The R series is designed to be acoustically exceptional. Every element of the design has been precisely tuned to provide more detail and deeper insight into the sound. Developed for KEF's top models, many of the latest technologies have been incorporated into the new generation of the R Series Meta.

The R series offers exceptional acoustic performance that becomes more accessible, with the innovative Metamaterial Absorption Technology (MAT) that reveals a new sense of music.

• MAT Technology: A revolutionary construction that absorbs 99% of unwanted sound from the back of the driver.
• Uni-Q Technology: The tweeter is placed precisely at the acoustic center of the bass/midrange cone, creating a coaxial sound emission system.
• High Vibration Damping: The system uses internal supports that convert unwanted vibrations into heat.
• True Bass Clarity: The bass drivers have a two-part structure with an aluminum surface and a paper cone, ensuring intense and fast response.
• Special Microfiber Grilles: Designed to perform equally well with or without grilles.

The speakers are sold without stands.
