Floorstanding loudspeakers — KEF R11 Meta

The KEF R11 Meta is the largest floorstanding speaker in the R Series. The R Series sits above the more affordable Q Series in KEF's line-up and uses more advanced cabinets and drivers, while the considerably more expensive Reference and Blade ranges sit above it. The R11 Meta is the fullest floorstanding form of KEF's Meta engineering at this level.

Key specs that matter

The R11 Meta covers 46Hz to 28kHz. Sensitivity is 90dB and nominal impedance is a low 4 ohms. KEF recommends amplifiers from 15 to 300W, a wide range that covers both modest and far more powerful designs. The speaker measures 124.9 x 20 x 38.4cm and weighs 36.5kg, which makes it a tall and substantial tower.

Engineering and use context

KEF fits the tweeter with its Metamaterial Absorption Technology. Placed behind the dome, it is designed to reduce interference from the rear wave compared with a conventional tweeter.

Pairing

Because of the low nominal impedance, the amplifier should be specified for 4-ohm operation.

Alternatives

The KEF R7 Meta sits below this model in the R Series and suits a smaller room or a more modest budget.
