I have owned a pair of KEF Cadenzas since new and they still work great today. Recently I have been trying to remember exactly when I bought them. I think it was around 1971 but it is so long ago ! I remember I had a summer job and worked that summer to earn enough to buy them ! There is no indication of year of manufacture on mine, I just have the two serial numbers.

So when did KEF starting making Cadenzas and when did they switch from foam to rubber for the BD139 surround. I obviously have one of the latter types as it still working !

Ta v much,
Andrew

From the "A History of Kef Drive Units" thread.

KEF's records give answers of 1970 and 1972 to your questions.

Although with Terry's pair being from 1973

http://www.hifiloudspeakers.info/Anatomy/SpeakerSystems/Cadenza/Cadenza.html

I would suggest a date between late 1973 or early 1974 for the SP1042.

I don't care if I'm wrong, I only collect (and have an interest in) KEF based systems from 1975 to ~1986 Very Happy .

Hi Colin,

Thanks for that. 1972 sounds OK but 1973/4 sounds too late I think, but I could be wrong too. Perhaps I could compare my serial numbers with Terry's ?

Hmm, maybe I am miles off think 1973. One of my SP1024 serial numbers is 59889 - I can t get to the other just at the moment but it is close to that one.

I wonder if I contacted KEF they could tell me the date of manufacture from the serial numbers ? I am even more curious now ...

Terry's other pair 51224 and friend appear to be from 1975 according to the drive unit date stamps.

No, they're not like Quad Service.

You'll just have to remove a tweeter and read the ink date stamp or the SP1022 or SP1042 and read the date code label like the rest of us mortals and add a couple of weeks.
