The LSX II offers a plethora of connectivity options. It seamlessly integrates with major streaming services such as Amazon Music, Qobuz, Tidal, Deezer, and internet radio stations via the KEF Connect app. This all-in-one system also supports AirPlay 2, Google Chromecast, Roon, and Bluetooth.

Uncompromising Sound Quality
Perfect for living rooms, home offices, and studios, the LSX II supports a wide range of file formats, including DSD, MQA, and PCM files up to 24-bit/384kHz. This ensures high-resolution audio quality and exceptional detailing, creating a listening environment characterized by pristine and natural sound reproduction.
11th Generation Uni-Q Driver
At the heart of the LSX II are KEF's proprietary 11th generation Uni-Q drivers. These drivers have been meticulously tuned for this system, with the tweeter precisely placed at the center of the woofer. This design eliminates the "sweet spot" associated with generic two-way speakers, delivering accurate and pristine sound. With a combined 200 watts of system power and dedicated amplifiers for each tweeter and woofer, the LSX II offers room-filling sound typically found in larger units. The Music Integrity Engine employs advanced algorithms to ensure perfectly timed performance, improved clarity, and a tight, accurate sound.
The LSX II boasts an impeccable design created in collaboration with industrial designer Michael Young. Attention to detail is evident in every aspect, from the elegant rear panel to the subtle design accents on the drivers and ports. With six stunning finishes to choose from, including Mineral White, Lava Red, Carbon Black, Olive Green, Cobalt Blue, and The Soundwave by Terence Conran Edition, this system complements any environment or lifestyle.
The KEF Connect app simplifies your experience, guiding you through setup and offering intuitive control of your system. It integrates all your streaming services in one place and provides sound settings for personalized audio in your room. The Room EQ DSP fine-tunes audio to your room and preferences, with additional features like volume settings, sensitivity adjustments, and source selection. The system can be used wirelessly or wired, allowing versatile placement without cable clutter and delivering immersive, full sound from any source.
