Product details

KEF’s R3 Meta is a three-way bookshelf speaker that brings the R Meta range’s acoustic technology to a compact standmount format. A 12th-generation Uni-Q array places a 25 mm tweeter at the centre of a 125 mm midrange cone, supported by 1 × 165 mm (6.5 in) hybrid aluminium bass driver.

Uni-Q with Metamaterial Absorption Technology

MAT absorbs unwanted sound from behind the tweeter. Shadow Flare reduces cabinet-edge diffraction, while a flexible decoupling chassis and constrained-layer damping limit vibration and colouration.

Controlled bass and system matching

Hybrid aluminium cone construction combines an aluminium skin with a paper cone for stiffness and controlled motion. Flexible rear ports reduce resonance and turbulence. KEF recommends a 15–180 W amplifier; nominal impedance is 4 Ω.

Supplied as a stereo pair with magnetic microfibre grilles and rubber feet and port bungs. Matching S3 stands are optional. Available in Black Gloss, White Gloss and Walnut; Indigo Gloss Special Edition is also offered.
