Default Woofer for old (1996 or 97) KEF uni-Q 50 (new member)?

I am new and every single person on this website know more than me about audio and systems.

I just set up my old KEF uni-Q 50s and there is a buzz in the left woofer.

Then I looked at the screws around the woofer front.
I have never seen a screwdriver that would fit this screw.

Has anyone out there these vintage speakers and know how to fix or replace a woofer?

I wrote a repair contact in NJ from the KEF site just now too.
Then I thought to try here....

Hello rachelrose, post a picture of the front of the speaker, clearly showing the screw. That way someone can figure out what type of screw it is and give you the answer as to what screwdriver you need.
I would guess that the repair shop could either fix the current driver or provide you with a new replacement.

Each manufacturer goes for his own type of screws, so that only him and his technicians have the factory tools to provide for a repair. Because of size, type of head, strength and thread standards, and market of course. There's also the IMPERIAL and the METRIC systems to choose from.
Best standard known and used is the Allen keys (for internal hex. screws and bolts with socket, Unbrako type - Hex driver/Allen wrench or Allen key) and Phillips, wood, type of screws.
Unified Thread Standard - Wikipedia, the free encyclopedia
When a Phillips is not a Phillips!

Default Thanks for help with KEF uniQ50 woofer

Thank you all-
for answering a dumb question - we must stumble in off the street to diyaudio every so often.... nonetheless

You woke me up!

I found Dan, Dr. Audio in San Luis Obispo who called me back in 2 minutes, gave me things to think about, insight, said these parts are still available, though the speakers are old. I will take speaker to him to fix and answer Qs.

I think you are also right about the proprietary screw head.
Had it been a more typ. philips, hex, star, square or any type for which I have tools, I would have had that speaker apart and probably done more damage.

I post pics, just in case another like moi stumbles in with a buzzy KEF.

I saw similar series pair for sale on ebay just now. The description says "original" but my original woofers don't have the KEF logo on them like the "for sale" woofer - only the tweeters.
The grille for that part of the speaker for sale is "missing".
It looks like somebody had the same issue as I and tried to replace.

Thank you!

I will keep reading and marvelling at the knowledge here of all things audio.

Default kef issue

The screws look like Torks bits. Possibly a #15.

If you have to replace the driver, check with Larry @ Madisound also.

Good luck.
