Listen to a wide range of sources
You can stream music wirelessly from a variety of sources via Wi-Fi using the popular Apple AirPlay 2 and Chromecast platforms. Or you can stream directly from phones, tablets, and PCs using Bluetooth. The right-hand speaker features a wealth of analogue and digital connections for hooking up a range of additional components, including:
- HDMI ARC input for connecting to a compatible TV
- Toslink digital optical input for TV, CD player, etc.
- USB Type-C for a compatible computer
- 3.5mm analogue aux input for a portable music player
- RJ-45 Ethernet input for network connection
- RCA Sub output lets you add a powered subwoofer for more bass
Audiophiles may appreciate the ability to make a wired connection between speakers via the included Ethernet cable for optimal sound, but the pair can also be linked wirelessly to allow for fewer cables and more flexible placement options.
Perfect power with Class D digital amplification
With traditional passive speakers you need to find just the right amplifier to match, with LSX II KEF has eliminated the guesswork by putting two custom-designed Class D digital amplifiers in each speaker — 70 watts to each 4-1/2" woofer, and 30 watts to each 3/4" tweeter — so each driver gets exactly the power it needs to produce the best possible sound quality.
DSP and room EQ for accurate sound
Custom-tailored digital signal processing (DSP) ensures Hi-Fi performance. And DSP-based room equalization lets you answer a few simple questions in the free KEF Connect mobile app (for Apple® and Android™ devices) to tune the speakers to your listening space.
Uni-Q technology provides wide "sweet spot"
The KEF LSX II features the 11th generation of KEF's patented Uni-Q driver, this places each speaker's tweeter in the acoustic centre of the bass/midrange cone. This allows the speakers to create a larger than normal "sweet spot" — the ideal listening position so that wherever you sit you can enjoy detailed, accurate, three-dimensional sound.
