KEF Q550 Floorstanding Loudspeaker
Q550 Floorstanding Speaker

Q550 is the smallest size among the Q Series floorstanders. Featuring the KEF signature Uni-Q driver array paired with a 130mm (5.25 inch) aluminium bass driver and two matching ABRs, Q550 delivers a phenomenal audiophile performance with clarity and more controlled bass.

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

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.

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.

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