Sda compact crossover problem

bulldogfish

Iam new at working on speakers.One mid and tweeter are not working on each. I have tested the woofer and tweeter on each speaker and they work.I believe the top crossover is the problem on each speaker.Do I need to replace all caps and the resister? Any advice would be great.This model has 2 mids and 2 tweeter and the passive woofer.

Welcome to the club bdf.

Before you go any further you should run the troubleshooting tests which you can find here (post #9 at the bottom): http://www.polkaudio.com/forums/showthread.php?55888-POLK-AUDIO-Speaker-Wiring-Schematics-amp-More-Stereo-Dimensional-Array(SDA)

Do you have the interconnect cable that runs between the left and right speaker?

without the interconnect hooked on that pair of CRS i do believe that it would act just like the OP described.

Yes It appears the speaker need to be wired in reverse phase. How do I do that?

Did the red and black nuts on the binding posts get switched? On both speakers the red nut is to the left as you face the back of the cabinet.
