Hi everyone. I'm so sorry if this is an 'easy find' but I've tried searching for it and can't find what I'm looking for. I want to find a 'how-to' or a dummies guide on how to cut the 1990 S4 rear woofer surrounds so I can re-use them for new speakers - the round mis-shapen ones rather than the square ones. Can anybody help at all please? Thanks so much
I'm not completely sure I understand your question: are you asking about how to remove the metal part of the speaker grille/cover? Do you want to reuse the round, plastic part?
If you're looking to separate those pieces, there are tabs on the metal part of the grille that are bent over on the inside part of the assembly. If you straighten those carefully you can separate the parts.
There's not really an elegant way to do it since the speaker support frame is integral to the mounting ring. How you cut it depends on how you need to mount the replacement driver in terms of having a flange to attach the new driver to.
Unless you're trying to avoid having a dedicated subwoofer somewhere else in the back, I would look at putting a dedicated subwoofer somewhere in the back. The imaging of the 10-speaker '89-95 systems is a bit of a mess. Put mids and tweeters in the doors, and a sub in the spare tire well and call it done. And there are people that will pay good money for an original 6.5" woofer to return their cars to stock, for resale.
That unsolicited opinion aside, here's an example of a hacked/cut 6.5" woofer surround.
In all honesty, I have done that to a set and regret it. Those are very rare and since Porsche has them as NLA you are better finding something with its grill to install while saving those pieces.
Thanks all for the replies; I took my life in my hands yesterday (OK, slight exaggeration) and set to the rings with a Dremel and am very happy with the results. I agree that these rings should be freely available either aftermarket or 3D-printable.

Checked my records and I bought a pair of those surrounds from an eBay seller called Larkindustries in Texas. They are plastic casts, not 3D printed, and they look like excellent quality. Crazy prices though!

Those look like OE units with the driver carefully cut out.
That's exactly what I directed my shop to do three years ago to make my new woofers fit (see below). They had to do the same procedure for all 10 speakers to allow me to use the OE grills--I like the stock look.
What the shop--Autobahn Performance, Peabody, MA--started with from my 1989 S4 Because of the curvature of the B-pillar, the only way I could make new woofer work was to use trim rings of OE woofers... It looked better when plastic was blown away. Top View Bottom View Top View Side View
