Which Rane Crossover are you talking about? Probably you are talking about the analog models since digital one is $800. I have a 3way with sound delay circuit.As to the equalizer, at the risk of appearing knowledgeable, don't get one that isn't at least constant Q. Also its worthwhile getting the 1/3 octave model, but I have a 2/3 octave which works very well. Mine is DOD Constant Q.
What does buying a big lens have to do with an equalizer and a crossover?
