Introducing the KEF X300A digital hi-fi speaker system, an active design conceived to partner a PC or Mac, desktop or laptop computer. Simply connect the speakers via a ‘distortion free’ USB all-digital link to provide high resolution 96kHz/24 bit quality digital input and inter-speaker connection to ensure high definition sound from source to output.  Each speaker features twin class AB audiophile grade amplifiers inside, one for HF and one for LF/MF. Featuring high performance toroidal transformers and high quality DACs, with the X300A you don’t need to be an expert to enjoy audiophile sound quality.

Hi-Fi Your Computer

Featuring KEF’s state-of-the-art Uni-Q driver, supported by two amplifiers in each unit, the X300A is a true audiophile speaker for your PC, Mac, MP3 player or smartphone. Enjoy true high definition sound from source to output.

Just connect, power and play.

High Fidelity Design

With state-of-the-art technology that’s normally reserved for high fidelity, high quality audio equipment, X300A brings an exceptionally accurate sound to your desktop. Each speaker features twin class AB amplifiers – one dedicated to high frequency (HF) signals, the other to mid and low frequencies (LF/MF). The amplifiers' power supply uses a high performance toroidal transformer to minimise hum noise and electro-magnetic interference.

High Definition Sound

Enjoy your music, movies and gaming exactly as the creators intended. Using a 96kHz/24-bit input with digital inter-speaker connection – X300A retains, from source to output, every single byte of information without loss or distortion. To avoid signal jitter, which is created by the internal digital converter in your computer, smartphone or MP3 player, X300A has its own high quality DAC. All of which means, the sound you hear is exceptionally accurate.

To get the very best from the twin class AB amplifiers, an award winning Uni-Q driver design adapted from KEF’s flagship Blade speaker is featured in the X300A.

High Simplicity

With X300A you don’t need to be an expert to enjoy audiophile sound quality. Simply connect the speakers directly to your computer (and to each other) using an all-digital USB link. Then plug them into a power source and you’re ready to enjoy a genuine hi-fi experience. X300A also includes a backup analogue input so you can connect any smartphone or MP3 player and switchable EQ modes allow you to easily optimise the sound wherever you place your speaker (on a desk, against a wall or in free space).


High Fidelity Design

Innovation is what sets KEF apart from its competitors. For over 50 years KEF has been at the forefront of loudspeaker research and development, designing class-leading speakers that have dealt with the challenges of reproducing the latest musical formats, and reproducing them to the highest possible quality. The X300A continues this legacy today.

The X300A speaker is a premium active design conceived to offer the highest resolution music reproduction from a PC or Mac, desktop or laptop computer – all via a ‘distortion free’ USB digital input. There is even a backup analogue input with its own level control so you can easily connect any smartphone or MP3 player.

Unlike typical active computer speaker designs the X300A utilises twin class AB audiophile grade amplifiers featuring high performance toroidal transformers to minimise hum noise and electromagnetic interference, in keeping with the best pro audio monitors available today. This means that because each driver has an amplifier delivering its own power, the tweeters (vented designs to help lower distortion) are not affected when the woofer amps are driven close to the limit, resulting in a much cleaner sound and greater control at higher levels.
