KEF LSX Wireless Music System Price Drop

KEF’s multi-award winning LSX Wireless Music System will be going on sale starting today (through the end of the year) for $999 USD, a $250 USD savings.

The diminutive little brother to KEF’s LS50 series, was my Product of The Year for 2018, and is one of the most impressive true wireless powered-loudspeaker implementations I have experienced at this price point. Read my full review HERE.

Both the LSX its critically-acclaimed (and best selling) big brother, the LS50 Wireless, are cut from the same cloth when it comes to their sound signature, think; cohesive, dynamic, with a clean, resolution-tipped timbral and tonally accurate frequency response. Featuring KEF’s patented Uni-Q driver (0.75-inch aluminum dome tweeter, 4.5-inch magnesium/aluminum-alloy midbass-woofer), the little LSX measures just 9.5 x 6.1 x 7.1 inches and weighs 7.9 (master) and 7.7 pounds (slave).

The LSX comes in five colour choices: white, red, green, blue and black and will support input resolutions up to 24-bit/192kHz. Output is 24-bit/48kHz for wireless playback and 24-bit/96kHz for RJ45 tethered playback. The LSX connect wirelessly via 2.4GHz/5GHz dual-band wi-fi, Bluetooth 4.2 with the aptX codec (10-metre range, up to eight devices), or hard wired via RJ45 Ethernet. Apple Airplay 2 is now standard. A TOSLINK Optical and a 3.5mm auxiliary input are also included. The LSX also has a 5V2A DC subwoofer output.
