Speaker Repair Shout-Out

Posted by: Jonners on 30 August 2018

After 12 years the rubber membranes surrounding the cones on my Dynaudios were splitting. Dynaudio don't do refoaming kits, they wanted to sell me new drivers at €240 each, plus dealer fitting.

I couldn't find anybody who was just willing to change the membranes until I chanced across a 1-man band in Coalville, Leics called Pro Audio Service. I had to take some measurements but the membranes were ordered in and fitted. It was pretty tricky by all accounts but he did a great job and for £80 I was dad chuffed! 

Rob's an engineer by trade and mostly does electronics so also good for amp repairs.

He's only about 30 minutes from Cymbiosis, which is rather too convenient for my liking ;-)

For a professional service the thing to look up is re-coning, which generic term can cover surrounds and voice coils as well as cones themselves. Some manufacturers do re-cone kits - especially those into professional audio and sometimes parts are sold to the public and sometimes only to the trade. And if the original driver doesn’t do, there are some made for popular drivers by third party manufacturers, though then there may be uncertainty over whether they are to the original spec.

i once had an Altec bass driver reconed because the voice coild was damaged and rubbing, done by a little back-street operation somewhere in london, but it was amazing how many speakers of different types they had in to do when I visited.

And I have repaired three drivers myself: a pair of Peerless midrange units in my IMF TLS50 speakers some time time ago, whose surrounds had perished and gone into holes. I  bought new surrounds with glue and followed the instructions provided. it was a doddle, and the results  performed just as new, as far as I could judge, even though the new surrounds were not claimed to have been made by Peerless. (I have seen what I believe to be the same supplier advertising regularly on eBay). And about 5 years ago I repaired a Scanspeak tweeter using a new diaphragm/VC/surround assembly made by Scanspeak themselves and supplied from stock by Wilmslow Audio - very straightforward. All far cheaper than buying new drivers (and in the case of the IMFs, the same drivers no longer available).

A friend of mine had some spendor Spendor sp1/2 rubber surrounds fall to bits after he got a nap250 DR (lol) got them redone and my goodness what a revolation. Big big bottom end faster but still sp1/2....
