Bookshelf Speakers — KEF LSX II

The LSX II is a compact wireless active bookshelf speaker system from KEF, built to run without a separate amplifier or source component. KEF has built a strong reputation for its Uni-Q coaxial driver technology across both passive and active product lines, and the LSX II brings that engineering into a fully self-contained wireless format.

Position in line

It sits below the larger LS50 Meta in KEF's active speaker range, sharing some acoustic heritage with the T301 in general compact-speaker positioning. This positioning below the passive LS50 Meta suggests the LSX II prioritises convenience and a wireless, all-in-one format over the ultimate scale the larger passive design can achieve with dedicated external amplification.

Key specs that matter

Rated response is 54 Hz to 28 kHz. Internal amplification totals 70 + 30 W across the pair's built-in amplifiers. At 24.0 x 15.5 x 18.0 cm and 7.2 kg it is a compact, desk-scale cabinet, small enough to sit comfortably on a desk or narrow shelf without dominating the space.

Sound and use context

Expect an immediate, source-integrated presentation typical of a wireless active speaker, with the amplification matched precisely to the drivers rather than left to a separate component - a genuine engineering advantage in a compact package, delivering KEF's Uni-Q coherence without needing a separate amplifier purchase.

Pairing

No external amplifier or source component in the conventional sense is used - streaming and wireless inputs connect directly to the built-in system, simplifying the whole setup to just this speaker pair.

Alternatives

The LS50 Meta moves into KEF's larger, passive monitor range for a system built around separate amplification instead, worth considering if the flexibility of choosing external electronics matters more than the LSX II's wireless convenience. KEF own app typically offers useful room-correction and EQ features worth exploring after initial setup, since these can meaningfully shape the final in-room sound beyond the raw driver and amplifier specification alone. Buyers should also confirm current firmware version and update availability, since KEF has a track record of adding features to its wireless active speakers well after initial release. Overall this remains a convenient, well-engineered choice for a desk or small-room wireless system. Firmware updates delivered wirelessly should be checked periodically after initial setup.
