Hi all good people.
Based on the forum I got an Ashley XR 1001 active crossover for a pair of JBL 4343's. The loudspeakers does not have the stock woofers, but a pair of 2235h, hence I'm not certain what the best crossover frequency would be.
I will be using subjective listening as well as UMIK-1 and REW to tweak my way with this, but a starting point would be very nice.
