Blown Subwoofer?

Hello acurazine, im looking for an expert in this area, because im not too knowledgible at audio. I have a jl audio 500.1 amp that was connected to a 10w7 subwoofer. One day the sub stopped playing so i tryed to connect a sony xplode sub to the amp, and that sub worked for awhile. I knew i was going to blow the xplode from all that power, and that day has come. When i try to push down on the xplode with my hand it wont move at all, but i can push in the w7. When i push in the w7 though there is a slight skeaking noise. I find it hard to believe that I blew the W7 from 500 watts. Anyone have any insight?

I think under the right conditions, any amp can blow any sub. Also, I'm not too sure if you're supposed to press on the sub like that. lol.

Take the W7 to an authorized JL dealer and have them check it out. It is worth some time and effort.

They will bend you over and rape you with no lube for a recone. You can't get a recone kit directly from JL. You would have to send it in and let them recone it, but it will set you back atleast $300.

Team PSI could've did it if it were the 12" version.

Here's a recone they did
So I got in a 12W7 the other day. The surround was done. It has been rubbing against something enough to wear all the way through the foam surround.

So LETS CUT IT APART......


The first hurdle to jump, the basket. I surely dont have any weird, edgeless, extra big cones here... I guess I'll need to use a new basket. to do this, I have to re-drill and tap new screw holes on the top plate. :angry5:


That's a PITA of a process there. It's not fast, or easy, or cheap to do.

Now, on to the soft parts....


The old coil was kinda, meh. I decided to make some new nice flatwind coil for it. Dual 1.4 ohm

The owner requested that I use a 12 spoke basket, here it is with the new basket, coil, suspension, and leadwire...



Is that PINK thread......


Direct connect leads


Looks at that coil!


Now she's all done, new cone and all.

Wow that looks like some hard work to recone. I might think about sending the 10 in to JL one day if im feeling rich haha. She was a beast of a sub while she lasted...
