KEF Launches the KC62 Subwoofer with Uni-Core Tech

KEF has once again developed three innovative technologies that successfully prioritise design and sound in equal measure. Deep and powerful bass is no longer solely the domain of big-shouldered, massive subwoofers. Through exceptional engineering and creativity, KEF engineers have developed a brand new approach and new technologies to accurately reproduce the original recording, bringing all the splendour, impact and emotion from music and films.
Thanks to these innovative KEF technologies, the KEF KC62 Uni-Core Force-Cancelling subwoofer has changed our expectations of subwoofer design forever. The cabinet is incredibly sufficient at withstanding a range of bass production, from deep thunder to quick and sharp agile bass without moving.

With a new compact and sleek design, the KC62 subwoofer also delivers unprecedented depth and breath-taking accuracy in equal measure. This is a result of the patent-pending, ground-breaking Uni-Core technology, which is an entirely new take on subwoofer engineering. KEF continues to revolutionise traditional expectations of what a subwoofer can achieve in particular the KC62’s force cancelling abilities. The Uni-Core design delivers ultra-compact size and big performance, which sits at the heart of the innovative KC62.

Uni-Core
To simultaneously deliver unprecedented performance and the benefits of force cancelation Uni-Core combines the two through a single motor system with the voice coils concentrically arranged. This allows the cabinet size to be reduced by over a third whilst equalling or exceeding the driver excursion of a much larger subwoofer; unlocking more output and depth from less space. Uni-Core enables the subwoofer to deliver high performance and powerful, dynamic, accurate sound in an ultra-compact size.
The KC62 has proven its versatility with accurate, deep bass, speed and power. Along with the space-saving Uni-Core, a second and third technology allow the subwoofer to excel in the aforementioned ways.
P-Flex Surround
The P-Flex Surround is a brand-new patent-pending driver surround. It resists the acoustic pressure inside the cabinet without limiting sensitivity in the same way traditional surround designs do. To achieve this, it is uniquely pleated in such a way that is inspired by the Japanese art of paper-folding earning itself the nickname Origami Surround. It is this meticulous design that resists the internal air pressure without adding excessive mass, allowing the driver to move as required by the audio signal. The result is a deeper bass extension and a more accurate, detailed bass reproduction and distortion reduction.

Smart Distortion Control Technology
This patent-pending, sensorless, motional feedback system helps correct even the slightest abnormalities that may occur. It does this by measuring the current in the voice coil and detecting and correcting any non-linear distortions, which delivers more accurate, less coloured bass performance. The new approach reduces the interaction between signal, amplifier and driver, which dramatically decreases the potential for distortion.
The KC62‘s performance is finetuned further still by a bespoke selection of in-house designed DSP (Digital Signal Processing) algorithms in the form of KEF’s Music Integrity Engine. Algorithms including iBX (Intelligent Bass Extension) and SmartLimiter, which continually analyses the signal to prevent clipping, work together to ensure the perfect relationship between all components.

The final piece of the performance puzzle is amplification, which the KC62 has in abundance. The twin drivers are powered by 1,000W RMS (2 x 500W) of specially designed Class D amplification, providing exceptional levels of control and the ability to deliver sudden bursts of power when required, for example when enjoying your favourite high-octane action sequence. Turn up the power; listen and believe.
The KC62 is also incredibly versatile, with a collection of connection options that allow it to work with almost any audio system. The line output with HPF allows for exceptional finetuned integration, while KEF SmartConnect eliminates any connection issues. The KC62 is also compatible with the KW1 adaptor kit for wireless compatibility with the minimum of fuss.
Intricate design does not require a complicated setup. The KC62 can sonically integrate into any environment or listening room thanks to the five pre-set Room Placement Equalisation feature, which ensures you get the same performance from KC62 no matter where you decide to place it. Achieve seamless integration in free space, next to the wall, in a corner, nestled within a cabinet, or using the dedicated apartment mode.
The design allows the KC62 to work sonically within your home. It is also an aesthetically pleasing addition to your space. The KC62 is crafted from extruded aluminium, creating a curved cabinet which perfectly blends form and function, strength and beauty. Whilst diminutive enough to blend into the décor, the Carbon Black and Mineral White finishes also make KC62 a beautiful statement.
The pricing of the device will be AED 5999 including VAT and it will be available end of March 2021.

TOZO NC9 Earbuds Review: Budget ANC Earbuds With a Battery Display

The TOZO NC9 is a pair of true wireless earbuds featuring Active Noise Cancellation (ANC), a sleek design, and solid audio performance at a competitive price. TOZO has built a reputation for delivering affordable yet capable audio gear, but does the NC9 stand out in a market flooded with budget ANC options? Let’s take a closer look.
Design and Build Quality
The TOZO NC9 adopts a minimalist in-ear design. The earbuds have a matte finish that resists fingerprints and smudges, maintaining a clean look even with frequent use. Each earbud weighs just 5 grams, making them comfortable for extended wear, and they come with three pairs of silicone ear tip sizes to ensure a secure fit.
The charging case is compact and pocket-friendly, featuring a smooth, pebble-like shape with a satisfying magnetic snap closure. While the build is primarily plastic—expected at this price—the overall feel is sturdy and well-constructed.
One of the standout features of the charging case is that it has an LED display on the front that shows the battery level of the case and the earbuds. Another notable highlight is the IPX6 water resistance, which makes the NC9 resistant to sweat and light rain, adding durability for workouts and outdoor use.
Technical Specifications
The TOZO NC9 is equipped with Bluetooth 5.3, ensuring a stable connection with minimal latency. It features Hybrid Active Noise Cancellation, capable of reducing ambient noise by up to 35dB, and is powered by 9mm dynamic drivers for audio output.
While the earbuds support SBC and AAC codecs, the absence of aptX or LDAC means audiophiles may miss higher-resolution streaming. Battery life is solid, offering up to 6 hours of playback with ANC enabled (24 hours with the case) and 9 hours without ANC (40 hours with the case). Charging is handled via USB-C, with a full recharge taking about two hours, and the case also supports wireless charging for added convenience. Touch controls are fully customizable through the TOZO companion app, allowing users to tailor gestures for playback, calls, and ANC modes.
Audio Performance
The 9mm dynamic drivers deliver a V-shaped sound signature, emphasizing bass and treble while slightly recessing the mids. This tuning makes the NC9 particularly well-suited for bass-heavy genres such as EDM, hip-hop, and pop, though vocals and acoustic instruments may not be as pronounced as on more neutral-sounding earbuds.
The bass response is punchy and deep without becoming muddy, while the treble remains crisp, though it can get slightly harsh at higher volumes. The midrange is clear but not as forward as some listeners might prefer, which may affect the naturalness of voices and certain instruments.
When it comes to Active Noise Cancellation, the NC9 performs admirably for its price, effectively dampening low-frequency noises such as airplane engines, traffic, and air conditioning. However, higher-pitched sounds (such as chatter or barking dogs) are less effectively blocked. The Transparency Mode works well, allowing external sounds to pass through clearly when needed.
Battery Indicator Screen
One of the standout features of the NC9, as mentioned before, is its LED battery percentage display on the charging case. Unlike many budget earbuds that rely on vague LED indicators, this small screen provides an exact remaining charge percentage, eliminating guesswork and ensuring you always know how much battery is left.
Additional Features
The TOZO companion app enhances the user experience by allowing customization of the EQ, touch controls, and ANC settings. A low-latency mode helps reduce audio lag for gaming and video watching, though some minor delay may still be noticeable.
The earbuds also support multi-point connectivity, enabling simultaneous pairing with two devices—a useful feature for switching between a phone and laptop. Pairing is quick and hassle-free, with most devices recognizing the NC9 instantly.
Verdict
The TOZO NC9 delivers very good ANC performance for its price, along with a comfortable, secure fit and IPX6 water resistance. The battery life is solid, and the inclusion of wireless charging and a battery percentage display adds convenience rarely seen in budget earbuds. Sound quality is energetic and bass-forward, making these a great choice for casual listeners and commuters.
While the ANC is effective for low-frequency noise, it struggles with higher-pitched sounds. The lack of aptX or LDAC support may disappoint those seeking higher-resolution audio, and the V-shaped tuning might not suit listeners who prefer balanced mids.
If you’re looking for affordable ANC earbuds with good battery life, wireless charging, and a useful battery display, the TOZO NC9 is an excellent choice. However, if you prioritize audiophile-grade sound or stronger ANC for voices and sharp noises, you may want to consider higher-end models.
Pros:
✅ Strong ANC for the price
✅ Good battery life with wireless charging
✅ Clear battery percentage display
✅ Comfortable, secure fit with IPX6 rating
✅ Customizable via TOZO app
Cons:
❌ No aptX/LDAC for high-res audio
❌ Mid-range clarity could be better
❌ ANC struggles with high-frequency noise
Price: AED 150
