KEF Q350 2-way Bookshelf Speakers - Award-winning depth and clarity

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

KEF's patented Uni-Q technology places each speaker's 1" tweeter in the acoustic center of the 6.5" woofer. This concentric design allows sounds to originate from a single point source, making the "sweet spot" (the ideal listening position) much larger.

If space is limited the Q350 will not limit your musical enjoyment, a Uni-Q driver and clever port design let it open up the sound. With KEF's signature Uni-Q driver array and a Computational Fluid Dynamics (CFD) port, the Q350s deliver detailed natural sound with high clarity and tight bass.

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.

Q350 is available in satin black or satin white finish. Full-length magnetic grilles are optional

KEF can hold its head up high: the Q350s are a cut above the rest. This level of clarity and refined detail isn’t something we usually hear at this mid-range price – we’re really impressed.
this is a seriously impressive loudspeaker for the asking price. It combines a consistent ability to inform and produce an entirely believable performance with the no less important skill of sounding fun at the same time. The Q350 might best be summarised as 90% of an LS50 for 65% of the asking price and that’s got to be worthy of recommendation.
