KEF Q550 Floor Speaker 2 and 1/2 Way 15-130W 87dB 5.25inch Black

“Sit anywhere" Uni-Q Sound

At the heart of the evolved Q Series is the Uni-Q driver array. KEF\'s signature innovation places the tweeter in the acoustic center of the midrange cone, bringing the acoustic ideal of a single point source closer than ever to realisation. The result is a more detailed, more accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with a conventional speaker. Uni-Q\'s ultra-wide dispersion is further enhanced by KEF\'s \'tangerine\' waveguide over the tweeter dome.

Uni-Q sound taken to the next level

The closed box midrange cabinet design reduces the load on the Uni-Q midrange cone, increasing clarity and detail while delivering cleaner, punchier bass.

With the addition of the Damped tweeter loading tube providing a gentle termination of sound produced from the back of the tweeter, lower treble performance is improved dramatically and a new low-distortion inductor on the crossover provides cleaner bass response.

Redesigned Bass Drivers

Low-frequency (LF) drivers now have a larger roll surround, along with a new spider suspension to produce cleaner bass at high volumes. A new cone structure improves midrange clarity, and an enhanced Auxiliary Bass Radiators (ABRs) with a new surround and rear suspension delivers better controlled and more impressive bass.

Floorstanders
The Q550 is the smallest floorstander in the Q Series line. Featuring KEF\'s signature Uni-Q driver array paired with a 130mm (5.25 inch) aluminium bass driver and two matching ABRs, the Q550 delivers a phenomenal audiophile performance with clarity, scale, and controlled bass. Great for large or small rooms the Q550 is available in Satin Black or Satin White finishes. Priced as a pair.
