KEF Q300 Bookshelf Speakers


The multi-award winning Q300s are the largest of the Q Series bookshelf speakers, containing the very latest and refined version of the Uni-Q driver array, measuring in at 165mm (6.5in). The Q300s deliver lush, spacious and precise sound, with compelling midrange/HF response and sold, immaculately controlled bass. Everyone in the room is enveloped in the same beautifully integrated sound image.


  • A class above

    Whether as main speakers, music speakers for your study or family room, rear speakers in a home theatre system or general purpose speakers for multi-room set-ups, the two Q bookshelf models open up a world of audiophile quality sound at a surprisingly affordable price.

    With 135mm (5.25in.) Uni-Q driver array, Q100 delivers all the benefits of the Uni-Q 'point source' configuration in its latest and most refined form: a more accurate sound image dispersed more evenly throughout the room than is possible with any conventional speaker.

    Subjectively, it makes a huge difference. Because everyone in the room is enveloped in the same beautifully integrated three-dimensional sound image, viewing becomes more of a shared experience – and you no longer have to stay in the same spot to get the full enjoyment from your favourite tracks

  • Uni-Q driver array

    Sweet, spacious and true, wherever you sit.

    Thanks to the latest computer modelling techniques, years of painstaking development and a dash of design genius, the new iteration of the Uni-Q concept packs a formidable complement of design innovations. Based on the state-of-the-art HF driver developed for Concept Blade, the Q boasts a much larger (25mm/1 in. dome) tweeter for increased sensitivity and distortion-free power handling. It plays as loud as it plays true.

    Advanced bass technologies

    Deeper, tighter and more accurate bass.

    Featuring rigid new aluminum cone technology just like the Uni-Q array, the Q Series advanced bass driver is a tour de force in its own right. A die-cast aluminum chassis rigidly locates the high efficiency vented magnet assembly to prevent unwanted resonance, and the large (50mm) voice coil ensures impressive power handling. Its musicality is impeccable: seductively tuneful and well controlled, and on the floor standing models, complemented by dedicated front-firing auxiliary bass radiators (ABRs).

    Total system design

    A holistic approach with no compromises.

    The performance envelope of these sensational new drive units is so generous that the signal needs minimal intermediation - simple first order crossovers are all that's required, as you can tell from the transparency of the sound and the inaudibly fluent transitions.
