I just reinstalled my left rear speaker after using this thread to order parts and DIY! The process is pretty straight forward. The stock system never sounded better as one of the woofer has been blown since I bought the car......

Schocki, thanks for the detailed info it was a great help. I would have been hesitant to attempt this with out your post!

I did not update my experiance with the re-foamed speakers.
Fitted them prior to SITM and my stock system is amazing again.
Peter Gabrial never sounded so good.
I am really glad I stuck with the stock system as it is awesome.
Thanks Shocki.

Unless you are willing to do months of experiments with replacement speakers, this is the way to go if the stock speakers have deteriorated foam surrounds, at least on S4s. The rear 6.5s are quite competent for their location and replacements will require a subwoofer to get the bass output these provide. They aren't going to shake the car, but they are matched well to the free-air chamber back there.

Good to hear that you guys like the stock sound again

Awesome, I just ordered 6" speaker foam for mine since they are in pretty bad shape.

I got the kit in the mail yesterday. I had to do some trimming on the foam but the installation was easy. Best advise would be to plan on getting something to press the foam in place till the glue is cured (e.g. 6" PVC pipe). The bolts did not put the desired pressure that was needed but it still cured fine.

The stock speakers sounds absolutely amazing. And I no longer need to add a bazooka tube.

One of the easiest and cheapest fixes in the 928 world.
Listening to music is fun again

Congrats! Glad to hear that you like your "new" speakers!

I did the same repair to my '89 S4 last winter...only I went down to my local electronics depot and matched up a pair of replacment foams for less than $5. That's the cheapest repair I have done to my 928 by far...and quite a "bang" for the buck!

I must say im really not impressed with the stereo in my 89.
Ive tried to play around with the setings and its rubbish.
Im pretty sure my foams ok but thanks to this post ill have a better look.

You just need to practice searching Jim

Public Service Announcement / Idiot alert: Super glue is not an acceptable substitute for the chloroprene- based rubber cement that Springfield Speaker supplies with their surround kit. It and the foam do not shake hands at all.

And if you order re-foaming kits, use them in a few months or so, the supplied glue turns to bubble gum if you wait, er, 3 years.

I think I used yellow contact cement for the last set I did. The kit I found had white glue, somewhat like Elmer's school glue in the bottle. But as Rob notes, the glue "goes away" in storage. Advantage of the white glue is that you can position the cone and foam even after the glue is on there. With contact cement, that option doesn't exist.

The 6" B-pillar speakers in my car have been replaced with some better elements, carefully mounted in the factory housings with the factory grills. The 4" high-mids and the tweeters have been re-foamed though. My workbay is equipped with some many-decades-old dinosaur audiophile speakers that have been through a couple re-foaming exercises now. Two 12" 500W subs took a bit of searching to find support sufficient for the long throw. As Bill Ball suggests, it was an fun project with shims to keep the voice coils centered as the foam was fitted and glued. All in all it's a lot of great results for a minimum $$ investment.
