Bookshelf Speakers — KEF R3 Meta

The KEF R3 Meta is a bookshelf speaker from the R series, based on the brand's Metamaterial Absorption Technology (MAT) tweeter loading. It sits alongside the Q Concerto Meta among KEF's bookshelf models and belongs to the numbered R series, which also includes larger floorstanders.

Key specs that matter

The R3 Meta covers 58Hz to 28kHz and has a sensitivity of 87dB with a nominal 4 ohm impedance. KEF recommends amplifiers of 15 to 180W. The cabinet measures 42.2 x 20.0 x 33.6cm and weighs 12.4kg, a substantial size for a stand-mount speaker.

Engineering and use context

MAT loading is designed to absorb the rear wave of the tweeter. KEF first introduced it in the LS50 Meta, and the technology has since spread into the wider R-series range.

Pairing

A mid-power integrated amplifier is enough here, as the 4 ohm load and moderate sensitivity do not ask for unusual current.

Alternatives

The LS50 Meta, where MAT first appeared, is a more compact KEF stand-mount in a different cabinet configuration.
