2013 Product of the Year Entrant
The X300A is a premium loudspeaker system that offers the highest sound reproduction possible from computers via distortion-free USB input, as well as smartphones and tablets, including Apple iPod, iPhone, iPad, Android and Kindle Fire devices via auxiliary input.
X300A speaker features two built-in Class AB audiophile-grade amplifiers (one dedicated to HF ranges and the other for LF/MF ranges) complete with a toroidal transformer, which significantly reduces the normal “hum” heard while playing most powered speakers.
The X300A also features KEF’s patented Uni-Q driver array which places the tweeter in the acoustic center of the woofer. This allows the speaker’s woofer and tweeter to act as a single, focused source of sound that is dispersed widely and evenly throughout a room.
The X300A was designed to mirror the performance of the best in professional studio monitors with an impressive output of 150W of power per channel at 1kHz.

Unlike typical powered computer speaker designs, each X300A speaker utilizes two Class AB audiophile-grade amplifiers - one for high frequency and one for low/mid-frequency - complete with a toroidal transformer, which significantly reduces the normal "hum" heard while playing most powered speakers. To get the very best from the twin class AB amplifiers, the X300A features KEF's patented Uni-Q driver array, adapted from KEF's flagship speaker, Blade. KEF's Uni-Q array places the tweeter in the acoustic center of the woofer. This allows both the woofer and tweeter to act as a single, focused source of sound that is dispersed widely and evenly throughout a room or setting - a feature not found on any other loudspeaker brand.
The driver array is neatly housed within a die-cast aluminum chassis to help prevent resonances and creates a more accurate sound. With other innovations such as the Z-flex surround for a smooth transition between cone and cabinet, and large neodymium magnets with copper caps to reduce inductance and distortion, the Uni-Q driver array provides a wide, clean and detailed sound field, whatever source your music is coming from.
The X300A's USB connection provides lossless, high-resolution sound from any computer, smartphone or tablet courtesy of a 96kHz/24-bit digital input featuring an integrated audiophile-quality digital/analog converter (DAC) in each speaker. This assures that when a listener connects to the X300A, they will bypass the source's internal DAC resulting in accurate, high resolution playback from whatever source is connected, whether it's a phone, tablet or computer.
‘Of all art, music is the most indefinable and the most expressive, the most insubstantial and the most immediate, the most transitory and the most imperishable. Transformed to a dance of electrons along a wire, its ghost lives on. When KEF returns music to its rightful habituation, your ears and mind, they aim to do so in the most natural way they can … without drama, without exaggeration, without artifice’. Raymond Cooke, KEF founder
The company was founded in 1961 by Raymond Cooke OBE (1925–1995) and was initially headquartered in a Nissen Hut on the premises of Kent Engineering & Foundry (from where the name KEF is derived) – a metal-working company on the banks of the River Medway, near Maidstone in Kent. Cooke, an ex-BBC Electrical Engineer, was keen to experiment with new materials and technologies in order to create products with superior acoustic quality that could reproduce recordings as natural as the original performance. From the very beginning, the pioneering inventiveness of KEF loudspeakers was undeniable and now for several decades, audiophiles around the world have revered KEF for its innovative, high-performance loudspeakers.
