-KEF R Series R900 Speakers

The distinctive feature of the R900 is the Uni-Q driver, which incorporates certain commendable refinements to the bass drivers to create ingenious, rich sound of superior accuracy to an extent that it meets the standards of KEF's previous R series speakers.

A computer optimized dome and a big neodymium magnet makes the speaker operate over a wide working range. In order to capitalize the Uni-Q's point source features, KEF's upper registers are designed with precision. The tangerine wave guide helps in spreading the higher frequencies across a wider angle evenly to fill the room with natural sound field. Positioned above and below the Uni-Q driver are the twin LF drivers, which deliver superior performance.

A braced aluminium alloy cone provides clean and fast mid-range response. A strong die-cast aluminium chassis prevents the transfer of resonance to the cabinet. On the rear end of the speaker, there are four bass reflex ports. Two of them are near the bottom of the cabinet, and the other two are on the top half. In order to minimize port noise and reduce turbulence, the bass reflex ports are designed using computational fluid dynamics. Another intriguing highlight of the KEF speaker is the heavy vented magnet assembly and a voice coil made of aluminium. The firm and stiff hybrid cone assures deep, uncompressed and clean bass output with superior power handling and dynamics. All the parts of the KEF R Series Speaker operate together as a single unit, thereby delivering accurate, precise sound of superb quality.
