    Overview

    Created for the faithful reproduction of vocals and the seamless flow of music across your entire speaker system, the KEF Q650c transcends simple audio. When watching movies and TV, the centre channel speaker serves to be the main source of vocals, making it feel as if they are talking directly to you. When listening to music, the centre speaker widens the soundstage for broader sound dispersion and smooth audio.

    Utilising the signature KEF Uni-Q driver array, this Q650c gifts you with clear, three-dimensional sound that simply fills the room. This is achieved through mounting the tweeter onto the bass and midrange cone, allowing this unit to disperse audio more evenly. Furthering this is the Tangerine Waveguide dually reducing unwanted acoustic resonance and enhancing sound dispersion.

    KEF hasn’t forgotten the bass either, with the closed cabinet design of the Q650c as well as the low-distortion inductor on the crossover providing tight, dynamic bass that you truly feel within yourself. This is driven by a 6.5 inch woofer and complemented by an Auxiliary Bass Radiator on the front face of the unit, passively increasing the impact of the bass.
    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.

    Auxiliary Bass Radiator

    Increasing the effectiveness and punch of the lower tones, an enhanced Auxiliary Bass Radiator provides clearer and more impactful bass.

    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.
