Finding speakers that deliver true studio-quality sound without the hassle of external amps, DACs, and cables is every audiophile’s dream. Too often, “wireless” systems sacrifice fidelity for convenience — but the KEF LS50 Wireless II Powered Bookshelf Speakers prove you can have both. They’re not just speakers; they’re a complete high-end sound system engineered for those who crave precision, depth, and design excellence.
Whether you’re streaming Tidal Hi-Fi, spinning vinyl through an external preamp, or watching Dolby Atmos movies, the LS50 Wireless II bring every note and nuance to life with uncanny realism.
- Available streaming services include: Spotify Connect, Tidal, Amazon Music, Qobuz, Deezer, QQ Music, Internet Radio, and Podcasts.
- Each speaker consists of a 280 watt amplifier for the mid range and 100w amplifier for the tweeter.
Design & Build – A Work of Acoustic Art
The first thing you’ll notice about the LS50 Wireless II is their sculpted beauty. Crafted from curved, resonance-damped enclosures with a Carbon Black matte finish, these speakers are minimalist yet unmistakably premium. Every contour and material serves an acoustic purpose — reducing diffraction, controlling resonance, and delivering cleaner imaging.
At the center of each speaker lies KEF’s legendary 12th-Generation Uni-Q Driver Array, with its signature copper-colored cone. This design places the tweeter precisely at the acoustic center of the midrange cone, acting like a single point source to create a three-dimensional soundstage that fills the room, no matter where you sit.
The build quality is stunning — dense, solid, and built to last. From the smooth front baffle to the aluminum rear panel, the LS50 Wireless II exudes craftsmanship worthy of its price tag.
Sound Quality – Reference-Grade Clarity and Control
KEF designed the LS50 Wireless II to deliver the same performance as a full audiophile setup — DAC, preamp, and power amp included. Each speaker houses its own dedicated 280W amplifier for the midrange/bass driver and 100W for the tweeter, ensuring effortless power delivery and dynamic control.
Paired with KEF’s Music Integrity Engine, these speakers produce sound that’s incredibly precise, with zero distortion and perfect phase alignment. The result?
- Vocals sound pure and centered, as if the artist is performing live.
- Bass is tight, textured, and surprisingly deep for such a compact form factor.
- Treble is silky smooth yet detailed enough to capture the air around instruments.
Whether you’re listening to acoustic jazz, orchestral symphonies, or high-energy electronic music, the LS50 Wireless II adapts beautifully — presenting each genre with authority and emotional depth.
Even at high volumes, there’s no harshness, no compression — just transparent, effortless audio that rivals separate systems costing several times more.
Streaming & Connectivity – The Heart of a Modern Audiophile System
What makes the LS50 Wireless II so appealing is its complete integration. You don’t need an external DAC, preamp, or streamer — everything’s built-in.
