So, while my JBL 250 Ti passive crossovers are in for repair, I thought I might try an active setup - just as an experiment. I have a dbx 234Xs crossover and 4x200w amplification running fully balanced, with 2+2ch gain control, as a test setup. 31-band analog equalizer. Thinking I'll do one speaker first, and keep the second passive, as a model. Have a 12uF cap for the tweeter. I know DSP come to mind for many, but I want to keep it an the analog domain, hoping the dbx will do for the experiment. I have a UMIK-1 and REW, but sonic pleasure is the main goal . Anything else I should think about? Dagfinn
