KEF Q550 2.5-way Compact Floorstander

Everybody deserves great sound. Which is why KEF’s Q Series takes cutting-edge acoustic technology from the legendary Reference and Blade series loudspeakers, and delivers them to more people than ever before. Q Series has benefitted from this ‘trickle-down’ approach since it was first launched in 1991, and this 8th iteration has once again redefined ‘entry level’ sound quality. Representing exceptional value, the Q Series continues to win awards globally by unlocking unparalleled detail and depth for loudspeakers in its class.

‘Sit-anywhere’ Uni-Q sound

The Q550 2.5-way floorstander is far more capable than its compact size might suggest, delivering wide bandwidth and full scale with ease. With the KEF signature Uni-Q driver, a 130mm (5.25 inch) aluminium bass driver and two matching ABRs the Q550 delivers phenomenal audiophile performance with clarity and power.

KEF's patented Uni-Q technology places each speaker's 1" tweeter in the acoustic center of the 5.25" woofer. This concentric design allows sounds to originate from a single point source, making the "sweet spot" (the ideal listening position) much larger.

Elegance by design

Designed to blend seamlessly into any home, all Q Series speakers feature a clean, contemporary, and minimalist design. A satin finish to the exterior surfaces imbues them with a premium glow, while the seamless baffle gives them a refined finish. The Q Series has also been designed to complement any room, with tone-matched drive units and a choice of premium quality satin black and satin white finishes.

Q550 is available in satin black or satin white finish. Full-length magnetic grilles are optional
