I just bought a set of SDA-2's and one speaker has tweeter and the dimensional speaker that is not working. I tested the speaker and they test good. They are both driven by the same crossover. any help would be appreciated.

    Are you using the interconnect cable between the two speakers? Half the speaker doesn't work without it.

    Double check the crossover to make sure all of the solder joints are O.K. I had a 1C factory crossover with a solder joint on a resistor that was never soldered and that caused one of the tweeters not to work. I just soldered the joint and it worked fine until I rebuilt my crossovers.

    SDA 2 3 woofers and 2 tweeter model will not have dimensional woofer or tweeter working without interconnect cable connection. Most folks disconnect the dimensional tweeters as it can add some freakie sounds that can be distracting.

    WHICH "SDA-2"? There's three official versions, plus some oddballs.
    SDA-2, SDA-2A, SDA-2B. Please confirm which you have. I'm guessing the original, three midwoofers, two tweeters, and the "outside" "SDA" midwoofer and tweeter don't work if the SDA cable is missing or has wiring problems.

    Better (more specific) to refer to "speaker" as the entire assembly with cabinet, crossover, and wiring, while the individual noise-making units are called "Drivers", "Mid-Woofers" or "Tweeters".

    Same crossover, different circuits within the crossover. Plus the added wiring of the SDA cable, and the socket/wiring for the SDA cable on the speaker cabinet. There's a dozen places where the problem could be. In fact, the problem COULD be in the OTHER speaker cabinet.

    Create a new thread. This has nothing to do with what your problem could be.
    It's apples to oranges
