Expert Audio Engineering Commentary

Tonal Profile

Uni-Q 12th Generation driver with Metamaterial Absorption Technology (MAT). Exceptional point-source imaging.

Amplification Warning

Underpowered budget receivers rated only for 8 Ohms will run excessively hot, clip during bass transients, or sound thin and compressed on LS50 Meta.

Acoustic Characteristics

Combines low sensitivity (85 dB at 2.83 V / 1 m) with a published impedance minimum of 3.5 ohms against an 8-ohm nominal. KEF recommends 40-100 W of amplifier power; the dip is what decides whether an amplifier stays comfortable, not the nominal figure.
