First time post, long time KEF owner.
I own 2 pairs of KEF 101.2 Reference Series loudspeakers. They are Type SP3123 and have a B160 SP1271 LF driver with a date of Feb 6, 1991. They are of the Uni-Q variety in that the tweeter is inside the woofer. Does anyone know anything about these speakers? Where can parts be obtained or qualified repairs made. I can find no mention of them anywhere at all.

One of the drivers has a locked up woofer, will not move. One of the other drivers has a damaged tweeter. It is barely audible. Not completely blown, but definitely not as loud as the other three units.

As far as information, I am looking for anything, technical specs, reviews, etc. I believe that these were very expensive for their time and highly rated, but, I just don't know. To me they sound wonderful.

Thanks,
Chuck

Ok, I'll look in my attic store...
Do not hold your breath as a few variants of the B160 exist.
(Good Old KEF!).
I have many gaps in my files, so please be patient.
Give me a couple of days.

Apart from gutting another one of the other Reference Models 102/2, 103/4 and 105/3 which used the same 6.5" chassis I've no idea.
You can get an up to date replacement tweeter directly from KEF but it's expensive, R1584X @ $83.

Thank you. There is no need for any hurry. I have waited this long, I can wait some more. Thanks for your help.

Is the replacement tweeter the same type that will fit in the woofer where the dust cap would normally be?

I have disassembled my ailing 101/2 and have found that the inner magnet is not aligned correctly. The voice coil gap is very big on one side and touching on the other side. The magnet is ruined! In the process of removing the magnet the cone of the woofer became unglued from the spider assy and has a small rip in it. The voice coil is also probably ruined from being squeezed between the magnets and my subsequent removal of the magnet. I am pretty sure that a "speaker reconing service" could make this into a speaker again, but I fear it would not be a KEF speaker, i.e., they would not use the same magnets, surrounds, etc. That is why I came here. To find out if it is possible to have it repaired to original specs. Otherwise I will be shopping for a new speaker system. That will mean spending upwards of $2000.00 to get something comparable, in my opinion. Once again, thank you for your replies and help.

Ok, after braving the confines of the loft sadly only these units were found.

B160 SP1395 Bass (No UniQ Tweeter).
B160 SP1377 Mid with tweeter (unknown).
UniQ Tweeter SP1446
UniQ Tweeter SP1367

Sorry, for the time being nothing to match yours... Crying or Very sad

I really appreciate you looking for me. Thank you. In the end I have 2 fully functioning 101's and 1 spare fully functioning 101 and the last 101 has a weak tweeter and a broken woofer. I only use 2 of them but it would be nice to keep them all repaired and working. I will just keep my eye out for a B160 woofer. On the other hand, maybe it is time to let them retire to the old speaker farm! Thanks, again.
