KEF LSXII-SW Wireless Hi-Fi Speakers – Soundwave by Terence Conran
Precision Engineering Meets Iconic Design
The KEF LSXII-SW Soundwave Edition represents a perfect fusion of British design heritage and cutting-edge audio engineering. Compact yet immensely powerful, these wireless bookshelf speakers deliver high-fidelity sound that fills your room with incredible detail, depth, and stereo imaging. At the heart of the system lies KEF’s award-winning Uni-Q® driver array, which places the tweeter at the acoustic center of the midrange cone, producing a coherent, three-dimensional soundstage with minimal distortion.
The LSXII-SW is powered by a dual-amplification system: a 70W amplifier for the low-frequency driver and a 30W amplifier for the tweeter. This allows each component to perform optimally, whether you’re listening to delicate acoustic tracks or room-filling orchestral pieces. With a total output of 200 watts, these speakers provide punchy, precise, and balanced sound, adaptable to virtually any listening environment.
Soundwave by Terence Conran – A Design Statement
These speakers are more than just audio devices; they are a celebration of design excellence. The Soundwave Edition features Terence Conran’s signature pattern woven into high-quality Kvadrat fabric, offering a tactile and visually striking finish that complements modern interiors. Conran’s philosophy of functional beauty shines through: the LSXII-SW blends style, form, and function seamlessly.
Every curve and detail has been carefully considered. The result is a speaker system that not only sounds exceptional but also elevates the look of any living space, from contemporary apartments to classic home studios.
Seamless Connectivity
The LSXII-SW is engineered to connect effortlessly to a wide array of sources:
-
HDMI ARC, Optical, USB-C, and 3.5mm Aux inputs for TVs, computers, gaming consoles, and more
-
Wi-Fi and Ethernet support for high-quality network streaming
-
AirPlay 2, Chromecast, Bluetooth 4.2, and Roon Ready compatibility
Whether you want to stream Spotify, TIDAL, Qobuz, Deezer, or Amazon Music, or play files from a laptop or NAS, the LSXII-SW adapts without compromise. The included KEF Connect app makes controlling your music simple, offering EQ settings and multi-room streaming options at your fingertips.
High-Resolution Audio & Immersive Experience
Designed with audiophiles in mind, the LSXII-SW supports DSD and PCM up to 24-bit/384kHz, as well as MQA for TIDAL Masters. These speakers faithfully reproduce every nuance of your recordings, from subtle room ambiance to powerful bass.
Thanks to wireless stereo separation, the two speakers create a wide, immersive soundstage. For maximum low-end impact, a dedicated subwoofer output allows integration with your preferred active subwoofer, giving you the flexibility to tailor the system to your room size and listening style.
Smart Streaming & App Control
Take full control of your listening experience with the KEF Connect app. You can:
- Stream directly from Spotify Connect, TIDAL, Qobuz, Deezer, Amazon Music, and more
- Access internet radio and podcasts easily
- Adjust EQ settings to suit your room acoustics or personal taste
- Set up multi-room playback effortlessly
The app transforms the LSXII-SW into a central hub for all your music, whether local files, online streaming, or networked storage.
Stylish, Compact, and Flexible
Despite its compact form, the LSXII-SW delivers room-filling sound without compromise. Curved cabinets, premium fabric finishes, and Terence Conran’s distinctive Soundwave design make this speaker system as visually compelling as it is sonically impressive. Available in Soundwave edition plus high-gloss and fabric finishes, these speakers integrate seamlessly into living rooms, studios, or desktop setups.
Why the KEF LSXII-SW Stands Out
- Premium sound in a compact footprint
-
Terence Conran design signature with Kvadrat fabric finish
- Multiple wired and wireless connectivity options
- High-resolution and MQA support for audiophile-quality playback
- Flexible EQ and subwoofer options for customizable sound
- Intuitive app control for streaming, multi-room setup, and internet radio
