Product Features
"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.

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.

KEF Q Series Speaker Cabinet Updates Q750 New Cabinet Design

In our newest line of Q Series Floorstanders the Uni-Q driver has been placed in sealed box within the cabinet. 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.

  1. Incredibly balanced/neutral & very high resolution
    Incredibly balanced/neutral & very high resolution

    Bass is tight and punchy, mids are neutral and the highs/resolution is exceptionally good for a speaker at this price-point! Example, when listening to John Mayers - Gravity live (where the light is) you can hear the 60hz cycle noise from the lights/equipment/amps etc on stage as if he was playing 6 feet in front of you. With other speakers/headphones you may pickup a fraction of this detail in the song but nowhere clear as the Q750's.

    Massive sound-stage and pinpoint imaging. They throw an amazing holographic/3d sound-stage, sometimes it feels like i left my surround sound on when i'm playing 2.0 channels. (placement is crucial here though)

    They really love/shine with quality power (150w +) but they do an adequate job with 80w as long as you're not pushing the volume. The more/quality power you feed the better it gets with Q750's.

    Extreme basshead's may want to look at the Q950's but "audiophiles types" will be very contented with the Q750's bass output. I love deep/punchy/clean bass but i wouldn't consider myself a "bass-head" and the Q750 makes me smile!

    This is the most balanced/neutral speaker i have ever listened to and i mean that in a positive way. The Q750 won't add color to your sound and are true to the recording.

    overall i'm 100% satisfied with these and can't wait to add a couple mono-block amplifiers behind them!

Q750 Floorstanding Loudspeaker - Review and Reviewer's Choice Award Soundstage Access
"KEF’s Q750 is a superb loudspeaker. It’s one of the most neutral transducers I’ve ever heard, and for the money offers staggeringly transparent sound. I fed it a steady diet of male and female singer-songwriters, and was always satisfied with the authenticity of what I heard. It’s not exactly a looker, but it’s well engineered, and sounds far more expensive than its price suggests. If I had $1500 to spend on speakers, this is what I’d buy. I’m not sure I can pay KEF’s Q750 a higher compliment.”
