Evolution of Acclaimed Sound:

The KEF LSX II marks the evolution of the highly praised LSX system, now featuring HDMI ARC, USB-C connectivity, and advanced DSP software. With a power output of 200 watts and the innovative W2 streaming platform, this next-generation system redefines the home audio experience.

Versatile Connectivity:

The LSX II offers unparalleled connectivity options, seamlessly integrating with major streaming services through the KEF Connect app. Supporting services like Amazon Music, Qobuz, Tidal, Deezer, and internet radio, it also features compatibility with AirPlay 2, Google Chromecast, Roon, and Bluetooth. The addition of HDMI ARC and USB-C ports enhances its versatility, making it one of the most flexible audio systems available.

Uncompromising Sound Quality:

Ideal for various spaces, including 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 with exceptional detailing, creating a listening environment characterized by pristine and natural sound reproduction.

11th Generation Uni-Q Driver:

At the core of the LSX II are KEF's proprietary 11th generation Uni-Q drivers, meticulously tuned for this system. Placing the tweeter at the center of the woofer 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.

Impeccable Design:

Designed in collaboration with industrial designer Michael Young, the LSX II boasts impeccable aesthetics. From the elegant rear panel to the subtle design accents on the drivers and ports, attention to detail is evident. With six stunning finishes, 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.

User-Focused Experience:

The KEF Connect app simplifies the user experience, guiding through setup and providing intuitive control. Integrating all streaming services in one place, it offers sound settings for personalized audio in any room. The Room EQ DSP fine-tunes audio to room acoustics, and features like volume settings, sensitivity adjustments, and source selection enhance the overall experience. The system offers both wireless and wired use, allowing versatile placement without cable clutter and delivering immersive, full sound from any source
