    Overview

    Treat yourself to auditory magic with the KEF Q350 Bookshelf Speakers, radiating with a rich sound that is almost beyond belief. A minimalistic black exterior allows these speakers to fold unobtrusively into your home, resting amongst your books, plants, collectibles and more. Become captivated from the very first note that emanates from within this unit.

    Holding pride of place within the interior of the Q350 is KEF’s signature Uni-Q driver array. Placing the tweeter at the acoustic centre of the bass and midrange cone results in greater sound dispersion and consistency across all frequencies. The Tangerine Waveguide, mounted in front of the tweeter dome increases the stability and dispersion of sound created by the Uni-Q driver. Ensuring that you get the best sound possible, the Uni-Q driver has been repositioned to the centre of the cabinet to reduce internal resonance and sharpen audio detail.

    A damped tweeter loading tube improves treble performance by eliminating sound produced from the back of the tweeter. This is combined with the Computational Fluid Dynamics port design, improving the clarity of your audio by reducing the audibility of midrange leakage through the port. And finally, a low-distortion inductor on the crossover provides tight, dynamic bass that stays with you long after the last note has faded.
    Uni-Q Driver

    Using the power of NASA-developed magnets, KEF was able to develop a tweeter small enough to mount at the acoustic centre of the bass unit voice coil. This results in consistent and wide sound dispersion.

    Bass Port

    A flared port located at the rear of this unit amplifies the earth-rumbling bass tones of your audio, adding low tones you can truly feel.

    Hi-Res Audio

    This unit is a Hi-Res Audio device, which allows it to play a variety of 24-bit digital audio formats. This simply means you can take full advantage of high-quality audio sources like FLAC audio files.

    Contemporary Design

    Sleek elegance meets outstanding sound thanks to the practical minimalism of this unit. The smooth baffle and the patented Uni-Q shows off this unit's premium status.

    Definitely from the top shelf!
    I bought a pair of these Kef Q350 speakers and they are fantastic! The first thing I noticed from these speakers when I tested them was the warm sound that they produce. It's far less bright than a few other bookshelf speakers competing in this category. The next thing I noticed was the wide soundstage. It is detailed and full sounding. So much so that you could close your eyes and not know exactly where the source of the sound is coming from. When listening from an angle of 45 degs or more the Kef Q350 speakers keep a lot of the detailed quality and volume that most speakers in this category would lose well before this pair. I bought these speakers at $709. RRP in every store that sells these was usually $1,195. The front grilles came free with the order. So in total my savings were around $550AUD. At the price that Appliances Online had this beautiful pair of Kef Q350 bookshelf speakers, there was no a chance that I could turn down the opportunity that was presented to me. Now they sit either side of my turntable.
