WARNING:
From the manufacturer
The remarkable Q Series bookshelf speakers excel when space is limited. Featuring the 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. A powerful 6.5 in. driver delivers deep powerful bass perfect for movies, television, and music.
"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.

Uni-Q sound taken to the next levelWith 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 PortFeaturing 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. |
Q Series OptimisedTo optimise the high resolution sonic image of these speakers we re-positioned the Uni-Q driver at the centre of the cabinet.This avoids any possibility of standing waves and reduces resonance within the enclosure. By facing the low frequency port to the rear we reduce the audibility of midrange leakage. |

Product Description
The KEF Q350 bookshelf speaker, the bigger brother of the KEF Q150, incorporates and successfully builds upon everything KEF fans have come to know and love about the bookshelf speaker. The New Q350 boasts a revamped Unit-Q driver array with a damped tweeter loading tube designed to smooth out treble frequencies, and reimagined crossovers to provide cleaner and more accurate bass. Architecturally, the Q350 benefits from a New port, which has been moved to the rear of the speaker to improve audio clarity, and the Unit-Q driver array has been relocated to the middle of the cabinet to reduce unwanted internal resonances. These changes between the Q300 and Q350 have transformed an already breathtaking bookshelf speaker into one that truly needs to be heard to be believed. The Q350 is available in sleek matte Black and white vinyl finishes. Grilles for the Q350 are sold separately.

Soundstage: wow wow wow, did I say wow? These suckers soundstage better than ANY speaker I've listened to, which is really hard for me to grasp. No matter the placement (we'll get to that!), Soundstage is on point and EXTREMELY wide.
Bass: let me just say, I am a huge advocate for a small sealed subwoofer with any system. However, you COULD run these without a sub if you're really on a budget. In my room and 14in from the back wall, the Q350s sing all the way down to 45hz!!! (Then they fall off hard) But 99% of music never even reaches down that far. But more important to me, the bass is extremely clean and clear, being a 6.5 woofer. It is also extremely present and punchy, and I did have to EQ off a little of the low end since it seemed over balance the mids.
Build: though not as solid is some other speakers I've owned, the Kef Q350s are absolutely stunning, even more so in real life. The finish is a really nice texture, and welcomed break from the over-poluted fake wood vinyl that nearly every speaker sports these days.
Treble: despite what I've heard and read, the upper end of these speakers is very detailed. They are definitely warm speakers, so "S" "P" and high hats are a little "rounder" for a lack of a better word. But female vocals are very crispe and breathy enough for me. Too much "detail" and you get fatiguing speakers, and I think kef got the treble just about right for the Q350s.
So what don't I like about these speakers so far? Well as everyone warned me I'm the internet, placing these speakers is NOT FUN!! They have a sweet spot that they like, and probably rooms that they don't like. They aren't very forgiving with placement, and I'm sure that causes most of the negative reviews (which is probably something they won't admit I'm their reviews, haha). As a helpful reference, I have my 350s intersecting at a relatively standard 2-3ft behind my listening position. They are 14in from the back wall, and I sit relatively close to my back wall. They are also quite far apart from each other in comparison to how close I am to them. They need a fair bit of toe in compared to what I do for most speakers in this room.
So basically if you are tempted to buy these, do it! You won't be disappointed. And if the Q350s are a little high on price for you, I'd imagine the Q150s are an even better deal for $300!
After much critical listening I decided to keep these.
Their precision and detail are simply better and more exact than the others. Their imaging is remarkable. And aside from that, they simply sound more beautiful. Like the difference between a really nice Yamaha piano and a Steinway. The sound is richer. The notes resonate better.
My second favorite was the Elac Unfi 2.0. Really great also. But didnt quite have as good separation as the Q350s. The KEFS also have a comforting sound. That’s why I use the term “warm”. It’s not that it is colored. It just sounds more real. (Like the difference a tube amp makes. Just more realness.)
As many reviews have mentioned, these speakers will sound pretty different depending on how you position them in the room. I intend to try many more configurations as time goes on to see where they work the best in my given space. These speakers have a very strong centering of the vocals. I wouldn’t mind diffusing that a little bit if I can. Ive already heard that I can alter that a bit by placement changes.
I’m running these with an Elac 10” subwoofer which fills out the sound nicely at the bottom. I may try another woofer to get a faster tighter bass hit in the future.
I use Qobuz and stream high bit rate files whenever available. Definitely ups the game well beyond typical streaming (Spotify)
I will report back on this review after Ive “broken them in” (Some people claim this opens the sound stage over time. It may simply be a placebo effect or my own hearing re-learning what to expect from the given sound source. We shall see...)
At close range with a bit of toe-in, these speakers are like listening to giant studio-grade headphones. The exactness is thrilling. Like headphones without anything clamping your head. 😁
Oh, and looks wise, they are very elegant. Unique.
So far I’m digging these KEFs 👍🏻

So far I’m digging these KEFs 👍🏻
I've tried:
Klipsch RP-600M - didn't like them at all
Triangle BR03 - liked them, but when comparing side by side with KEF, Triangles sounded more fatiguing.
ELAC DBR62 - liked these too, but similar to Trangles, when comparing side by side with KEF, Elacs were more fatiguing.
I have a very lively room which echoes and does not have a lot of acoustic treatment in it.
However KEF seem to handle it just fine, without getting obnoxious.
Another plus is the bass, I really don't need a sub-woofer with these speakers. Its not your boombox or car type of a bass where you hear it thumping across a lake, its a good proper base to the drums and instruments, giving them weight and more of a body.
Sound staging is really good, very wide.
Sweet-spot is really good too. I was getting annoyed with the other speakers that I've listed to, where if I moved my head literally just a few inches to either side from the exact focus center, the sound would shift dramatically to the side. So I had to be locked into that position to enjoy a center stage. These speakers are a lot more forgiving and you still enjoy them even with another person sitting next to you, which offsets your center position quite a bit.
Really enjoying these speakers.
Top reviews from other countries
As caixas novas evoluíram demais, e acredito que não retorne para o mundo vintage em relação às caixa. Estou muito, mas muito satisfeito com a qualidade que as KEF's estão entregando. Menor ruído, menor percepção de discos riscados, maior definição, som aveludado, presença maior, palco sonoro maior, e separação dos canais soberba. Ganha EM TUDO das minhas caixas antigas. Dentro deste valor, acredito que seja a melhor escolha do mercado.
Los graves son mejores con el puerto trasero abierto y suena más bajo que la especificación a 63 HZ.
La mejor característica de los altavoces es el escenario de sonido, me encanta el jazz lounge y música que tiene bajo sin embargo y para mi sorpresa toda la música suena genial, desde clásica, pop, electrónica hasta el jazz o instrumentos de viento. Lanzan un sonido profundo y con una amplitud del centro. El escenario se extiende más allá de los altavoces, muy buena separación y claridad.
Tienen una excelente respuesta fuera del rango directo cuando estén espaciados al menos a 6 pies de distancia, ya que el sonido se expande con facilidad después de los 6 Khz me supongo esto sucede por tener el tweeter en la parte central.
En mi caso probé con mis bocinas Bowers and Wilkings 606, Elac B 6.2 y Margules Magenta sin embargo estas KEF Q350 en mi apreciación y gusto son las que más me han gustado.
Si estás en la búsqueda de Bocinas superiores a las de entrada, súper recomendadas estas KEF Q350.
