Legendary sound quality Based on the now legendary KEF LS50 speakers, this wireless system version gets off to the best of starts. At their heart is KEF's Uni-Q technology. This places both drivers on the same axis, giving smooth, cohesive sound and an immersive soundstage. Enhancing this further is an advanced time-correcting DSP (Digital Signal Processor) crossover.
Unique to these speakers, the technology corrects and adjusts the speakers' output - ensuring the sound reaches you at the optimum balance - whatever your room size or shape. Powerful sound Featuring a dedicated 200 watt amplifier for the woofers (plus a 30 watt amp for the top end), the LS50W is never short on grunt. Carefully matched to get the very best from the speakers, the amplifiers deliver clean, effortless power to give these speakers bite with all types of music.
If even this isn't enough, a dedicated sub output lets you connect your own choice of active subwoofer. High Resolution DAC - built-in With 192kHz/24 bit DACs (Digital to Analogue Convertors) built into each speaker, the KEF LS50W makes the ideal partner for your Hi-Res music. Stream over Ethernet or Wi-Fi or use the USB connection to enjoy the best quality. With the optical input the potential isn't quite as high but is a still a CD-busting 96kHz/24 bit. One pair of speakers does it all - wirelessly For the best quality music streaming, you can link up to the KEF's Ethernet or Wi-Fi interface.Quick and easy wireless playback is also possible via Bluetooth. With aptX compatibility, this means you get the best Bluetooth sound possible from your smartphone or tablet. Or, cable it up Thanks to its optical and analogue RCA phono inputs you can also connect up other sources, such as your TV, games console, CD player or turntable (with built-in pre-amp).
An asynchronous USB connection gets the very best from music stored on your computer and makes the perfect connection for playing back the highest quality Hi-Res music files.
