Elevating Home Theatre to Extreme Levels

KEF, a renowned name in audio innovation, takes a giant leap in home entertainment with the introduction of the Ci-R series Ci5160RLM-THX and Ci3160RLM-THX in-wall speakers. These new additions not only promise superior performance but also incorporate cutting-edge technologies from KEF's flagship series, The Reference.

Cutting-Edge MAT Technology Integration

One of the standout features of the Ci-R series is the inclusion of KEF's signature Metamaterial Absorption Technology (MAT). This innovative technology, previously exclusive to The Reference series, absorbs 99% of unwanted noise and reduces distortion, ensuring an unparalleled audio experience.

THX Certified Ultra: Setting the Standard

Both the Ci5160RLM-THX and Ci3160RLM-THX carry the prestigious THX Certified Ultra designation. This certification guarantees meticulous testing in frequency response, output levels, signal-to-noise ratio, and distortion, ensuring these speakers faithfully recreate sound as intended. The THX Ultra Certification indicates optimal performance for rooms up to 3,000 cubic feet, setting a new standard for home theatre audio.

Premium Design with Discreet Aesthetics

Designed to seamlessly blend into any home setting, the speakers feature a sleek 5.5mm thick anodized silver aluminum baffle with color-matched Uni-Q and bass drivers. The magnetic metal grille, paintable to match home interiors, adds to the discreet design. Additionally, a black cloth grille is available for those seeking an alternative aesthetic.

Premium Audio Features Trickle-Down

The Ci-R series inherits key technologies from The Reference series, emphasizing the commitment to delivering uncompromising audio quality. The Ci5160RLM-THX boasts four 6.5-inch hybrid aluminum bass drivers, while the Ci3160RLM-THX features two of the same, complementing the Uni-Q MAT driver.

Anticipating High Praise from CE Critics

As KEF continues to integrate their MAT technology across the lineup, the Ci-R series stands as a testament to the brand's commitment to pushing the boundaries of audio innovation. With THX Certified Ultra performance and a sleek aesthetic, these in-wall speakers are poised to receive high acclaim from CE critics worldwide. Stay tuned for the CE Critic Score, as we eagerly await their verdict on these exceptional additions to the KEF family.
