KEF R11 Meta 2 pcs.

KEF R11 Meta - The complete floorstanding speaker

R11 Meta is the flagship of KEF’s brand-new R Meta series, delivering sublime music reproduction through its four bass drivers and 12th-generation Uni-Q. This is because the bass drivers use an aluminum-paper hybrid, which provides a powerful and refined sound, while the 12th-generation Uni-Q driver and MAT deliver clarity and detail. Shadow Flare technology in particular plays a significant role in R11 Meta’s musical performance, because the profiled transition surface between the tweeter and the midrange directs the sound waves away from the cabinet, making it much easier to hear and pinpoint everything.

Highlights:

• Detailed, precise, and expansive stereo soundstage
• Immersive and incredibly musical
• 12th-gen. Uni-Q delivers a larger soundstage and “sweet spot”
• MAT provides a cleaner and more natural sound
• Optimized tweeter opening for better detail reproduction
• Flexible Decoupling Chassis prevents unwanted vibrations in the cabinet and provides greater clarity
• Hybrid aluminum bass drivers with greater excursion, delivering tight, deep, and controlled bass
• Shadow Flare technology provides a higher level of detail
• Perfect for smaller rooms
• Flexible bass reflex port for better clarity and detail

About the KEF R Meta series

The reason KEF’s speakers have such a natural and neutral sound is their groundbreaking and patented Uni-Q driver, which makes all the sound come from a single point because the tweeter is placed in the acoustic center of the midrange/bass driver. This allows the sound to disperse much more evenly and widely than with conventional speakers, where the sound comes from drivers in different positions. When the sound comes from a single point, KEF avoids the interference problems of conventional speakers, making the sound much cleaner and more natural. When all frequencies reach the ear at the same time, the sound is perceived as far more precise and realistic, which means the instruments sound like real instruments rather than a speaker’s reproduction of them. That is something every speaker strives for, but very few master as well as KEF.

Revolutionary sound absorption with MAT

The biggest news in the R Meta series is the patented MAT. This technology may be the most revolutionary tool in KEF’s acoustic arsenal, taking the performance of the 12th-generation Uni-Q driver to a whole new level in terms of precision and clarity. MAT eliminates distortion and delivers cleaner, more natural acoustic performance. It is the result of joint development with the Acoustic Metamaterials Group. Metamaterials are specially developed structures that use existing materials in such a way that they exhibit new, desirable properties that simply do not exist in naturally occurring substances. MAT's tuned channels absorb 99% of the unwanted sound from the rear of the driver, compared with around 60% absorption in speakers that use other methods.

The result is much more precise imaging and sound. The improved crossover design has fine-tuned the signal path and brought about significantly improved transparency. The optimized cabinet design means even better acoustic performance. The result is optimal bass response and even better transient reproduction.

Shadow Flare for better clarity

In the latest version of the R Meta series, KEF has also used an innovative solution to remove the harmful diffraction and turbulence that “muddy” the soundstage. They have done this by using ‘Shadow Flare’ technology, taken directly from their reference series, and the result is much better reproduction of the finer details. With KEF’s Meta series, you will therefore experience getting much closer to the instruments, because you can hear and visualize all the fine details, especially from string instruments and percussion.

However, it is not only at high frequencies that the R Meta series shines, because the bass driver is an advanced aluminum-paper hybrid that ensures a perfect combination of stiffness and lightness, allowing the bass to reproduce the very deepest tones with the greatest speed.

Flexible port for cleaner bass

To enable the R Meta series to deliver truly deep and articulate bass, KEF has designed a bass reflex port that delays turbulence and prevents resonances from coloring the midrange. In addition, they have designed a cabinet that uses both hard and soft components to eliminate the unwanted vibrations that would otherwise alter the sound and the music. KEF has also chosen a much slimmer design than its predecessors, which not only makes the speaker look better but also sound better. At KEF, everything is about improving the sound, and the closer the drivers are to the edge of the baffle, the less diffraction occurs. The result is that the sound does not become “muddy” but instead sounds crystal clear.

Critical damping for better performance

Powerful drivers can easily cause the cabinet itself to make noise—noise that was never part of the recording to begin with. Together with the internal bracing, KEF's Constrained Layer Damping is a sophisticated reinforcement system that ensures the cabinet remains completely inert. This has been achieved by connecting the bracing to the drivers and cabinet with a lossy interface. This material converts vibrations into heat, ensuring that the cabinet makes the only sound it needs to make - the sound of silence.
