What would it take to integrate a pair of SubMersives with 215RT fronts?
Equipment, programs needed....
A minidsp would be all you would need but I prefer the dsp of the inukes for the speakers so if it were me (and this is what I did) I'd get an inuke to power the 215's and a minidsp for the subs.
Well, then you also need a mic to measure the response and a laptop to have the mini and inukedsp hooked into. It makes it easy to watch in real time the changes you make to the dsp and how they affect the frequency response. 12 db slope crossovers and high pass filters work very well in my room.
