Awards and press

“KEF has carved out a strong niche for itself in the past few years with its wireless active designs. It’s easy to see why, as they tick so many boxes and offer easily accessible, high-performance speakers in neat, versatile packaging. LSX II epitomises this, with excellent wireless connectivity, a versatile range of functions, crisp, modern styling and class-leading sound. As with its predecessor, LSX II is the one its rivals want to beat.” - StereoNET, December 2022
