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 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
By adapting the technologies found in BLADE and REFERENCE, Q Series delivers the experience of both music and film with clarity, depth and detail. The signature Uni-Q driver array, a concept featured on practically every KEF product, dramatically widens the audio ‘sweet spot’, therefore allowing everybody in the room to experience natural, detailed sound. Other features including the damped tweeter loading tube and redesigned auxiliary bass radiators (ABR) further improve levels of detail and bass depth.

Designed for you
The Q Series has an option for everybody and every room. Three floorstanding models and two bookshelf speakers, ensure that no matter the room size or personal preference, the Q Series can deliver an engaging, room-filling experience.

Home Theatre beyond the expectation
The Q Series also brings the magic of cinema sound to your home. The centre speakers, including the powerful Q650c and compact Q250c, provide a perfect tonal match to the main speakers, ensuring a seamless soundstage with voices coming through crisp and clear. The Q250c is also designed to be used as an LCR speaker for positioning in cabinets and alcoves.
The Q50a can either be wall mounted or placed on the top of the main speakers to deliver a convincingly enveloping Dolby Atmos experience for those people that demand the best in cinematic sound. Plus, the Q Series has a perfect partner in the KUBE range of KEF subwoofers for an even more impressive bass performance.

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 black, white and walnut finishes.

Award-winning by nature
Benefiting as it does from technology developed for KEF’s flagship ranges, it is no surprise that the Q Series has been internationally lauded throughout its existence. Representing exceptional value, the latest Q Series has won awards that include What Hi-Fi’s Product of the Year 2017 (Q350) and EISA’s Best Product 2018-2019 for Home Theatre Speaker System.
