shepjk01 Posted April 17, 2013 Share Posted April 17, 2013 I'm replacing the crities woofers in my dbb's with jbl 2226j's 16ohm version and need a little help modifying my current crossovers woofer section. My mid is a jbl 2485j on a elliptrac and a jbl 2404h for the tweeter. The current crossover is the standard klipsch 400 and 6000hz I have included a schematic of my current crossover configuration Quote Link to comment Share on other sites More sharing options...
