Key Features
The KEF LSX II LT Wireless Hi-Fi Speaker System features the same cutting-edge acoustic engineering as the LSX II, but with a more streamlined feature set, making it an ideal choice if you're looking for a cost-effective way to enjoy its award-winning sound. With HDMI ARC, USB-C, and optical inputs, you can connect the speakers to your hi-fi system, TV, or PC, providing you with a seamless plug-and-play experience without the added cost of an amplifier or AV receiver.
Wireless options are just as versatile, with Apple AirPlay 2, Google Chromecast, and Bluetooth support. This ensures you can stream music from services like Tidal, Qobuz, Spotify, or Amazon Music effortlessly, with audio quality up to 24-bit/384kHz for those who demand nothing less than high-resolution sound quality. The KEF Connect app lets you fine-tune settings like volume, EQ, and room acoustics, giving you a truly personalised listening experience, as well as multiroom potential with other KEF speakers around your home.
Complementing this is the Music Integrity Engine, a powerful digital processing tool that enhances the speaker's clarity and precision, allowing you to experience the same sound quality as the LSX II. At the heart of the system, the speakers retain KEF's 11th generation Uni-Q driver array, with the tweeter placed at the acoustic centre of the woofer. This design ensures truly rooming-filling sound without dead spots or drops in quality, allowing you to hear detailed audio without being confined to a single sweet spot.
