Reference Series

With only frequencies above 400Hz to handle, movement of the UNI-Q ® cone is so modest that virtually no distortion is caused by intermodulation with the tweeter. Like the bass drivers, an open chassis design - fully decoupled - minimises acoustic reflection behind the cone.

The result is an even more spacious, better defined sound stage over a very large area, with exceptional off-axis response and none of the ‘sweet spot’ limitations of conventional speakers.

Bass extention is equally stunning, thanks to ultra-low distortion motor systems and high tech reinforced diaphragms. And with each bass driver radiating from its own dedicated enclosure to avoid the distorting effects of vertical standing waves that tall cabinets usually suffer from, you experience noticeably clearer, more open bass.

As you would expect from a handmade KEF product, build quality is as outstanding as the specification of each individual component. Carefully graded and soldered by hand, KEF's own oxygen-free copper cable ensures the best possible signal transmission, with terminals machined from solid brass and plated in gold. High order crossovers with advanced air-cored inductors and polypropylene capacitors ensure faultlessly smooth integration.

For optimum performance in real rooms, all models accommodate tri-wiring and are fitted with a boundary control device to adjust bass response according to speaker positioning and the acoustics of the listening area. Magnetic shielding ensures trouble-free positioning in home theatre applications. Engineered from laminated birch ply using KEF's own internal bracing system, the new curved section cabinets are elegantly profiled to minimise colouration and finished in a choice of hand-matched hardwood veneers. More than ever before, these are very special speakers indeed.
