    I was playin' through my fEarful 15/6/1 and started paying attention to different buzz that were happening. (There are a lot of things in my practice room that rattle.)

    Anyway, First culprit was the 1/4" jack. I plugged it and next up was the bi-amp speakon. (you can feel air coming from it as well)

    I searched around here a but and only found info on 1/4". I even found a post where a TBer said that speakons don't leak. :meh:

    I tried sticking in a speakon plug I happened to have lying around and that just shut off my 3015LF. :mad:

    Right now I have a piece of tape covering the culprit, but am hoping one of you guys will let me in on the right way to fix the problem.

    Thanks in advance!

    Seal the back of the speakon with hot melt glue or caulk.

    Thanks Bill,

    I am not looking forward to this though.
    The jack plate has a circuit board mounted to it on stand offs.
    I am hoping the speakon isn't connected directly to it. :rollno:
  4. What's wrong with the tape?
    Gives you the option of using the Speakon when needed and resealing when not in use.

    I figure I should do it right.
    If I seal it on the inside it should be ready to use whenever.

    I haven't seen those automatic-selecting biamp connectors, but make sure if you do a back-seal that you don't foul any mechanisms.

    If you bought the Peavey ECX crossover thing, I would get that sucker done under warranty and leave it alone :)

    If there are any holes unused, just puttiing small bits of wire in those holes has worked fine for me.

    I hadn't thought of that.
    Actually I'm not sure if I have a warranty.

    I haven't noticed any holes, but it feels like air is blowing right through the speakon jack.

    Dang I would hate to remove the crossover though. Mainly because I sealed everything in. (including the mid wires siliconed through the little hole in the mid box.)

    I'll probably pull off the jack plate this weekend and have a looksee. If it looks like I can fix it easily (I've got plenty of silicone leftover), I'll just fix it.

    If not, I'll contact Peavey.

    One thing for sure though.....

    If my drummer is feeling up to it, the fEarful is getting a workout with the band. (still hasn't happened yet! :()

    You figure correctly. Tape is a band-aid solution and not worthy of use on a FearFull!

    Look at the 2+ and 2- holes carefully -- are they wired with anything? I've run into this problem with my DIY cabs. The holes whistle like crazy if they're unloaded and you're using a lot of juice. You could just replace the Speakon connector with a sealed one too, by using the type with push-on terminals rather than open holes in the back. I've seen warnings lately on some vendor sites regarding this problem, FWIW.

    I don't necessarily think Peavey is on the hook for this one. They may well use a sealed cavity for that crossover in their cabs?

    best of luck,

    Well, I had a quick look inside today.
    I really didn't want to start a repair just yet since I have a rehearsal tomorrow and want to give the cab a workout.

    It turns out that the speakons are soldered directly to a circuit board.

    What I am thinking is to smear silicone around the base, (where they attach to the circuit board) along the body of the speakons and where they meet the jack plate.

    AFAIK silicone is not conductive. :confused:

    I would make a sealed box for it, but that opens another can of worms. Namely I would have to make a patch panel for the wires since I would have to install the jack plate from the outside of the box at that point. I really don't think I wanna go there. :meh:

    I would just leave the tape over it, That little bit of air is not going to hurt your sound in anyway, all you want to do is stop the buzz.

    This connector must be a "Generic Speakon". You get what you pay for with a Neutrik speakON... The chassis mount jacks are supposed to be airtight. BOB

    This one is only designed to be airtight when mated to a female counterpart, or when all the holes are plugged with wires or a sealant of your choice. And as I said, it makes substantial noise if installed bare into a woofer cab.

    I have no experience with the solder-on ones though, but if they meet the same Euro standards they may well work the same way.

    Huh, lookie there an NL4MP-ST or Straight. Charlie, I've never even seen one of those previously. All the ones I have are either solder or the various plugs.

    I printed out the 9 page section off last night, but just looked at it. All the NL series solder connectors list as a feature "Air TIght Design" optimized for speaker applications.

    Sorry to hear the screw ones do not. They also do not specify air tight as a feature.
