The KEF LS50 Wireless is a complete high-fidelity speaker system that redefines what compact active speakers can do. Inspired by the legendary passive LS50, this wireless version combines KEF’s iconic Uni-Q driver technology with custom-designed amplifiers and advanced digital signal processing for an exceptional, balanced soundstage that fills any room.
Each speaker houses two dedicated amplifiers — a 30W Class A/B amplifier for the tweeter and a 200W Class D amplifier for the mid/bass driver — ensuring detailed highs, rich mids, and deep, controlled bass. The Uni-Q driver array, with its 25mm aluminum dome tweeter at the acoustic center of a 130mm magnesium/aluminum mid-bass cone, creates a wide, three-dimensional sound field that remains consistent across the room.
With built-in Wi-Fi, Bluetooth 4.0, USB, optical, and RCA inputs, the LS50 Wireless easily connects to your preferred music sources — from high-resolution streaming services to traditional components. Controlled via the KEF Control and Stream apps, the system offers intuitive access to music libraries, tone controls, and advanced configuration options.
Elegantly designed and available in premium finishes, the LS50 Wireless is a sonic masterpiece and a design icon in one.
