The larger of the two bookshelf speakers available in the Q Series. The remarkable Q350 speakers excel when space is limited and greater bass is needed. Featuring our signature KEF Uni-Q driver array with Computational Fluid Dynamics (CFD) port design, the Q350s deliver detailed natural sound with high clarity and tight bass. The Q350 have the ability to fill even larger rooms with robust and detailed 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 realization. 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
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.
To optimize the resolution and purity of the Q Series bookshelf speakers, the Uni-Q driver has been repositioned to the center of the cabinet to reduce unwanted internal resonance and adds refinement to their sonic clarity and detail.
CFD Designed Port
Featuring a Computational Fluid Dyanmics (CFD) port design with the port repositioned to the rear of the speaker, clarity is improved by reducing the audibility of the midrange leakage through the port. The geometry of the ports have been tuned to minimize turbelence at higher levels resulting in a reduction in port noise and less LF compression.

Q350 Loudspeaker Review - Stereophile
"Early in this review process I realized that KEF’s Q350 is not the poor person’s LS50, but has a unique goodness of its own...The KEF Q350 is a lively and open-sounding loud- speaker. It delivers appealing tone, taut and satisfying bass, excellent boogie factor, and a feeling of sophistication—all at a very low price. Highly recommended.”
"The Q350s are as versatile as they are remarkable. As a side or rear surround, the Q350 speakers are authoritative, delivering deeper tones for aggressive sound effects and music (there's a reason Dolby adds full range speakers to its theatrical Atmos systems) so you don't need to rely on one or two subs. As stereo or front channel speakers, the Q350s sound like towers; they move a lot of air and are so transparent. Add in a subwoofer, and they're even better. If you don't have the room for towers or want to save money on a Q Series system, the Q350 might be the way to go.”
"From the smart, minimalist design to the insightful, informative sound, the KEF Q350 speakers are the complete package – and the best pair of bookshelf speakers on the market for the money. That’s why they’re a 2017 What Hi-Fi? Award-winner.”
"The Q350 offers an affordable option for those seeking the sonic advantages of the concentric Uni-Q driver. When playing full range at modest volume levels, a pair of Q350s provide an accurate and engaging audiophile listening experience. And when used with a subwoofer and bass management, they become high-performance satellites that can play loud and clean. They are well-behaved and sound neutral without the need for equalization. If you appreciate speakers that don’t “tint” the sound, you’ll enjoy the Q350s.”
"A major highlight of the Q350s is the presentation of vocals. Whether it’s John Lennon, Enya, Bob Marley, Al Jourgensen, Bjork, Elvis, or Lil’ Wayne, there was a verisimilitude to the presentation that qualifies them as Hi-Fi speakers and not merely 'good'.”
