Step to the Front of the Queue with the KEF Q350: Acclaimed Bookshelf Loudspeaker Features Signature Uni-Q Array, Plays Music with Revealing Clarity, Detail, and Accuracy
The grille-free KEF Q350 is no ordinary two-way stand bookshelf loudspeaker. Rave reviews from the likes of Stereophile, What Hi-Fi?, and CNET attest to its insightful abilities while KEF technology ensures it performs to spec. Utilizing cutting-edge technology from the company's Blade flagship, it plays with tremendous clarity, reveals incredible detail, throws a wide soundstage, and maintains a natural balance.
It all starts with KEF's signature Uni-Q array, comprised of a 6.5-inch aluminum midrange/bass cone and one-inch aluminum dome tweeter located at the center. A damped tweeter loading tube from the company's fabled Reference Series further sweetens the lower treble performance, enabling Q350 to disappear into the background. What's more, KEF's Computational Fluid Dynamics (DFD) port eliminates chuffing and reduces low-frequency compression common in many two-way monitors. Engineers also used Finite Element Analysis (FEA) to increase Q350's MDF strength and reduce resonances. You'll hear more of your favorite music and soundtracks through Q350 – not the characteristics of the cabinet itself. Relatedly, the inclusion of a low-distortion inductor at the crossover helps make low frequencies sound like they're emanating from a larger speaker.
Weighing in at just under 17 pounds and measuring a modest 14.09 x 8.26 x 12.04 inches (HWD), Q350 can fill a living room or home-theater space with mesmerizing sonics. Whether you favor furniture-shaking EDM tracks or the subtleties of an intimate classical quartet, it soars smoothly at 28kHz elevations while confidently demonstrating that 48Hz feels deeper than you thought it would. Such audiophile-grade touches and versatility allow Q350 to both boogie and waltz.
"The KEF Q350 is a lively and open-sounding loudspeaker. It delivers appealing tone, taut and satisfying bass, excellent boogie factor, and a feeling of sophistication – all at a very low price. Highly recommended."
– Herb Reichert, Stereophile
"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 midrange price – we're really impressed."
– What Hi-Fi?, five-star review
"The relatively affordable KEF Q350 speaker sounds good with almost everything, and offers an excellent sense of depth and space in decent recordings. Fit and finish are superb."

"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 realization. The result is a more detailed, more accurate three-dimensional sound image dispersed more evenly throughout the room than possible with a conventional speaker. Uni-Q's ultra-wide dispersion is further enhanced by KEF's "tangerine" waveguide over the tweeter dome.
KEF Q Series Uni-Q Driver
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 turbulence at higher levels resulting in a reduction in port noise and less LF compression.
