When I wired the 2420 on the longer L300 horn, and 2405 to the 2235, I have to run the
Amp Black to the
Speaker Red or the Yamaha reports them as out of phase with the system. Makes no difference to the Yamaha's automatic set-up routine how I wire the horn and tweet.
When I used the Behringer 61-band RTA to set the horn and tweeter phase, I seemed to get the smoothest curve in the room with the horn and tweet wired with the
Driver Red to the
Crossover Black and this is how I've been running them for years. I find that the horn and tweeter always seem to phase best together, but changes to the tweeter phase are very hard to hear regardless.
But recently when comparing speakers, to first recognize the deficiency, and after many hours of doing A/B/X comparisons with the wiring, (I can do that
), I came to the conclusion that even though, the Behringer
may have looked to be smoother across the band wired as it was, it
sounded better the other way with the major advantage being
intelligability and tonality of the vocals. I find this to be one of the hardest criteria for speakers to reproduce. So I changed the wiring for the better, and need to get into my center channel to do that one too.
BTW, I recently also found a way to "lift the veil" from the 2405 making it "sparkle" as it can and also adding intelligability. But that's for another post.
