    Opened up my Bogner OS212 today and found my speaker wire harness from the jack was pinched and crushed between the back of the cabinet and the support beam.

    Bogner DID NOT make it like that - that was my idiot old ass swapping speakers in a hurry one night and I must have missed it when I closed up the box.

    The 14 gauge wire was crushed flat over that 2 inch section. I'm replacing the harness, but I did play 4 gigs at pretty high volume like that. That's gotta add some kind of serious impedance to the signal, right?

    Is there a chance of amp damage?

    no

    if the wire is not broke, impedance does not change

    you mean there are not less of those electron thingies flowing affecting my tone?



    :rolleyes:

    Zero harm. Find something else to fret over!

    Just apply some KY gel on both ends of the crushed wire.
    Proper lubrication will work wonders to let those fat electrons slide in-out that narrow slit freely and with minimum resistance.

    A severely crushed wire definitely can be compromised. You might have broken any number of strands internally. Crushed wires are one of the most common reasons I see my companies product come back from consumers. I'd replace it, just because it's easy, cheap and the ramifications of the (admitadly unlikely chance of the) wire breaking are major.

    Did you notice an attenuation of dynamic range when the wire was in that condition? I've heard that can happen with compression...

    I dont think it would hurt the amp at all. The fact that it got crushed is a good reason to replace it though because no doubt some strands of wire were at least stressed. Bogner used some seriously thick stuff so it would take a lot to actually break it. It's reasons like this that they over engineer that stuff though!

    Thanks for all the replies - it wasn't the original 10 gauge cable that came from the factory - it was a 14 gauge harness that I installed when I installed the speakers. I've actually re-soldered the original Bogner harness back in today now that I've finally settled on the speakers I want in that box. The section of wire that was crushed was flat as a pancake and probably had some damaged strands.

    Oh ya thats right you did mention the 14ga harness. It's the 10ga stuff they put in there thats really heavy duty. You made the right call fixing it even if it still passed signal ok.

    Wow, 10 gauge wire for speaker wire in a guitar cab? Seems awfully silly given that 10 gauge is capable of conducting 30 amps of current. The engineers at Bogner have left me scratching my head more than once.

    I know, I know, 10 gauge sounds better than 14 gauge. Carry on.
