Q350 Bookshelf Speaker
Two-way bookshelf
If space is limited the Q350 will not limit your musical enjoyment, a Uni-Q driver and clever port design let it open up the sound.
With KEF's signature Uni-Q driver array and a Computational Fluid Dynamics (CFD) port, the Q350s deliver detailed natural sound with high clarity and tight bass.
Priced as a PAIR.
Magnetic grilles sold separately.



A new cone structure improves midrange clarity and an enhanced Auxiliary Bass Radiator (ABR) with a new surround and rear suspension enhances bass quality.

Amazing design!Moving Klipsch floor standing speakers to my store, and needed a smaller set to better fit my room. Wood grain color complements my vintage Sansui, as well as bring out the timbre of most electronic LPs. Definitely will purchase a home theater set for my Yamaha!
Why would a grill be extra?Posted on

Great!These speakers are among the best in class in this price bracket. For me, they sound wonderful.
Clear, precise, easily integrated with other components.
They look stunning too. I understand why they're not shipped with covers, who want to cover that lovely face!?
Please note they're quite deep for a bookshelf speaker, if you're looking for something compact...Posted on

Stereophile Recommended Component 2019 |
"The Q350 is also slightly more sensitive—87dB vs 85dB—and its crossover network is characterized by gentler filter slopes and, concomitantly, a lower parts count. Although HR preferred various aspects of the performance of the more expensive KEF—in particular its "more forceful and detailed" bass and its "balanced purity"—he found himself admiring the Q350s for their "above-average force and texture" and their lively, open, consistently "direct" sound. Herb's conclusion said it all: "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.” |

Q350 Speaker Review |
"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.” |

Q350 Speaker Review |
"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.” |

Q350 Product of the year award - What Hi*Fi? |
"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.” |

Q350 AVS Forum Best Speakers of 2017 |
"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.” |

"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 mid-range price – we’re really impressed." |

Q350 Speaker Review |
"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'.” |
