    I have a Roland CK-60 combo, a keyboard combo with a 12" and a horn. The horn has to go, it makes bad sounds.

    I don't know if there's a crossover or not. I searched, and read that if there's a crossover it should also be disconnected.

    The horn is wired in parallel with the 12" speaker. The two wires from the amp (a connector plug) go directly to the 12", and the horn is wired in parallel to the 12".

    Is it ok to simply disconnect the leads to the horn?

    There's a cap or resistor across the horn (in case that's crossover part).

    It's a piezo tweeter. You can simply unhook the tweeter from the 12 so your signal simply goes input jack---->12 with no resistor in the way.

    Leave the tweeter mounted in the cab, just to plug that hole, so you don't throw off the box tuning for the woofer.

    All of the stuff I got for free wore out!
    I think what you call the resistor on the horn is a capacitor, and I think that that is the only crossover that this amp has. Once you disconnect, you should be good to go.

    Thanks. I'll leave it in there so I don't lose it.

    There's a board that goes across the cab between the 12" and the horn, sort of separating them.

    The thing in question on the horn looks like a block resister (I think).
