When KEF was founded in 1961, by Raymond Cooke and a small group of likeminded colleagues, the prime
objectives were to design loudspeakers using the latest materials technology and with the best engineering
methods. The 1960s was a hotbed of innovation in drive unit technology with significant contributions from a
number of commercial companies as well as the BBC’s Research and Design departments.
The first drive units designed and developed by KEF formed the K1 series of products. They comprised the
B1814 bass unit, with a flat diaphragm of polystyrene with aluminium foil laminated to the front and rear
surfaces, the M64 elliptical midrange with the same polystyrene/aluminium foil laminate structure, and the T15
tweeter with a dome made from aluminized melinex. The early brochures make a point of emphasising that all
drive units in KEF loudspeakers have diaphragms of synthetic materials. Most loudspeakers at the time had
diaphragms made of paper compounds, which could suffer from sound colouring resonances, sensitivity to
climatic conditions and batch-to-batch variations in production; and the thought was hat plastic materials ought
to offer significant advantages. The fact that bextrene and later polypropylene came to dominate the market for
serious Hi-Fi drivers pays tribute to this vision. Credit ought to be given also to those who continued to develop
the technology behind paper and fabric diaphragms as they now have an equal standing
with plastics and metals in high-end audio. Hot on the heels of the B1814 came the B139 (13 by 9.25 inches in
size), probably the most famous of the KEF drive units. Again the diaphragm was polystyrene with aluminium
foil laminated to the front and rear surfaces. Its midrange performance was just about good enough to integrate
directly with the T15 tweeter allowing the K2 series of 2-way products to be designed including the Celeste and
