Q350 Bookshelf Speaker Pair

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.

"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, 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.

KEF Q Series Uni-Q Driver Updates Q350Uni-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.

 "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'.”
