KEF 107.2 with KUBE?

Hi db

Contacting members is no longer an option since the Audiogon upgrade took place. I saw 2 active listings for KEF 107.2 speakers. You can ask those sellers questions about the 107/2 and the Kube equalizer.

I never saw KEF say their KUBE Equalizers were adjusted for individual speakers I only saw different KUBE EQs for various speaker models. 105/3, 104/2, 103/3 etc etc. Have you tried contacting KEF about the 107/2 and the Kube EQ for it? I've spoken to Corey Medley over at KEF customer service (GP Acoustics (US) Ltd) a couple of times regarding various KEF speakers I've owned or had questions about and they were responsive.

Also I don't see how the KEF Kube EQs would need to be re-calibrated if a re-foam or surround repair was done. Wouldn't that kind of repair return the speakers to original form so no change to the eq is warranted? I would think if you changed the original drivers to an entirely different speaker you would have to modify the Kube.

Well good luck in your search.

J24,

Recalibrating KUBEs when a driver is altered would be necessary only if KUBEs were calibrated for individual speakers, something neither of us thinks is likely.

KUBE -
I AM ABSOLUTELY CORRECT WHEN I SAY THAT EACH KUBE IS CALIBRATED TO THE INDIVIDUAL SPEAKER.
If you can find Dick Olshers review in Stereophile vol 9 no 7, November 1986, he discusses the 107 Kube. He actually had DC offset problems with his 107's Kube.
When contacting the factory Dick was advised that the factory had all the Kube parameters recorded for his specific speakers, which were serial number SN1407, and the factory would be able to build a new Kube for those specific speakers. Each speaker is also marked L for Left and R for Right. This is all documented in the review.
I can only suggest if you still dont believe me, or Dick Olsher, then contact the factory direct and hope that someone there has been there long enough to remember.

Here is Olsher's review in Stereophile

I reread Olsher's review of the 107 in Stereophile. I think I discounted that aspect of it because I suspect hyperbole. Is it logical that contemporaneously built speakers would have such variations, yet the factory could build a given speaker with such precision to match exactly a previously built speaker? If that were so, why then would there be the supposed variation? And lest we forget, those KUBEs have HF and LF gain controls aimed at tailoring the sound to particular placements and room acoustics.

But if I read the review literally, I should be able to send KEF the serial numbers of my 107.2s and get a KUBE made for them. Unfortunately. my 107.2s, like so many others, were reconed with new surrounds in the US. Woe is me!
