KEF X300A Wireless Active Bookshelf Speakers


The wireless edition of the X300A gives you the precision and emotional intensity of true hi-fi sound, simply by streaming your favourite tracks via Airplay or DLNA.


    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.


    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.
