Both the LSX and LS50 Wireless share the same cohesive, dynamic, timbrally and tonally-rich sound signature courtesy of KEF’s patented Uni-Q driver. Aesthetically and technically speaking, the two models share a lot of the same DNA – the LSX looks like a miniaturizing ray gun was used on the LS50 – but the LSX benefits from more than a year of further research & development on KEF’s part into proprietary wireless-speaker connectivity, amplification and software/hardware interfacing.
