The microfiber grille design is a first for KEF and not only looks beautiful but has a negligible effect on performance. The R Series was created to sound its best with or without grilles. This system utilizes internal braces joined by a ‘lossy’ interface and is highly effective at dissipating unwanted vibrations that would otherwise artificially change the sound and music. The new R Series benefits from constrained layer damping. Cabinet BracingĪ solid platform is imperative for great sound. 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 coloring the midrange. The R Series ports have innovative flexible walls. When it comes to generating deep, articulate bass, port design is crucial. KEF has also increased linearity in the magnet system which means more impressive and impactful bass. Combine this stiffness with the cone’s unique geometry and you get near pistonic movement for punch and speed.
KEF Q SERIES 6.5 2 WAY BOOKSHELF SPEAKERS DRIVERS
R Series bass drivers have a two-part structure with a shallow concave aluminum skin atop a paper cone. The result is vastly improved fine detail. The treble escapes naturally because the ‘shadow region’ stops it getting to the cabinet edges. It's a carefully profiled transition that extends the waveguide effect of Uni-Q. The Shadow Flare is an innovative way to cut harmful high frequency cabinet diffraction. The result is purer and more precise sound with stronger imaging. Using simulation and analysis tools KEF’s engineers have been able to dramatically reduce coloration by cutting resonance in the tiny gaps between Uni-Q’s elements.

aluminium Uni-Q, 1in.The evolution of KEF's Uni-Q driver reaches its 12th generation in the R Series. Specificationsĭimension (H x W x D): 358 x 210 x 306 mm, 362 x 210 x 306 mm (with Rubber Feet)ĭrive Units: 6.5in. Q Series bookshelf speakers excel in small spaces. A Uni-Q driver and CFD port mean it punches way above its weight. Midrange clarity is enhanced by driver improvements that mean the DC blocking capacitor to be eliminated from the crossover, allowing a more natural roll-off between drivers. The Q150 proves that the best things come in small packages. Putting the Uni-Q driver in its own sealed cabinet reduces the load on the cone and increases clarity and detail while delivering cleaner bass. With a larger roll surround and new suspension KEF drivers produce cleaner bass at high volumes.Ī new cone structure improves midrange clarity and an enhanced Auxiliary Bass Radiator (ABR) with a new surround and rear suspension enhances bass quality. The Q Series reproduces the nuances of bass instruments with ease. With 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. The result, enhanced by KEF's 'tangerine' waveguide over the tweeter, is a more accurate three-dimensional sound that's dispersed evenly throughout the room. The Uni-Q driver array places the tweeter in the centre of the midrange and bass cone, bringing the acoustic ideal of a single point source closer than ever. With KEF's signature Uni-Q driver array and a Computational Fluid Dynamics (CFD) port, the Q350s deliver detailed natural sound with high clarity and tight bass.įull-length magnetic grilles are optional. If space is limited the Q350 will not limit your musical enjoyment, a Uni-Q driver and clever port design let it open up the sound. KEF Q350 Bookshelf Speaker 2-way bookshelf
