No Need for Cables or Amplifiers: KEF LSX II Wireless Powered Bookshelf Speakers Broaden the Sweet Spot, Provide Hassle-Free Convenience
Class-leading wireless powered speakers that double as a savvy all-in-one system, KEF LSX II offers a combined 200 watts of system power, compact form factor, versatile connectivity, and — most importantly — attention-holding sound. Equipped with there 11th generation of KEF’s signature Uni-Q driver technology, LSX II is anchored by a 0.75-inch vented aluminum dome tweeter and 4.5-inch magnesium/aluminum woofer — both of which are powered by their own dedicated amplifier. You can use the 9.5 x 6.125 x 9.25-inch (HWD) LSX II wirelessly (24-bit/48kHz) or, if you prefer, use the supplied Ethernet cable for enhanced 24-bit/96kHz performance.
Listening to music couldn’t be easier. Stream away via Apple AirPlay 2 and Google Chromecast, or straight from your phone, tablet, or computer. Enjoy DSD, MQA, and up to 24-bit/384kHz. The Roon-Ready LSX II does it all. Found on the right speaker, an HDMI ARC input links to your TV; a Toslink input welcomes CD and DVD players; an a USB-C input connects to computers. Want to add a subwoofer to the mix? A mono RCA input makes that possible — and the onboard Room EQ DSP means integration will be a breeze.
It goes without saying that the bass-reflex cabinet and curved front baffle, along with the color choices, make LSX II look great. Seamless compatibility with the KEF Connect app and a supplied remote control let you take command no matter where you’re sitting. KEF’s Music Integrity Engine, intuitive on-boarding setup, and a one-year manufacturer warranty round out a speaker that delivers size-belying clarity, definition, punch, and fun.

"I was delighted by their sound, their ease-of-use, and all the important improvements KEF worked into the LSX IIs. If anyone’s looking for a pair of wireless speakers that can do just about anything at a genuinely reasonable price, these should be at the top of the list."
—Drew Kalbach, The Absolute Sound
