Crossover help

#1 Post by Djones87136 »

Hello!

First time builder here (DR200 build) and I'm insanely confused by the crossover board. Maybe this is extremely simple and obvious but not to me. So I bought the pre built boards from speaker hardware and I have the array built and wired but I'm confused about how I'm supposed to wire the array and driver to this board. Can anyone give a newbie some insight into what I'm missing?

The markings on the board:
Common is negative. All negative leads go here. Amp, tweeter, and woofer.
T+ is tweeter positive
M+ is Midrange positive
+IN is the positive from the amplifier

And if you're using a eminence compression driver for HF, then the black marked connector is +, not the red...

One can't assume correct tweeter polarity. The plans take that into account.
