Vintage Speaker Repair

I am looking for someone to repair/replace an EMI bass driver - EMI Model No. 92390AL.

The driver is fitted in a pair of B&W P2 monitors. My right channel speaker has developed a ‘buzz’ - most noticeable at lower volumes and at certain frequencies (typically, speech frequencies).

Would you recommend repair or replacement?

Has anyone undertaken similar repair work? Can anyone point me in the direction of a capable specialist/outfit to undertake such work?

Qutest/Vertere PulseB/282/HC/250/B&W P2

Have you tried rotating the driver through 180 degrees? Sometimes, after years of sitting in one position, a cone can drop slightly and turning it around might stop the buzzing.
If you’re reasonably handy, it might be worth a try.

The reorientation is worth trying. Otherwise if really in need of repair of the driver there’s a place in Wembley (London) that replaces voice coils and cones etc - Google ‘speaker re-cone’ or similar.

Dear IB,
Question: is the substitute cone ( woofer) depending of any type of arrangement , besides physical measures to fixation, in terms of fine tuning with crossover ? Is it necessary to know the frequencies range of the woofer?

( hope made myself understand)

I have a Teqnovox speaker of late 70’s with a torn woofer, so the OP thread interest me.


I can’t answer that. Where original manufacturers’ cones and voice coils are available, I think they use those, but whether and if so how they repair other speakers I have no idea. I once took an Altec Lansing 15" driver to, an the Wembley people for repair of the voice coil, and there was no obvious difference from its pair afterwards:but then it was a pro speaker and although a good few years old there could well have been stock parts available.

A bit different, another time the foam cone surrounds of a pair of Peerless midrange drivers had perished, and I managed to find replacement surrounds (and glue and instructions) on eBay, and they seemed fine afterwards though I couldn’t of compare with the originals. Recone kits are also available, though maybe your Teqnovox is too rare now as none came up when I typed that in.


Indeed. I found / reckon it was difficult to find any kind of info regarding the model/ manufacturer . Probably I need to go a specialist in the matter for further questioning

Thanks for the help

I would definitely second trying the main driver rotated by 180 degrees. This can often cure odd rubs and buzzes with really old drivers. Once rotated, leave them overnight, then try the next day.

Definitely worth a try, the frame or ‘spider’ can sag over time on some driver designs which deploy big magnets.

Thank you for reminding me of the ‘trick’ with rotating the speaker!
This particular bass driver, the EMI 92390AL, is of an oval construction, and probably partly for that reason I’ve had to rotate it a few times over the past 10-15 years. Unfortunately, it is now at a point, I think, where some more drastic measures are required… and so I’m looking into a possible reconing.

Thank you for this tip! I’m at the moment waiting for a reply from a Wimbledon-based specialist who is probably the person you refer to.

Although having rotated the speaker several times in the past - with reasonable success - I have not let it rest overnight as suggested before testing it - might be worth a try… thanks!

Thank you - I think this particular model - being quite large and oval - might be prone to this type of problem…?

Hmm, that must be another repairer: Wimbledon is south of the river. I have just googled and the one I was thinking of is called Wembley Loudspeaker, but actually situated between Acton and Shepherd’s Bush.

My mistake! Doh!! The person I have contacted is indeed Wembley Loudspeakers :slight_smile:
I really appreciate you comment, thank you.
