    Before I explain what I did to my 410TX, I just want to say that I will not be held responsible for any damage you do to your cabinet, speakers, or amp (highly unlikely). Peform this at your own risk.

    Technically, this isn't a complete crossover bypass. Essentially what we are doing is removing the .5uH inductor from the loop. I don't know exactly what this does because I haven't bothered to figure it out, but to my ears it sounds like the cabinet is broadcasting a lot more midrange.

    When you remove the back panel (where the jack is located) you'll see a few things:
    1) Yellow & Blue wires connected to the greenish-yellow PCB board. These go to the speakers (it should be labled "Woofer")
    2) Yellow & Black wires connected to an inductor screwed to the inside of the cabinet. This should be labeled as well.
    3) Red & Black wires connected to the tweeter.
    4) Red-Blue-Black wires connected to the tweeter volume dial.

    The easiest way to do this is to cut the yellow and black wires going to the inductor and then connect them together, thus removing the inductor from the loop, but still allowing signal to pass through. Make sure you connect them together securely. Solder is best. Also make sure you wrap the bare wire with electrical tape to prevent a short.

    I also disconnected the tweeter on my cab because I hate the sound of it. All you have to do is take out the black and red twisted wire. Disconnect it from the tweeter and the PCB.

    If you wanted to completely bypass the crossover, the easiest way would be to get a new 1/4" jack, remove the PCB board completely and connect the yellow and blue wires directly to the new jack. You wouldn't be able to use the tweeter though.

    Hope this helped some of you.

    Zombie thread reply...

    Just seeing what the outcome was from anyone who has done this with the peavey 410tx. I hate the tweeter, cracks, pops, sucks.

    My TVX (same basic cab) was given to me with a pre-blown tweeter ;) . The mod definitely makes a huge difference in sound :) .

    I've only shorted out the inductor so far. I'll eventually pull the plate again and do a better job at removing the crossover components. I'm presently using it with a 30w tube amp so might rewire the tweeter l-pad as a master attenuator :cool: , probably with a bypass so I don't smoke it with a bigger amp. I'm using an external speaker soak at the moment...

    The tweeter in those cabs is pure hiss, not sure how you even use them to begin with. :) I performed Plan B on mine and just physically removed the entire crossover from the jack plate and direct wired the speaker to a new 1/4" jack. Huge improvement all around.

    thank you for that reply, think that is what i will do. seems like the easiest and that way the crossover is still intact need be to sell if I had to. Thanks
