3-way bookshelf speaker
The Q Concerto Meta HiFi speaker is the largest in our Q Series bookshelf speaker collection. Paying tribute to the original 1969 Concerto, which was our first 3-way standmount speaker, this modernised version delivers professional high-end audio quality. Thanks to its 3-way design and Metamaterial Absorption Technology (MAT™), this wired speaker is sure to deliver high-fidelity performance.
Metamaterial Absorption Technology
Revolutionary technology that can absorb 99% of the unwanted noise from the rear of the driver for pure and natural sound.
12th Generation Uni-Q®
Acts as a single point source to disperse sound more evenly for an immersive and cohesive soundstage with better clarity.
3-way Speaker Design
Ensures precise separation of high, mid, and low frequencies for exceptional detail and clarity, bringing music and movies to life.
Deep and Clean Bass
Hybrid aluminium bass drivers with greater driver excursion for tight, deep, controlled bass.
Home Theatre made Versatile
Mix and match with other Q Series speakers and KEF subwoofers for a versatile home theatre experience that transports you to the heart of the action.
Refined Crossover
Developed using over 1000 measurements in an anechoic chamber, ensures precise signal path for best possible performance.
Magnetic Grilles
Complementary colour-matched grilles offer the perfect balance between driver protection and aesthetics.
