A gorgeous, versatile high-end audio solution
KEF LS50 Wireless powered speakers stand out from the crowd. They have a lot to offer, and when we heard them at our Charlottesville HQ, they really grabbed our attention. They're beautiful, compact, easy to use, and versatile enough to form the core of your everyday sound system. And you won't believe the rich, detailed sound they produce.

Audiophile sound quality
When you're going for that magical level of sonic realism that can raise goosebumps, one of the biggest challenges is matching the right amplifier to your speakers. So KEF has eliminated the guesswork: they put two custom-designed amplifiers in each speaker — 200 watts to each woofer, and 30 watts to each tweeter — so each driver gets perfect power. And the attention to detail doesn't stop there. Each driver has a high-end 192 kHz/24-bit DAC to make digital sound come alive.

Built-in digital signal processing (DSP) offers an easy Beginner mode, but you may prefer to take total control in Expert mode, and tweak the sound to perfectly suit your unique room. Whichever way you choose, you can make your changes via a free smartphone app, available for Apple® and Android™ devices.
