The R series is designed for exceptional acoustic performance. Every element of the design has been precisely tuned to provide more detail in the sound, recreating the sense of enthusiastic listening to an original music performance.

Developed for KEF's top models "The Reference," many of the latest technologies have been incorporated into the new generation of the R Meta series.

With the innovative Metamaterial Absorption Technology (MAT), the R series reveals a new sense of music worth enjoying.

• MAT Technology: It is a revolutionary tool in KEF's acoustic tools, with a labyrinth-like structure, absorbing 99% of unwanted sound.
• Uni-Q Technology: Places the tweeter right at the center of the bass cone, creating a coaxial sound emission system.
• High Vibration Damping: Significant base construction using material that converts unwanted vibrations into heat.
• True Bass Clarity: The bass drivers feature a unique geometry and two-part structure for speed and intensity in sound.
• Special Microfiber Grilles: Made from multiple layers, ensuring good performance even when covered.

The speakers are sold without the pictured stands.
