3-way bookshelf speakers that produce pure, crystal-clear sound
The Q Concerto Meta Hifi speakers are the largest in KEF's Q Series bookshelf speaker collection. Paying homage to the original 1969 Concerto, KEF's first 3-way floorstanding loudspeakers, these upgraded versions deliver high-end professional audio quality. Thanks to their three-way design and Metamaterial Absorption Technology (MAT), these wired speakers deliver high fidelity performance.
Unique construction
The 12th generation Uni-Q incorporates drivers with MAT technology to deliver an even more impressive acoustic experience. Metamaterial Absorption Technology (MAT) is a labyrinthine structure that effectively absorbs 99% of unwanted sound coming from behind the tweeter. As a result, there is no distortion of the sound, for a natural, pure listening experience.
Inside, the KEF Q Concerto Meta speakers feature the famous Uni-Q coaxial driver, which now benefits from MAT technology to optimise fine detail. The woofer, meanwhile, is a 16.5cm model that performs as it should to bring you first-rate sound.
