KEF Reference Model One loudspeakers

 Reference Series Model One (1994-99)

Model One was a three-way floor standing system with a single unit coupled cavity bass section. It offered refined musical reproduction in a compact enclosure. It could be used as a main speaker in small to medium sized rooms or as a rear speaker in a multi-channel system with one of the larger models at the front.

From the full three-way, three driver design with computer matched crossover to the coupled cavity bass loading. Model One are the very essence of all that we have striven for with our Reference Loudspeakers. They are perfectly suited to the smaller listening environment.

An Ability for Compatibility

Please don't think that just because we design and build KEF Reference Loudspeakers to such high standards that they are only suitable for critical applications like recording studios. Features like magnetic shielding and tonal accuracy make them ideally suited to home theatre systems. And unlike some so called "high end" products, they are quite at home with more affordable electronics. But of course, with loudspeakers of this calibre, the exceptional performance of more esoteric equipment is fully realised.

Every Part Perfect

Any loudspeakers is only as good as the sum of its parts. That's why, at KEF, we set rigorous standards for each and every component of our Reference Loudspeakers.

Just one example of this attention to detail is the Oxygen-Free Copper (OFC) internal wiring. Different gauges for bass, mid-range and high frequency drivers ensure maximum information transfer room even the most delicate of signals and as you'd expect, we hand solder these cables to further improve sonic integrity. At the rear of the loudspeakers, the internal wiring joins heavy gold plated terminals with a bi-wiring option.

Even the plinths are examples of KEF's commitment to excellence. Mineral filled and formed from rigid polymer, they can be removed and filled with lead shot for additional stability. The elegant feet are turned from solid brass then heavily plated with gold. reversible and adjustable spikes are fitted to give excellent results on a variety of floor surfaces.
