Hello,

I have to recone/repair an Eclipse 12" sub with a mutilated coil, and an Alpine Type S 10" DVC with a blown tinsel lead.

Both subs have a single piece cone... how to I keep the coil aligned, especially when the spider was cut unevenly (both)? I'll try to epoxy the rest of the spider before putting the whole cone/coil/suspension assembly together before I finally put it back on the basket, but, how do I properly align a single piece cone sub?

--------------------------------------------------------​

And I have another problem. I have a JL w0 10" (the newest model), and got it for cheap ($20). I brought it home, and it made a slight buzzing noise on low volume. When I turned it up, it went away (or it was nicely masked). Sounded like a wire or two was loose on the coil. Still perfectly usable and very nice sounding. A little epoxy will fix right up, right?

Wrong. I opened up the driver to find nothing wrong with the coil. I "fixed" it with epoxy, and let it set overnight. I plugged it back in.

PLPRLPRLRPLRPLRPLPRPLPLR!!!!!

It sounds close to a square wave, even though the coil and everything is aligned. No coil scratch either, which is strange.

I killed a perfectly good 10" subwoofer, before I ever put it in a box! What do I do with it? I have a half working subwoofer that I'll never use. It has a nice coil, moves a lot, and still has linear movement. There's just a loud mysterious noise coming from the inside, and I'll probably do more damage than good if I try to fix it again. And I don't have it in me to put a sub in the dump when it has a working coil.

--------------------------------------------------------​

So, how do I re-cone an Eclipse? They don't have re-cones for Eclipse's lower end, not to mention a guy at a stereo shop said that Eclipse is out of business.

I was thinking about carefully making a voice coil former out of aluminum from a soda can and then using epoxy to hold it together and to keep the coil on there. The epoxy I have can handle 300 °F, is that good enough?

And I was thinking about playing a low volume tone to help align the coil while the epoxy dries on the Alpine.

Thanks in advance!

Thank you!

However, the Alpine's coil won't come off of the cone, and there is no dust cap to remove because it's a single piece cone. Would it be a bad idea to cut through the cone itself?

As for the JL w0, it has messy epoxy all over the surrounds... I'd have to mutilate it further if I wanted to do anything with it because I already put it back together (poorly). Is there anything I could use to remove the epoxy?

For the JL, there's just too many jagged cuts through the surround. There's no way I could piece it together and retain the T/S parameters. The epoxy dramatically stiffened the suspension, both the spider and the surround. Unless I find get ahold of raw speaker parts, it's gone. Luckily, it's the new 2011 model, so I got a new one for $70 :).

As for the Alpine, I was successful in gettin the former off the cone. There was a plastic piece cconnecting the former to the cone, and I can't cut through that. But the backside of the Alpine's cone was paper, so I just had to use a letter opener, and some finger-grease (a pun on elbow grease).

Once I get some more epoxy, I'll begin the recone the Alpine.

Thanks for the input, I'm off to get the epoxy!
