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.







The Uni-Q driver array uses an extremely light and rigid aluminium/magnesium cone designed to deliver fast and clean mid-range. With the aluminium tweeter, featuring KEF’s ‘Tangerine waveguide’ placed at the acoustic centre of the cone for optimum performance, not only will it increase dispersion and reduce the traditional ‘sweet spot effect’ making placement easy, but it’ll reproduce upper registers with startling clarity, smoothing the transition to midrange frequencies and reproducing your music with flawless accuracy.
