Get to know this product.

With high resolution 96kHz/24-bit USB input and digitally connected hi-fi speakers, the X300A gives your music all the warmth, depth and detail of the original recording.

Hi-Fi Your Computer

Bringing true hi-fi sound quality to the tracks you play from your computer, laptop, tablet, MP3 player or smartphone, X300A digital hi-fi speakers feature KEF's sophisticated Uni-Q array, driven by two dedicated on-board amps - one for each frequency range. With a high resolution 96kHz/24-bit USB input and simple digital speaker connection, even familiar tracks suddenly seem incomparably richer, subtler and more emotionally powerful.

High Fidelity Design

Like a professional studio monitor, each X300A speaker has two dedicated class AB amplifiers - one for LF/MF and one for high frequencies – 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 clean USB input and digital connection between speakers, the X300A system turns your desktop, laptop, tablet or other mobile device into a source of listening pleasure to true high fidelity standards.

High Definition Sound

Carrying three times more data than the audio on a normal CD, the 24-bit/96kHz USB input allows the X300A system to reproduce the full depth and complexity of high resolution music files, and with distortion-free USB connection throughout, nothing is lost from the original source. In addition, a high quality DAC in each speaker virtually eliminates interference by separating decoding from playback. 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.

High Simplicity

Setting up and configuring the X300A couldn’t be easier – all you have to do is connect the speakers to each other and to your chosen device by the USB ports and plug into a power source. That’s it. No software to load, no fiddly programming. A 3.5mm analogue connection is included to connect your smartphone or MP3 player.

A balance switch on the back of the master speaker allows you to optimise the sound, whether you place the speaker on the desk, against a wall or in free space.

When your speakers are placed against a wall, you can insert the foam bung supplied into the rear reflex port for tighter, cleaner, bass performance.
