KEF 107.2 with KUBE?

I am the original owner of a very early pair of 103/3s that have always been used with the Kube that came with it. The installation manual makes no mention of the speakers and the Kube being matched but the Kube is labeled on the rear for 103/3. In the 25+years I've had them I don't think the dial has been off the 12 o'clock position a dozen times.
"The Kube is an active low-level equalizer. This equalization forms part of the speakers crossover network and is an essential part of the design."(from the manual)
I would be more concerned with the condition of the drivers-both the woofers and tweeters. Great restoration threads on 107/2s on AK.These were expensive when new and bring big money today.Good luck and happy listening.

There are much better speakers out there now.

All kef reference of that time were matched pairs, if memory serves they were within 1/2 db pairs and 1 db of the standard. the kube was made for models NOT INDIVIDUAL PAIRS. the first kube for the 107 was complex, the later kube's were more user friendly and the 107/2 kube was different than the kube 200 and 100. I just bought a pair of 107/2's and initially forgot to install the kube and must say if you can't hear the difference you really wasted a lot of money. some kef R of that period offered the kube to add deep bass, but the 107 and 107/2 were designed with it.

I understand there were some 107/2 KUBEs with balance XLR connections.  I'd pay $1K for one of those.
