Sit anywhere” Uni-Q Sound

At the heart of the evolved Q Series is the Uni-Q driver array. KEF’s signature innovation places the tweeter in the acoustic center of the midrange cone, bringing the acoustic ideal of a single point source closer than ever to realisation. The result is a more detailed, more accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with a conventional speaker. Uni-Q’s ultra-wide dispersion is further enhanced by KEF’s ‘tangerine’ waveguide over the tweeter dome.

Uni-Q Sound Taken To The Next Level:

The 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 response.

Redesigned Bass Drivers:

Low-frequency (LF) drivers now have a larger roll surround, along with a new spider suspension to produce cleaner bass at high volumes. A new cone structure improves midrange clarity, and an enhanced Auxiliary Bass Radiators (ABRs) with a new surround and rear suspension delivers better controlled and more impressive bass.

New Cabinet Design:

In our newest line of Q Series Floorstanders the Uni-Q driver has been placed in sealed box within the cabinet. The closed box midrange cabinet design reduces the load on the Uni-Q midrange cone, increasing clarity and detail while delivering cleaner, punchier bass. Midrange clarity is enhanced again through improvements to the mid-bass driver that allowed the DC blocking capacitor to be eliminated. Its removal also created a more natural bass roll-off between the drivers.

Description:

Uni-Q Driver Array:

Developed by KEF in 1988, the Uni-Q driver array acts as a single point source, providing pristine sound across a wider area. The R Series benefits from a new incarnation of this driver array, with advantages over its predecessors that include a new midrange motor system that drastically reduces distortion.

Air moving across the minute gaps between Uni-Q’s separate elements creates tiny resonances, but KEF engineers have reduced the impact of these necessary gaps by opening a cavity behind the drivers and adding resonance-absorbing damping material for more precise, purer treble.

Shadow Flare:

Derived from the Reference Series, the Shadow Flare reduces harmful cabinet diffraction and allows the Uni-Q to work at its highest level.

More than just a trim ring, Shadow flare is a precision-designed surface that extends the waveguide effect of Uni-Q. The tweeter no longer has line of sight of the cabinet edges, creating a ‘shadow region’ at the points where the potential for diffraction is highest, minimising the acoustic impact to negligible levels.

The result is improved clarity, particularly when it comes to the subtle nuances of plucked strings and percussive sounds.

Low Frequency Drivers:

The R Series’ dedicated low-frequency drivers have a two-part structure, where a shallow concave aluminium skin sits atop a paper cone. This adds stiffness, while the cone’s unique geometry reduces resonances and delivers the pistonic movement that makes these drivers time so well.

The new drivers also have a completely redesigned magnet system that creates a more even magnetic field, and a design of spider that reduces harmonic distortion for a cleaner, more precise sound.

Cabinet Bracing:

The R Series benefits from Constrained Layer Damping bracing originally developed for the multiple award-winning LS50, and a new internal bracing layout. This combination brings the R Series closer to the internal structure of the Reference Series, and helps it deliver music as it is supposed to sound, without any unwanted extras.

Flexible Port Technology:

KEF engineers computer-modeled the ideal crossover networks before exhaustively auditioning every high grade component, individually and together, to select those with the lowest distortion and the smoothest response. Perfectionism takes time, but the difference is plain to hear. Nothing is overlooked – Reference crossovers are even mounted on separate boards and decoupled from the cabinet walls to minimize vibration and crosstalk.

KEF REFERENCE 5 exemplifies the passion for innovation that underpins THE REFERENCE design philosophy. For music or film, it reveals subtleties you’d never noticed while gripping your emotions with the full power of the performance.

Uni-Q Driver Array
At the heart of The Reference is a stunning new iteration of KEF’s landmark innovation: the Uni-Q point source MF/HF driver array. With a state-of-the-art 25mm (1in.) vented aluminium dome tweeter at the exact acoustic center of a highly sophisticated 125mm (5in.) mid range driver, both act as a single source that floods the listening space evenly with a flawless natural sound field, no matter where you sit. Capturing all the nuances of the human voice, whether whispered, spoken or sung, it sounds as if the person were right there with you in the room. All the jaw-dropping performance and innovative engineering pioneered for the critically acclaimed LS50 studio monitor, and then some. Reference 5 pairs KEF’s latest 125mm (5 inch) MF/HF Uni-Q driver array with four sensational new 165mm (6.5 inch) alloy cone bass driver to create a compellingly realistic and completely immersive sound stage. The Reference 5’s Uni-Q cast an inherently wide, even dispersion that also also makes it a tremendous rear channel speaker in a home theater system that effortlessly reveals all the subtleties encoded in modern soundtracks.

Bass Driver
Clean, rich and articulate bass grounds your enjoyment of stereo or multi-channel sound, and like everything else about The KEF Reference 5 , KEF’s new 165mm (6.5 inch) LF driver is in a class apart. With a massive vented magnet assembly and a large aluminium wire voice coil driving an exceptionally light, stiff and strong alloy cone, the dynamics and power handling are superb. Played loud or soft, in delicate passages or for full-on bass effects, the combination of advanced materials and clever engineering delivers deeply rewarding lows that blend seamlessly with Uni-Q’s immaculate mid range and treble response. The Reference 5 features four of these immensely powerful bass drivers.

Cabinet Design
The Reference drivers are set in a smooth, strikingly distinctive front baffle engineered to eliminate response anomalies caused by diffraction. Made from an exceptionally strong laminated aluminium/resin composite and secured via high-loss pads and high tensile bolts, it adds tremendous rigidity to the inert cabinet. Finished by hand in pair-matched wood veneers to complement the composite front baffle, the shape and bracing geometry of the cabinets are computer-optimized to minimize secondary radiation from the cabinet walls and distortion from standing waves. With constrained layer damping to absorb residual vibrations, they’re engineered to eliminate any panel resonance, stray reflections or box coloration effects that would compromise the purity of the sound.

Flexible Port Technology
The flexible port technology pioneered for the multi-award winning LS50 is used to reduce mid range port resonance, with the flare and profile of each port calculated by computational fluid dynamics to avoid turbulent air noise that might color the sound.

The Reference has innovative adjustable ports for fine-tuning the bass output to your personal taste and the room characteristics providing the ultimate flexibility for any room.

Description:

For a lifetime of listening pleasure

Where space is at a premium KEF BLADE TWO offers all of the acoustic prowess and iconic design of KEF BLADE TWO on a slightly smaller scale.

KEF BLADE TWO. Same DNA. Same striking aesthetic. Same advanced driver technology and unique single apparent source configuration. And above all, the same open, phenomenally realistic sound.

 Single apparent source
Like listening to one voice rather than many, sound from a single source is inherently clearer. Not only are the acoustic centres of the HF and MF drivers in the Blade & Blade Two Uni-Q array coincident, but the four LF drivers, (225mm/9-in. for Blade, or 165mm/6.5-in. for Blade Two) are mounted symmetrically equidistant from it so that their acoustic centres occupy exactly the same point in space.

This single apparent source configuration is what makes the Blade & Blade Two so gratifyingly coherent across the frequency range, with noticeably more precise imaging than is possible from any conventional speaker.

What you hear sounds as if it’s being performed live right in front of you.

Discrete bass chambers
The twinned pairs of bass drivers are mounted in discrete chambers separated by an internal partition. By increasing the frequency of any internal standing waves to way beyond the crossover point, this reduces the need for damping material (which can otherwise impair bass quality). Nothing has been overlooked in the quest for the ultimate clarity, right across the frequency range.

Force cancelling
To avoid dissipating the energy of such potent bass drivers in exciting the cabinet (and thereby generating resonance, especially at high volume), the large kinetic forces involved are cancelled out by mounting the LF drivers rigidly together, back-to-back.

By minimising cabinet colouration, this highly effective configuration partly accounts for the Blade & Blade Two’s natural-sounding and engagingly musical performance.

Attention to detail
With speakers as ambitious as the Blade & Blade Two, short cuts are out of the question. Everything has to be as right as it can possibly be.

Terminals & terminal links
Two pairs of the finest audiophile quality WBT connectors allow bi-wiring or bi-amping to optimise the retrieval of low level detail in the music.

Low order crossovers
The simple low order crossovers specified for both Blade & Blade Two employ the best components available, carefully selected by a rigorous auditioning process so that every part of the signal path is fine-tuned for maximum clarity.

Hard wiring
The patented screw-in linking plugs are to full audiophile specification (as well as simplifying set-up by eliminating fiddly wiring links). All the crossover components are individually wired by hand rather than mounted on a conventional printed circuit board. As well as being more environment-friendly, this optimises both reliability and sound quality by assuring the cleanest possible signal transmission.
