KEF Q Series Q550 Floorstanding Loudspeaker

KEF Q Series brings cutting-edge acoustic technology from ranges such as the legendary KEF REFERENCE and Blade loudspeakers to a wider audience. Representing exceptional value, the Q Series continues to win awards globally by unlocking detail and depth in whatever you choose to listen to.

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, Satin White and Walnut finishes.

“Sit anywhere" Uni-Q Sound

At the heart of Q550 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 realization. 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 to the Next Level

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

Q50a is easily mounted on the wall for a high-fidelity surround sound experience, or placed on top of a speaker for a full Dolby Atmos Theater experience. Its Damped Tweeter Loading Tube produces a detailed and natural high frequency sound, and the styling means the Q50a will blend seamlessly into any interior.

KEF Q550 Cabinet Design

New Cabinet Design

Q Series Floorstanders: The Uni-Q driver has been placed in sealed box within the cabinet. The closed box midrange cabinet design reduces the load on the Uni-Q midrange cone, increasing clarity and detail while delivering cleaner, punchier bass. Midrange clarity is enhanced again through improvements to the mid-bass driver that allowed the DC blocking capacitor to be eliminated. Its removal also created a more natural bass roll-off between the drivers.

Attention to Detail

Q950 and the entire Q Series line is available in three handsome finishes: Satin Black, Satin White and Walnut. Special attention was paid to the plinth and spikes to allow ease of balance and positioning.
