LS50 Wireless II
About
KEF spent decades refining their Uni-Q driver technology, which positions the tweeter concentrically within the midrange cone to create a single point source for all frequencies. The LS50 Wireless II represents the current culmination of this research, pairing the 12th-generation Uni-Q driver with Metamaterial Absorption Technology that eliminates the high-frequency distortion typically caused by sound waves reflecting inside cabinet enclosures.
Each speaker houses its own amplification rather than relying on external components. A 280W Class D amplifier drives the bass frequencies where power demands peak, while a separate 100W Class AB amplifier handles the tweeter with the linearity that high-frequency reproduction requires. This bi-amplified configuration allows dedicated digital signal processing for each frequency range, optimizing crossover behavior and room correction with precision impossible in passive speaker systems.
The cabinet construction contributes significantly to sound quality. Curved surfaces reduce internal standing waves while the constrained layer damping within the walls converts mechanical resonance into negligible heat rather than audible coloration. External finish options span neutral tones that recede into living spaces alongside bolder statements for those who want their speakers to participate in room aesthetics rather than hide from them.
Wireless connectivity spans WiFi streaming, Bluetooth, and direct connections to turntables or televisions. The accompanying app provides room correction calibration, source selection, and tonal adjustments. For listeners who want exceptional stereo reproduction without the complexity of component separates, rack-mounted amplifiers, and cable management, the LS50 Wireless II consolidates audiophile-grade performance into a system that occupies bookshelf space and connects with a single power cable per speaker. The sound reaches into recordings with clarity that reveals details casual systems obscure.
