The ProAc Tablette range has been in development for almost 40 years. The first speakers in the range were originally released in 1979, and now these 10th generation ProAc Tablette 10 Signature loudspeakers are about to up the game even further. With an all new design, these speakers have been constructed using a thin walled, heavy damped infinite baffle enclosure – the same baffle that was previously used in the BBC LS3/5a. This design method allows the Tablette 10 Signatures to boast an added flexibility in its positioning options, meaning you can now place these loudspeakers directly against the wall – a method of positioning that would not be possible with ported enclosures. Each of the Tablette 10 Signature Loudspeakers includes a new, cutting edge drive unit in order to offer a much better sound reproduction when compared to previous models, and the bass driver uses a Paganni Mika cone. This Paginna Mika cone is constructed using reed leaves mixed with Mika and then coated with an acoustic dope. A specially designed crossover can be found in these loudspeakers, designed for use within a sealed enclosure, and including a network that shapes the response in order to deliver a richer bass and a more transparent midrange. The tweeter found within the speakers is ProAc’s popular 1 inch silk dome. More flexibility in positioning options 10th generation Tablette speaker Paganni Mika bass driver cone New, cutting edge drive units Specially designed crossover Please note that the Tablette 10 Signatures do not come with the stands pictured ProAc Tablette 10 Signature Speakers follow the hugely successful introduction of the Tablette 10 in 2017, sharing many of its proven components. Signature Model This new Signature model uses the same cabinet and ProAc soft dome tweeter utilised in the Tablette 10 but the performance if further enhanced through the addition of a new bass driver made of the same Paginna Mika cone material but with a high-quality copper magnet system and phase plug. Silk Dome Tweeter The tweeter used in the Signature model is ProAc's highly renowned 1" silk dome model which is also used in many of ProAc's other models. During the design, several speakers were used as comparison those being the LS3/5a, ProAc D2, Spender BC1 and Quad Esl 57. Rich and Smooth When designing the Tablette 10, the legendary LS35A design was used for comparison and the resulting ProAc speaker is even less coloured. Tablette 10 Signature not only improves on this but the midrange and bass qualities benefit from a finely tuned crossover designed after many months of listening. This gives it a smoother and more detailed presentation over the standard model which can be clearly heard on various types of music, whether vocal or instrumental. A thin-walled heavy damped infinite baffle enclosure means the Tablette 10 Signature can be positioned with its rear baffle close to a wall on a shelf but will give its best performance when stand-mounted. Cabinet Design Tablette 10 Signature is available in ProAc's 5 standard wood finishes; Black Ash, Cherry, Mahogany, Maple and Silk White along with the Rosewood and Ebony premium finishes. On top of high quality sound, you can be assured you'll get a visually appealing wood design that fits in well with your personal taste or home decor.

An icon born from The Reference Derived from The Reference, the R6 Meta hosts a suite of class-leading technological innovations to deliver exceptional acoustic performance. Decades of experience combine to create an exciting sound which sets the benchmark for future loudspeaker design. Whether you're looking for a home Hi-Fi solution or multi-channel home theatre, the R-Series reveals levels of detail that must be heard to be believed. etamaterial Absorption Technology A complex maze-like structure, each channel efficiently absorbs a specific frequency and when each channel is combined an acoustic 'black hole' is created, absorbing up to 99 percent of unwanted resonances that occur in the rear of the tweeter. You can expect to hear a more natural, pure acoustic tone. The signature KEF sound A refined 12th-generation Uni-Q driver has been implemented to work along with the MAT technology for a design that's specific to the speaker. This is combined with a re-engineered tweeter gap damper which places two rings of porous material to tame imperfections and resonances, greatly improving detail and clarity. Shadow Flare for improved clarity Designed to allow the 12th-generation Uni-Q drivers to work to their optimum, Shadow Flare is a precision-designed surface which extends the waveguide. This means it no longer has line of sight to the cabinet edges, creating a 'shadow region' where diffraction is highest. The result is an incredibly clear high-frequency sweet spot for more detailed listening. Powerful, deep lows Built with a two-part structure, the R6 Meta delivers the most articulate and powerful bass frequencies. A shallow concave aluminium skin is mounted on top of a paper cone with a unique geometry to effectively reduce resonances for a clean, pristine and deep low-end response. A uniform magnetic field is created with the onboard driver system to reduce harmonic distortion. Flexible Decoupled Chassis First used on the Blade and The Reference loudspeakers, the chassis design is employed to ensure the Uni-Q drivers dramatically reduce colouration of the sound by eliminating cabinet vibrations. By decoupling the midrange driver from the chassis, the vibrations are dissipated and transferred into heat, effectively eliminating any unwanted sound. Get the ultimate sonic experience at home With identical Uni-Q driver arrays deployed on the centre speakers and all other R-Series speakers, the R6 Meta is perfectly capable of being used in an LCR configuration. This configuration creates a consistent sound character, maintaining focus on the audio reproduction and not the equipment, making it perfect for a wide range of home-listening environments. Custom-design microfibre grille Made from multiple pieces layered together, this precision-cut grille features 1,801 cut holes to provide a stylish aesthetic to your speakers, all without interfering with the sonic quality. Perfect for matching the look of your speakers to your environment, they also feature burnished edges for a suede-like feel.

40 years of excellence Innovation. 801 D4 is defined by it. In each of its incarnations over the decades, 801 has always been the most advanced loudspeaker that we know to make at that particular point in time, a showcase of all our newest technologies and most original thinking. Small wonder it has become an icon. The ultimate Matrix™ Matrix bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage. The Matrix assembly in 801 D4 is our best yet, upgraded with extensive aluminium bracing to reinforce key stress points. Turbine™ Head The all-aluminium Turbine Head houses our Continuum™ midrange cone in a stiff and critically damped enclosure to eliminate unwanted resonances. At the same time, it’s decoupled from both the bass enclosure and the tweeter body. The result? The most realistic midrange sound yet. Biomimetic Suspension Sometimes, making a big difference takes unconventional thinking. Our new Biomimetic Suspension revolutionises midrange performance by greatly reducing the unwanted air pressure and coloration that a traditional fabric spider can generate. The result? Midrange transparency you wouldn’t believe. The science of sound Innovation is at the heart of everything we do. We question, we examine, we understand and then we evolve. We use computer modelling to explore and reimagine every aspect of loudspeaker design. Learn more about all the technologies that combine to make 800 Series Diamond so special here.

KC62 slips effortlessly 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; in free space, next to the wall, in a corner, nestled within a cabinet or using the dedicated apartment mode. Design meets substance The KC62 is not just designed to work sonically within your home, but aesthetically as well. Crafted from extruded aluminium, the curved cabinet perfectly blends form and function, providing strength and beauty. Whilst diminutive enough to blend into the décor, the Carbon Black and Mineral White finishes also make KC62 an exceptionally attractive statement. Uni-Core™ Technology At the heart of KC62 is KEF’s innovative, patent-pending Uni-Core driver technology. A completely new take on traditional force cancelling arrangements, the Uni-Core design delivers ultra-compact size and big performance. In order to simultaneously deliver unprecedented performance and the benefits of force cancelling from a compact size, Uni-Core combines both drivers into a single magnet system, with the voice coils concentrically arranged. This allows the cabinet size to be reduced by over a third, while equalling or exceeding the driver excursion of a much larger subwoofer, unlocking more output and depth from less space. P-Flex Surround (aka Origami Surround) The second of the three new technologies in KC62 is a brand-new design of driver surround. The new, patent-pending P-Flex surround is engineered to better resist the acoustic pressure in the cabinet without limiting sensitivity in the same way traditional surround designs do. To achieve this, it uses a unique pleated design inspired by Origami, the Japanese art of paper folding, which resists the internal air pressure without adding excessive mass, allowing the driver to move precisely as required by the audio signal. The result is deeper bass extension and a more accurate and detailed bass reproduction.

The LS60's sound profile is smooth, consistent, and extremely natural, delivering an incredibly accurate and immersive listening experience. Taking advantage of KEF's innovative technologies, the Single Apparent Source design utilises precise driver calibration to ensure that the entire frequency spectrum appears to radiate from a single point. Taken from their flagship Blade speaker, this feature gives these wireless floorstanding speakers highly accurate imaging and accurate sound across larger space. The LS60's drivers are built with KEF's Uni-Q® driver array, which places its vented tweeter in the acoustic centre of the cone. This combined with their Uni-Core™ woofer design which improves force cancelling drivers to output deeper, accurate bass from smaller cabinets makes these speakers sound truly excellent at all times. This one-two punch of innovative driver design ensures that the LS60's sound is consistent no matter where you are in the room. No more hunting for the best position, your entire space has now become one large sweet spot. The final unique characteristic of the LS60's sound is its Metamaterial Absorption Technology (MAT™). MAT is a complex, winding structure that eliminates unwanted sound from the rear of the speaker drivers, delivering a pure and realistic sound that you'll get lost in instantaneously. Loading a single speaker with all of this staggering technology makes the LS60's some of the most natural sounding floorstanding speakers available. Featuring not just one, but four unique technical innovations in a pair of speakers, the LS60 deliver acoustic excellence for any occasion. Celebrating 60 Years of Innovation LS60 Wireless combines all of KEF's core technology to provide one of the most technologically advanced wireless floorstanding speakers. Designed in Collaboration with Michael Young Minimalistic, and futuristic, the LS60's physical design reflects what KEF are aiming to achieve sonically. The LS60 look and feel natural, and sleek. Single Apparent Source Technology Utilising precise calibration of their drivers, the LS60 gives exceedingly coherent sound that appears to come from a single point, delivering detailed stereo information and accurate sound across a larger space. Uni-Q Driver Design By placing the tweeter accurately at the acoustic centre of the bass/midrange drivers, both units act together as a single point source. This makes for a more even sound distribution, eliminating the need for sweet spots. The LS60 sounds its best absolutely everywhere. Uni-Core Speaker Cones KEF's engineers have iterated on typical force cancelling speaker cones by combining the traditional back-to-back drivers into a single motor system. The overlapping voice coils deliver improved driver excursion, giving low frequencies more depth and output in smaller cabinets. Metamaterial Absorption Technology MAT™ is an advanced, maze-like structure that eliminates unwanted sound from the rear of the driver, giving pure, realistic sound. Designed in collaboration with the Acoustic Metamaterials Group, this feature revolutionises loudspeaker design. Music Integrity Engine The Music Integrity Engine, having been the heart of KEF's previous LS50 Wireless II is a collection of bespoke Digital Signal Processing algorithms. These algorithms are optimised for the Uni-Q drivers, making them deliver a perfectly timed performance, improving imaging and tightening sound for snappy, clear transients. Advanced Amplification The LS60's built-in amplifiers deliver a total of 1400 W of amplification. Class A/B tweeter amplification provides smooth, nuanced treble that fits the LS60's natural, realistic sound. Then, dedicated Class D amplification powering the mid and bass drivers assure powerful, but controlled and articulate low-frequencies. Comprehensive Connectivity The LS60 supports audio streaming from a wide variety of formats. All major music streaming services, a wide range of supported audio formats, and wireless streaming via Chromecast, Bluetooth, or Roon are all options.
