KEF LSX II LT Powered Hifi Speakers (Pair) – Graphite Grey
Drawing upon over 60 years of experience in acoustic excellence, KEF is driven by the pursuit of making high-fidelity sound accessible to all. The LSX II LT Wireless HiFi Speakers embody this mission, presenting a streamlined version of the LSX II, an award-winning compact wireless HiFi system that delivers pure, accurate sound while offering the compatibility and convenience of cutting-edge technology.
Retaining the remarkable acoustic performance and core features of the LSX II, the LSX II LT speakers also incorporate the iconic Uni-Q driver array, renowned for its natural, accurate sound reproduction. Equipped with the W2 wireless platform, they allow effortless music streaming as well as plug-and-play functionality with TV, desktop computer systems, and more. Designed by Michael Young, catering to various aesthetic preferences.
Play all the music in the world
At the digital heart of the LSX II LT sits the same cutting-edge W2 wireless platform that drives the LSX II. This ensures that no matter how you like to listen to music, you can do so with the minimum of fuss and in pristine sound quality.
The KEF Connect app lets you stream Amazon Music, Qobuz, Tidal, Deezer, Internet Radio stations, and podcasts. Apple AirPlay 2 and Google Chromecast seamlessly stream audio from compatible devices, whilst Bluetooth expands the options even further. You can use native apps to stream directly from Spotify Connect, Tidal, and QPlay. When using Airplay 2 or Chromecast you can stream to multiple speakers, so you can play music all over your house.
If that wasn’t enough, LSX II LT can also play your private music collection from a compatible NAS drive or music server. Plus, audiophiles are covered with extensive file support up to 24bit/384kHz (PCM) and DSD.
Plug and play to TV and desktop
Alongside Wi-Fi and Bluetooth, LSX II LT also boasts an extensive collection of wired connections. These include HDMI ARC for seamless control using a TV remote and a high-quality USB-C input, making LSX II LT the perfect desktop system with your computer. There is also an optical input for your CD player, game console, and many other devices. If you demand your movies and music come with extra bottom end, there’s a dedicated subwoofer output, allowing you to connect a KEF subwoofer for the bass you crave.
High-Fidelity sound
Each LSX II LT speaker uses a version of KEF’s 11th generation Uni-Q driver array, specially designed for this loudspeaker. This signature technology acts as a point source, where the tweeter is placed at the precise acoustic centre of the woofer, recreating how sound is produced naturally. This design eliminates the traditional, tiny ‘sweet spot,’ instead delivering accurate, pristine sound to all listeners.
LSX II LT has a combined 200 Watts of system power. Both the primary and secondary speakers are equipped with dedicated amplifiers for the tweeter and woofer, ensuring the delivery of room-filling sound in its remarkably compact cabinets.
Performance is further enhanced by the Music Integrity Engine. This cutting-edge collection of bespoke Digital Signal Processing algorithms is optimized for the Uni-Q driver, enabling the LSX II LT to deliver a perfectly timed performance, resulting in better clarity and a tighter, more accurate sound.
