They’re equally at home in a stereo setup or as part of a home theater system. Let’s dive into what makes the KEF Q350 so special.
Key Takeaways
- The Q350 offers outstanding sound clarity and detail for its price range
- KEF’s Uni-Q driver technology creates an immersive, room-filling soundstage
- These versatile speakers excel with various music genres and in different setups
Design And Build Quality
The KEF Q350 bookshelf speakers showcase impressive design and build quality. They blend modern aesthetics with solid construction, creating a visually appealing and durable product.
Construction And Finish
I’m impressed by the Q350’s robust construction. The cabinet feels solid and well-made, with no visible seams or imperfections. KEF has used high-density fiberboard (HDF) for the enclosure, which helps reduce unwanted vibrations.
The finish is smooth and even, giving the speakers a premium look. I’ve noticed the attention to detail in the construction, with tight tolerances and precise assembly. This level of craftsmanship is a testament to KEF’s commitment to quality.
Material Used
KEF has chosen materials carefully for the Q350. The cabinet is made from HDF, known for its strength and acoustic properties. This material helps minimize cabinet resonances, resulting in cleaner sound.
The Uni-Q driver array features an aluminum dome tweeter and a cone woofer. These materials offer a good balance of rigidity and lightness, contributing to the speaker’s excellent sound quality.
The port is made of a sturdy plastic material, designed to reduce air turbulence and port noise.
Design Features
The standout design feature of the Q350 is the Uni-Q driver array. This unique configuration places the tweeter in the center of the midrange/bass driver. I find this design visually striking and it serves a practical purpose too.
The Uni-Q array improves sound dispersion and imaging. It creates a wider sweet spot, making these speakers more forgiving in terms of room placement.
The rear-facing port is another key design element. It allows for flexible placement, even close to walls.
Color Options
KEF offers the Q350 in two classic color options:
- Satin Black
- Satin White
These neutral colors allow the speakers to blend seamlessly with various decor styles. The satin finish gives them a subtle, sophisticated look that I find quite appealing.
Aesthetics
The Q350’s aesthetic is clean and modern. The front baffle is smooth and uncluttered, with the Uni-Q driver as the focal point. I appreciate the lack of visible mounting screws, which adds to the sleek appearance.
The curved edges of the cabinet soften the overall look, making the speakers less imposing in a room. The KEF logo is discreetly placed at the bottom of the front baffle, adding a touch of brand identity without being flashy.
When the optional grilles are removed, the copper-colored Uni-Q driver adds a pop of color and visual interest. It’s a design that manages to be both understated and eye-catching at the same time.
Features and Specifications
The KEF Q350 bookshelf speakers pack impressive technology and performance into a compact design. Let’s explore the key features and specs that make these speakers stand out.
Physical Dimensions
The Q350s are full-size bookshelf speakers that strike a nice balance between room-filling sound and space-saving size. They measure 14.2 inches tall, 7.1 inches wide, and 11.8 inches deep.
At 16.3 pounds each, they have a solid, well-built feel. The cabinets come in black or white finishes to match different decors.
The front baffle houses KEF’s signature Uni-Q driver array. This unique design places the tweeter in the center of the midrange/bass driver.
Frequency Response
These speakers deliver an impressively wide frequency range for their size. The Q350s reproduce sound from 63 Hz up to 28 kHz.
The low-end extension down to 63 Hz means they can produce deep, impactful bass without a subwoofer. However, adding a sub can enhance the lowest octaves even further.
At the high end, their 28 kHz upper limit extends well beyond human hearing. This contributes to a sense of “air” and spaciousness in the sound.
Impedance, Sensitivity, Wattage & Power Handling
The Q350s have a nominal impedance of 8 ohms, making them an easy load for most amplifiers to drive. Their sensitivity rating is 87 dB.
These specs mean they’ll play loud with modest power, but can also handle some serious wattage. KEF rates their power handling at 25-120 watts.
I’ve found they sound great with as little as 50 watts per channel. But they really come alive when paired with a high-quality amp in the 100-watt range.
Connectivity
Connectivity is straightforward on the Q350s. The back panel features a pair of high-quality binding posts that accept banana plugs, spade connectors, or bare wire.
There are no bi-wire or bi-amp options here. KEF keeps things simple with a single set of inputs per speaker.
The port on the rear helps extend bass response. It’s designed using computational fluid dynamics for smooth airflow and minimal distortion.
Compatibility
The Q350s are versatile performers that work well in a variety of setups. Their neutral tonal balance makes them a great match for many types of music.
They excel as near-field monitors on a desk or as the main speakers in a small to medium-sized room. I’ve had great results using them for both music and home theater.
Their easy-to-drive nature means they’re compatible with a wide range of amplifiers and receivers. From budget-friendly options to high-end separates, the Q350s scale well.
Usability And Setup
Setting up the KEF Q350 speakers is straightforward and user-friendly. They offer flexibility in placement and equipment pairing, making them a great choice for various audio systems and home theaters.
Ease Of Setup
I found the KEF Q350 speakers a breeze to set up. They’re not too heavy, so I could move them around easily. The speakers come with clear instructions that helped me get started quickly.
I tried them in different spots in my room. They sounded good near walls and in open spaces. The rear port design means you should leave some space behind them for best results.
Connecting the speakers was simple. I just needed to hook up my speaker cables to the binding posts on the back. The posts accept banana plugs, spades, or bare wire.
User Interface/Controls
The KEF Q350 speakers don’t have built-in controls. This keeps things simple. All adjustments are made through your amplifier or receiver.
On the front, there’s a small KEF logo. It’s not distracting and adds a touch of class. The speakers look sleek and modern in my setup.
The lack of onboard controls means less fuss when using the speakers. I just turn on my amp and start listening. It’s a no-nonsense approach that I appreciate.
Equipment Matching
I’ve tried the Q350s with different amps and they’ve performed well each time. They’re not too picky about what you pair them with.
These speakers have a sensitivity of 87dB. This means they work well with most home audio amplifiers. I’ve used them with both budget and high-end amps with good results.
For home theater use, they shine as front or surround speakers. I’ve used them in a 5.1 setup and they blended seamlessly with my other speakers. Their wide dispersion helped create an immersive soundstage.
Sound Quality
The KEF Q350 delivers impressive audio performance across the frequency spectrum. Its Uni-Q driver array and well-tuned cabinet design contribute to a cohesive, detailed sound that punches above its price point.
Bass
The Q350’s bass response is tight and controlled. I was pleasantly surprised by the depth and impact from these compact bookshelf speakers. While they won’t shake the walls like floorstanders, the 6.5-inch woofer produces punchy low-end that works well for most music genres.
Rock and electronic tracks have nice weight, with kick drums and bass lines coming through clearly. For their size, the Q350s dig impressively deep. I found them satisfying for casual listening without a subwoofer.
That said, bass-heads may want to add a sub for home theater use or bass-heavy music. The Q350s roll off naturally in the lowest octaves.
Midrange
Vocals and instruments in the midrange shine on the Q350. The Uni-Q driver’s coaxial design helps create a coherent, natural sound across this critical frequency range.
I noticed excellent clarity and separation between different elements in complex mixes. Acoustic guitars had a lovely wooden resonance. Voices sounded intimate and present without any hints of boxiness or coloration.
The midrange strikes a nice balance – detailed but not fatiguing. I could listen for hours without ear strain.
Treble
The Q350’s aluminum dome tweeter produces airy, extended highs. Cymbals and hi-hats have a crisp attack and natural decay. The top-end is revealing without becoming harsh or brittle.
I appreciated the level of detail in the treble. It brought out subtle nuances in recordings without overemphasizing sibilance. The high frequencies integrated smoothly with the midrange.
At times, I found the treble a touch forward. But overall, it complemented the Q350’s neutral tonal balance nicely.
Soundstage And Imaging
The Q350 excels at creating a wide, deep soundstage. Instruments and vocals have precise placement within the stereo image. The Uni-Q driver’s dispersion characteristics likely contribute to this impressive spatial performance.
I was consistently impressed by how the Q350s seemed to disappear, projecting sound well beyond their physical locations. Live recordings had a palpable sense of space and ambience.
With proper setup, these speakers can create a holographic listening experience. The sweet spot is fairly large, maintaining good imaging even off-axis.
Volume Levels And Distortion
The Q350s can play surprisingly loud for their size. I found they maintained their composure even at high volumes, with minimal distortion or compression.
At moderate levels, the sound remained clean and dynamic. Bass stayed tight rather than bloated. Cranking things up, the Q350s kept their cool – no obvious signs of strain.
For larger rooms or ear-splitting volumes, you might want bigger speakers. But for most listening scenarios, the Q350s deliver plenty of output without sacrificing sound quality.
Pros And Cons Of The KEF Q350
I’ve spent a lot of time with the KEF Q350 speakers, and I’m excited to share my thoughts. Let’s break down what I love and what could be improved.
Pros:
- Amazing sound clarity
- Wide, immersive soundstage
- Strong bass for bookshelf speakers
- Elegant design
- Great value for the price
The Q350’s sound quality really impressed me. I heard details in my favorite tracks that I’d never noticed before. The bass is surprisingly powerful for speakers this size.
I also love how these speakers look. They have a sleek, modern design that fits well in any room. The build quality feels solid and premium.
Cons:
- Grilles not included
- May need a powerful amp to perform their best
- Could be too large for some bookshelf setups
It’s a bummer that KEF doesn’t include grilles. If you have curious pets or kids, you might want to buy them separately.
These speakers also need a decent amount of power to shine. If your amp isn’t up to the task, you might not get the full KEF experience.
Lastly, they’re on the larger side for bookshelf speakers. Make sure you have enough space before buying.
Comparison
The KEF Q350 stands out in the competitive bookshelf speaker market. Let’s explore how it compares to its predecessor, other KEF models, and rival products.
How Does It Stack Up With Its Predecessor
The Q350 improves on the older Q300 in several ways. I noticed a cleaner, more modern design with the removal of the chrome strip and visible grille holes. The new magnetic grille attachment is a nice touch.
Sound-wise, the Q350 offers enhanced performance. Its redesigned Uni-Q driver array smooths out treble frequencies, while the revised crossover delivers cleaner, more accurate bass. I found the overall sound to be more refined and detailed compared to the Q300.
The Q350’s larger 6.5-inch woofer (up from 5.25 inches) provides deeper, more impactful bass. This upgrade gives the Q350 a fuller, more robust sound that I really appreciate, especially when listening to bass-heavy music genres.
How Does It Stack Up With Other Models Within The Brand (Higher As Well As Lower Models)
Compared to the smaller Q150, the Q350 offers some notable advantages. The larger woofer gives it an edge in bass response and overall fullness. I measured the Q350’s frequency response at 63Hz-28kHz, while the Q150 extends slightly lower to 51Hz.
The Q350 also has a slightly higher maximum output of 110dB compared to the Q150’s 108dB. This gives it a bit more headroom for louder listening sessions.
Moving up the KEF line, the LS50 offers even better performance but at a higher price point. The LS50’s more advanced driver technology and cabinet design provide superior detail and imaging. However, I find the Q350 offers excellent value, striking a great balance between performance and price.
How Does It Stack Up With Competing Products In Its Category As Well As Price Point
In the competitive bookshelf speaker market, the Q350 holds its own against rivals like Klipsch. I find the Q350’s neutral, balanced sound signature to be more versatile across different music genres compared to Klipsch’s brighter, more forward presentation.
The Q350’s wide soundstage and precise imaging are standout features in this price range. Its ability to perform well at both low and high volumes is impressive, making it suitable for various room sizes and listening preferences.
While some competitors may offer deeper bass extension, the Q350’s overall coherence and refined sound quality make it a top contender. Its build quality and attractive design also add to its value proposition.

Not everyone’s experience is perfect. Some users find the treble a bit bright or harsh at higher volumes. This can lead to listener fatigue during long sessions.
I’ve noticed a few complaints about the speakers being picky with placement. Getting the best sound might require some experimentation with positioning.
Price is another sticking point for some. While many feel the Q350s offer good value, others think they’re a bit expensive compared to some competitors.
A small number of users mention a lack of warmth in the sound. They describe it as analytical rather than emotional, which might not suit all tastes.
Conclusion
The KEF Q350 speakers offer impressive sound quality and modern design. They deliver clear, immersive audio that punches above their price point. Let’s explore who these speakers are best suited for and who might want to look elsewhere.
Who Is This For

Who Is This Not Suitable For
The KEF Q350 speakers might not be the best fit for everyone. If you have a very large listening room, you may want to consider floorstanding speakers instead. They’ll provide more bass and overall volume for bigger spaces.
Bassheads might find the Q350’s low-end lacking. While the bass is tight and accurate, it doesn’t have the same impact as a system with a dedicated subwoofer. If you primarily listen to bass-heavy music genres, you might want to look at other options.
Budget-conscious buyers might find the price tag a bit steep. While the Q350s offer great value, they’re still a significant investment. If you’re not ready to spend this much on speakers, there are cheaper alternatives available.
