Did I wire my 810 Correctly?

    I recently noticed the top left driver in my traynor tc810 was blown, so set out to replace it with an OEM driver. Here's a picture of the replaced speaker in place

    Now I'm wondering if I wired it up correctly, here's a pic of the wiring from the adjacent speaker, and the rest of the cab. The Colours in the diagram are the same as the colour of wire in the cab, with red going to positive and black going to negative.

    Someone with some knowledge please weigh in, it's driving me crazy!

    Do 'the battery test'

    If the cone moves in phase with the others, you at least know the plus and minus are compatible.

    For a R&R, assuming the new speaker has identical impedance as the one it replaced, the rest of the wiring can be assumed to be correct... It would be nice if there were universally accepted standards for + and -, but it's still best to test...

    I'm assuming red is positive as the red wire is coming from the positive terminal on the adjacent speaker, which was wired from the factory.

    What you cannot assume is that every speaker has the same meaning of positive.
    Does positive mean the cone moves in, or out?
    Best to verify - it's quick.

    plug a cable into the cabinet.
    one with a 1/4" phone plug exposed.
    an instrument cable is fine - there is not much power involved.

    While watching the cones, touch the terminals of a 9V battery to the tip and sleeve of the phone plug. (one terminal to tip, the other to sleeve.)

    If all the cones move in the same direction, ta da - done.
    if any move 'in' while the rest move 'out' - they are wired backwards from the rest.

    You have only the one that's really in question...

    They all move in the same direction. Awesome! Thanks so much. 😃
