Well it didn't start like that right away.
Now I need 10 channels but I started with 2 way so 1 shd, then 3 way with passive crossover, then +2 active subs with an added shd studio in front for a while.
Got good results with the passive filters since they're adjustable (focal crossblock).
But I rebuilt the system when I moved, and different drivers asked for more correction, so I added another shd.
I was about to try ddrc88+okto, but it was in my case easier to just add one than to replace everything.
So the studio was driving 1 shd dedicated per side for a year.
It was clean this way, and the presets were almost identical so easier to manage in the plugin (but I save you all the user errors with two computers, all these presets to manage and the volume check for rew sweeps
).
Barely using Dirac now but I still need the studio for the subs, a 2x10 would be great and simpler, but I won't wait for it.
