At last – the freedom to stream music wirelessly via Airplay® or DLNA from your computer, smartphone or any other mobile device in a way that allows you to experience uncompromised high fidelity sound. Everything about the X300A Wireless digital hi-fi speaker system is designed to make your enjoyment of music easier as well as more intense.
Like a professional studio monitor, each X300A wireless speaker has two dedicated class AB amplifiers – one for LF/MF and one for HF – to ensure accurate, distortion-free sound reproduction. Speaker hum and electromagnetic interference are minimised by using toroidal transformers of the type specified for audiophile grade hi-fi amps. With digital USB connection between speakers, the X300A wireless system turns your desktop, laptop, tablet or other mobile device into a source of listening pleasure to true high fidelity standards.
A dedicated high quality DAC in each speaker virtually eliminates interference by separating decoding from playback, allowing the X300A system to reproduce the full depth and complexity of high resolution music files to the same standard as the artist intended. All this high end technology is complemented by the award-winning Uni-Q ‘point source’ driver array derived from KEF’s flagship speaker, the Blade. The result is a spacious, accurate and exquisitely detailed sound field, whatever device your music is played from.
Configuring the X300A Wireless is easy – it takes only a few minutes, using the Setup Wizard on this site. A balance switch on the back of the master speaker allows you to optimise the sound for whether you place the speaker on the desk, against a wall or in free space. All you have to do then is power up your speakers and choose which tracks to start streaming.
The X300A Wireless is designed for both Apple (Mac OS X version 10.6 or later) and Microsoft (Windows 7 or later) operating systems, and you can stream your music by Airplay or DLNA from any Apple or Android device. To make the best streaming experience from your Android device, we offer an app allowing you to freely swap between different music libraries and stream the music you want, just download our KEF DMC app at Google Play.
