While we're all praising/damning old KEF drivers, does anyone
remember the T15?
Any opinions? It's a large dome tweeter crossed over at 1kHz.



My memory of it was in the transmission line speakers designed by Dr
Arthur Bailey of Bradford University and the subject of an article in
Wireless World in 1972.

A colleague of mine built a pair and he sold them to me when he got
married and moved into a smaller house in about 1977. The T15 by then
was obsolete and a T27 was used to which I later added a Coles 4001
super tweeter. By today's standards the imaging was not so good but
you could rattle windows at ten paces with the clear, solid, and
immensely natural deep bass - you have never heard organ pedal reeds
like it!

Sadly I had to disassemble them about 20 years ago as Management was
getting fed up with the size, but I still have the drivers.

The nearest commercial equivalent was the TLS80, and in a different
case a Cambridge speaker, ISTR the R50.

All very well but what about the T15?
I acquired a pair of KEF Cantata G4s and can't live with them,
even in the garage, so they'll be on ebay after Christmas.
Unless I decide to give them another chance and re-use them with an
active crossover, as they look very nice with the mirrored domes.

We've all built transmission lines with Cambridge R50 crossovers.
It was a rite of passage....
