Is there an easy way to repair a blown sub? Or replace it? I've had this set of speakers for about 7 years now and I absolutely love them. I'd hate to have to get rid of them because of a blown sub.

Do you know exactly what wrong with it? Did you pull it apart?

Does it just have a driver is it or powered amp as well?

Haven't pulled it apart yet, but it sounds pretty similar to the sub in my car when that blew. It's powered and as far as I know does not have a driver

First driver = speaker
Second its going to be a blown surround as it sill makes sound so the voice coil is at least still functional. Best bet would be a replacement driver. If there is a suitable replacement online if not then there's not a lot that can be done.

There's a decent chance the driver's not an off-the-shelf part, considering it's JBL we're talking about.

Unless you've restored this kind of stuff before and can cludge something here, considering the performance level and what we're dealing with, you probably just have to let it go, sorry.

I figured as much. Caved and got a pair of Klipsch speakers. REALLY nice. I suppose it was just time for an upgrade. Thanks for the help guys

They are well known for having the foam on the sub woofer crumble into dust. Very poor quality on JBL's part. They sound great and are nice but die due to sub failure. I have 4 of them with the exact same problem. Work fine but sub foam deterioration. Working on re-foaming them.

If you're handy, you can do a really ghetto fix by using some sort of cloth or neoprene and rubber cement to keep it on the cone. This will keep it from sounding flappy and blown, but won't last forever. I've never done this with a sub, but I've done it with quite a few paper cone midbass woofers with decent results.

I miss $250 GPUs that could still play everything.
