This foam gave nothing to do with sub, it was there to cancell echo from casing, if speaker, regardless which, is gone bad, there is no repair for it. it need to be replced.

in your case, if sponge is gone, most probably membrane deteriorate and go off the coil as well, you cannot fix that unfortunately.

if you find my advice helpful, please do not hesitate to give me your vote.

    I think I have the same problem:
    In DEC 1998 I bought a Gateway PC with a Digital Media Theater, P/N 7000787. In the meantime the speaker in the sub-woofer got damaged (because of age). Is it possible to disassemble the sub-woofer and replace the speaker?
    Where can I buy the same or a very similar speaker for this sub-woofer? Thanks, Andy Szekely

    I just want to say that the bzet1820's information isn't correct. You CAN repair the foam around the speaker if you order a refoaming kit on ebay or the web. Here is a kit online for $10 dollars that includes the new foam, glue, and brushes specifically for the size of this subwoofer:

  • unosturgis Dec 20, 2010

    If you want a new speaker, the one inside the sub is 6.5", 4ohms. You may have to dremel out the opening a bit if the speaker you order to replace it is slightly larder than the hole.

Subwoofer output distorted

Check to see if the speaker foam surrounds have disintegrated on your subwoofer. I bet it is. If so the speaker will sound like it is distorting or vibrating. Electrically it should be fine. My 2000 Avalon has this same problem with the 8" JBL subwoofer. It is a common problem and an easy fix. Go online to ebay or Amazon and purchase a speaker foam surround replacement kit (Ranges from $18.00 to $25). Youtube also has "How To" videos on how to repair this on your own. I just ordered my foam kit and awaiting the parts. Here is one for $23 but you can shop around for other deals.

Our speakers have a "rattle"

Without the foam they will definitely rattle as you mentioned.Probably 3/8" - 1/2" thick should do it as it should compress when you reattach the speaker.It really doesn't need to be specifically for speakers.At least I would just find something available cheap.Foam is foam really.If you have any questions or need more help,just comment here and I will get an autolink to your post and reply ASAP.Good luck,Greg

The foam is molded, you can not remold / repair
If it is a small tear you can repair with a bit of rubber cement. Eventuly it will fail and more will tear causing the sub to sound very bad

The 6.5 foam ring

This is a very common problem and I don't know why companies still use foam.

The ring is called the "surround" and the problem is known as "surround rot".

There are 3 fixes.

Replace the entire driver. (most expensive)

Recone the driver (tear out the old cone + surround + spider and glue in a new one using the old basket).

Refoam the surround. (replace just the foam surround).

I know of one location in my hometown (Ottawa Ontario, that does re-foaming and people that do this are few and far between).

If you can find someone to refoam it go that route, failing that do a recone. A recone will last just as long as a new driver.

Hope this helps!

Smells like rotten eggs

The smell of rotten eggs normally means you have some water that has been sitting arround awhile and has gone bad. You may have to unplug your machine and remove the front cover to take a look arround the inside of your machine to see if any water has leaked out and has puddled up. You may also have something caught in the drain pump's filter, which may have gone rotten from sitting around too long. This filter is easy to unscrew and gain access to once you have the front cover off. Make sure you have lots of towels or a wet vac handy when you unscrew the filter cover.

Change out the ac blower

unhook the battery find the blower motor unhook the power connection wire it will be a male female type connector most likely unhook it and remove the bolts securing the blower motor to the housing it should pull out with minor effort it will probably seem to have glue but it will be a gasket usually made of foam that sticks to it. If the foam is badly damaged find some simular foam at the hardware store reinstall reverse of removal.
