The KEF LSX II is a compact wireless active bookshelf speaker system that works with no separate amplifier or source component. It brings KEF's Uni-Q coaxial driver technology into a fully self-contained wireless format and is the compact model in the brand's wireless active speaker range.

Key specs that matter

KEF quotes a frequency response of 54Hz to 28kHz. The built-in amplification totals 70 + 30W. Each cabinet measures 24.0 x 15.5 x 18.0cm and weighs 7.2kg, which makes it a desk-scale speaker.

Engineering and use context

The system suits a desk or a small room where a separate amplifier and source would not fit. Streaming and wireless inputs connect directly to the speakers' own electronics.

Pairing

No external amplifier or conventional source component is needed, so the whole setup comes down to this pair of speakers.

Alternatives

The LS50 Meta is a larger passive KEF monitor for a system that uses separate amplification.
