| Content | “Sit anywhere" Uni-Q Sound
At the heart of the evolved Q Series 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 realisation. 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 sound taken to the next level
The closed box midrange cabinet design reduces the load on the Uni-Q midrange cone, increasing clarity and detail while delivering cleaner, punchier bass.
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
Low-frequency (LF) drivers now have a larger roll surround, along with a new spider suspension to produce cleaner bass at high volumes. A new cone structure improves midrange clarity, and an enhanced Auxiliary Bass Radiators (ABRs) with a new surround and rear suspension delivers better controlled and more impressive bass.

Floorstanders
Q750 is the intermediate model for the Q Series floorstanders. Featuring the KEF signature Uni-Q driver array paired with an impressive 165mm (6.5 inch) aluminium bass driver and two matching ABRs, the Q750 combines astonishing sonic reproduction with powerful room filling bass.

Great looking speakers. Have owned in the past and was sad to see you can no longer bi-amp them like the older ones but these still sound amazing. The center image is flawless with the Uni-q drivers and they honesty have nice smooth bass even though it only has one woofer. Excellent sound quality

Got q750 to replace old b&w 601 bookshelf speakers, huge up grade, very happy with the results. Intended to go to a local shop to see some options. Called Eftichis, nice gent on the phone talked me thru the purchase, easy and done. Renewed my interest in the hifi hobby, thank you.
