KEF LS50 Wireless II Overview
The KEF LS50 Wireless II Book Shelf Speakers feature a proprietary Music Integrity Engine. This set of bespoke DSP algorithms optimizes the Uni-Q with MAT driver array to produce an incredibly tight, unsmeared sound. They're also equipped with plenty of power: each tweeter is driven by its own dedicated 100W Class A/B amplifier, while the mid/bass drivers are powered by 280W Class D amplifiers. The LS50 Wireless II is able to achieve this level of power due in part to the fact that KEF designed and manufactured its amplifiers in-house.
Setup and control of the KEF LS50 Wireless II is a breeze. The speakers are equipped with an OLED touchscreen and a "click" to allow you to easily toggle between Bluetooth and wi-fi. The speakers also let you adjust volume levels without using your smartphone.
