Suntem mândri să anunțăm că EISA a onorat KEF LSX II cu premiul Wireless Bookshelf Loudspeakers și seria R cu premiul Loudspeaker Serie în categoriile sale pentru cel mai bun produs 2023 - 2024.
Felicitari KEF!
The R Series consists of a trio of floorstanding speakers and a bookshelf speaker to reproduce high-fidelity stereo sound for your favourite music. Discover depth and detail you never knew existed – from the scrape of a plectrum on a guitar string to the emotion and atmosphere of a live performance.
For the greatest movie experience at home, KEF offers both architectural speakers and modular HiFi speakers, such as the R Series, that don’t need custom installation. With three floorstanding speaker models, one bookshelf speaker model and two centre channel speakers to choose from, plus the additional Dolby Atmos surround speaker, different home theatre set-ups can be easily configured with the R Series. Complete the set-up with KEF’s class-leading subwoofers to feel the most immersive cinematic experience, from the deepest rumble to the softest whisper.
Derived from The Reference, Shadow Flare is an innovative way to cut harmful high frequency cabinet diffraction. It's a carefully profiled transition that extends the waveguide effect of Uni-Q. The treble escapes naturally because the ‘shadow region’ stops it getting to the cabinet edges. The result is vastly improved fine detail.
A solid platform is imperative for great sound. The R Series benefits from constrained layer damping, a system that uses internal braces joined by a ‘lossy’ interface. This material converts unwanted vibration into heat, ensuring that the cabinet makes the only sound it needs to: the sound of silence.
R Series bass drivers have a two-part structure with a shallow, concave, aluminium skin atop a paper cone. This stiffness, combined with the cone’s unique geometry, achieves a piston-like movement for punch and speed. The drivers’ magnet system creates a broad and uniform magnetic field which means more impressive and impactful bass.
We only want to hear the drivers, not the resonances or turbulence created by a bass port. The R Series ports have innovative flexible walls. Using computational fluid dynamics, the flare and profile of each port is calculated to delay the onset of turbulence and the flexible port walls prevent resonances from colouring the midrange.
Three carefully selected finishes include sleek Black Gloss, White Gloss and classic Walnut, while special edition finishes include Titanium Gloss and Indigo Gloss for the R7 Meta and R3 Meta respectively.
The R Series has been engineered to perform with or without grilles. The dedicated microfibre grilles are crafted from multiple layers of material and have a suede-like feel. With 1801 precision-cut holes for each driver, performance is ensured even when the drivers are covered. The magnetic fixings provide a secure and precise fit, in keeping with the clean styling of the R Series.
