Sure, anything is possible. But the iLive version of the crossover section was less than ideal in patching and management. I would rather see implementation of things this console lacks on the console front. A modern RTA for example… interesting EQ modelling that could be inserted in via the FXs if need be. A latching Width button on the C series EQ area, A clock that doesn’t lose time.
No speaker manufacturer has done that because…Why would they? If you need FIR filters for your boxes you would buy what ever they spec. System perfomance issues usually can’t be solved on the console.
I purchased Dlives for one reason. They are fantastic consoles that punch above their weight.
