So the idea here is to first determine what crossover points/slopes work best. As in, let's say I use REW to arrive at (for example) 80/600/3500 at LR24 as a good solution. I then disable the crossovers, use APF that match (in this case Q=0.7 in place each of the low and high pass LR4 crossover), run Dirac, go back to the plug-in and remove the APF and re-enable the crossovers?
So you don’t want to use REW so much….
you want to do a run on Dirac with no crossovers and no APFs and use that to determine your desired crossovers…. Simply what has the best imaging cues and staging attributes and tonality.
then go back and run Dirac again with the APFs on and crossovers off , then turn off APFs and crossovers on when Dirac is over
The crossovers will sound completely different post dirac then they would with a REW tune….
dirac changes the timing in ways that will alter the crossovers so much that a REW tune won’t be anything like it…. Dirac does a far better job then what can be done in REW for one , but the timing changes simply invalidates any REW work.
It’s sorta like how after Dirac any peq in any modal areas can destroy the ambiance and make the tune sound flat, because the peq is at the wrong time.
