[QUOTE="Steve Garris, post: 122841, member: 1498"] Re: Do you take your crossover for granted? [Powered Speakers] Interesting thread - There are things being discussed here that I don't fully understand, but I'm trying to learn! I'm using JBL PRX-615's over 618xlf's. Sometimes I just use the internal crossovers, and run the 615's full range (main setting). This usually sounds good, very well balanced. When I'm mixing my Beatles band it makes for a quick and simple set-up that just works. When I was mixing my loud hair-metal band, I noticed that vocals would still light up the limiter light on the xlf's, even with a HP filter set on the vocal channels at 150hz or so. Later, I re-wired everything to do an aux-fed type mix (Left output to subs, Right output to tops). I think this works and sounds better, but I have some more evaluating to do. Lastly, we recently did a gig at a club that had some KW-118's. I hooked them up with the aux-fed mentioned above, and was blown away at how good the whole system sounded. Kind of makes me wish I had bought the QSC's! One issue that I have, maybe there's a solution or perhaps my method is causing it. I hear a lot of comb filtering or null zones in the bass response between 60 and 100 hz. I typically just think it's the room's boundaries, but playing with the polarity seems to move these hot spots and weak spots around. I usually test the polarity on the subs for most output (as heard from behind the sub). Is this all wrong? [/QUOTE]
