The KEF Q Concerto Meta pay homage to KEF's classic 1969 model, created for modern audiophiles and home cinema enthusiasts while celebrating a golden age of music. It incorporates engineering advancements like KEF's proprietary Metamaterial Absorption Technology (MAT), which also features in the award-winning KEF R3 Meta and absorbs 99 per cent of unwanted noise from the rear of the tweeter. Their signature Uni-Q driver array, now in its 12th generation also ensures sound quality that's free from distortion and dispersed evenly throughout the room.
To achieve clarity and depth, this speaker features a three-way layout that separates high, mid, and low frequencies, with a crossover that was refined over 1,000 measurements in an anechoic chamber to attain the optimal signal path. The 6.5-inch hybrid aluminium bass driver ensures tight, deep bass, while the magnetic grilles maintain a sleek appearance, protecting the drivers from damage and debris when attached. Available in black, white, and walnut, the KEF Q Concerto Meta is a stylish bookshelf speaker set to complement high-performance audio setups.
