP boxes begins to look expensive, when I learned about PC convolution.....
