KEF LSX II LT - Active Wireless Loudspeakers (LSX2 LT)

KEF LSX II LT - Active Wireless Loudspeakers (LSX2 LT)

High-Fidelity Sound at an Accessible Price

The KEF LSX II LT delivers high-fidelity sound with the same fundamental technology used in the LSX II, at a more accessible price. The KEF LSX II LT operates on KEF's Music Integrity Engine (MIE) and the same 11th-generation signature Uni-Q driver array found in the standard LSX II to produce accurate and immersive sound from digital, streaming and vinyl playback. 

The LSX II LT can stream music in up to 24bit/384kHz over Apple AirPlay 2, Google Chromecast, and Spotify Connect, ensuring that every detail is captured sonically for a high-fidelity listening experience. 

The LSX II LT is integrated with the W2 wireless platform, allowing it to sync with additional speakers from the LS Wireless Collection for multi-room playback. Connect KEF LSX II LT speakers directly to your TV or computer via the built-in HDMI ARC and USB-C ports. Optical inputs are also available for connection to other audio equipment. 

The LSX II LT distinguishes itself from its counterpart with a simplified single-cable setup. The LSX II LT’s primary speaker only requires a single mains lead, as the second speaker draws power through the supplied USB-C interspeaker cable. However, the LT omits the standard model's analogue aux input. 

KEF LSX II LT shares the same compact dimensions as the standard LSX II (240 × 155 × 180 mm), and is available in three coloured finishes.

Compact, Streaming Bookshelf Speakers

In our books, the true value of the LSX II LT lies in the single-cable design and uncompromising high-fidelity sound. Featuring the same 11th-generation Uni-Q driver array and Music Integrity Engine as the LSX II, the sonic performance of the LT is indistinguishable from its standard counterpart. 

As the primary speaker is connected to the mains, the speaker offers a simplified system that sits neatly on a shelf or desktop. Wireless connectivity is available across Wi-Fi and Bluetooth 5.0, with the option to pull media directly from a NAS drive or music server. 

The difference is that the LSX II LT does not come Roon-ready, has no analogue 3.5mm aux input for a turntable, and its speakers must be physically connected via the USB-C cable.
