    Does anyone know where I could drop in a cab to be repaired? It stopped working and there doesn't seem to be any loose or broken connections.

    What kind of speaker is in it? I don't think there are many people around these parts capable of repairing a speaker, and it might be a bit of waste of money to pay someone just to buy you a replacement.

    There's really nothing in repairign a cab to be honest mate...
    If the speakers are blown, then they need replacing, it's a simple job. Wiring a cab is pretty basic as there's only two wires in a cab! :)

    I don't know what kind of reputation they have, but I came across Sound Factory:
    http://www.myspace.com/instrumentrepair

    Its a job that basically a lot of guitar-tech guys could do (just some simple checking of the wiring, and wiring in a new speaker if necessary), so I would say even some of the shops in town would have a look at it for you.

    It's a 2 x 10 with Jensen P10r's. The speakers are rated 25 watts and all I had going in was a little 7 watt amp. Didn't even have it loud. It was working fine, I disconnected it to move it, plugged it back in and nothing. How do you blow a pair of speakers?

    You can either overheat the voice-coil (by putting too much current through it), which can melt its insulation and cause a short, or the cone can mechanically break (tear, pull away from the glue etc) from being vibrated too violently.

    I wouldn't say you've 'blown' a speaker. It could be just a wiring problem, or a defective speaker, or if it has a switch on the jack dish, there could be a bad connection there. Like Kranog said, there's not really too much to go wrong, a good tech will troubleshoot it in a few minutes. Worst case scenario, you just need a new speaker(s).

    Some guys would do it themselves, but if you're not handy with that sort of thing, no harm in leaving it into a tech.

    Did you try it with a different speaker cable? It could be the cable that's fooked?

    Nah, the cable is fine.


  • Registered Users, Registered Users 2 Posts: 2,117 ✭✭✭Eoin Madsen


    You should move it back just to see if the problem is where it is. :pac:

    It would be really really difficult to damage a speaker just by moving the cab. Can you see if they're wired in series or in parallel? If they're in parallel the diagnosis is almost certainly wiring.

    I'd wire something else (a solidstate amp at low volume) directly to each speaker to test if they work that way.


  • Registered Users, Registered Users 2 Posts: 1,433 ✭✭✭Quattroste


    Series or parallel? There is 1 input jack and 2 sets of wires, one going to each speaker so I guess they are parallel???

    I am going to get it tested by a lecky mate for continuity from the jack plate to the speakers. Pain in the hole this!


  • Registered Users, Registered Users 2 Posts: 2,117 ✭✭✭Eoin Madsen


    That would be parallel alright. The failure of one speaker wouldn't prevent the operation of the other. And because they're both wired from the jack rather than cross ways, it means that the problem has to be at the jack end for the same reason.

    If you have a multimeter, I'd check the jack for a short.
