A perfectly balanced, seamlessly integrated high end 5.1 sub/sat system based on KEF’s new 4.25” Uni-Q driver array and a superlative matching subwoofer, the new E305 home theatre system outperforms the competition by filling the room with a spacious, exquisitely detailed and compellingly natural soundscape that captures all the magic of the original performance.

New 4.25 inch Uni-Q driver array

The secret of the E305 system’s outstanding hi-fi response lies in the latest iteration of KEF's signature Uni-Q driver array, originally developed for the multiple award-winning Q Series. With its famously wide dispersion characteristics and sonic purity, this technology is what gives the system its extraordinarily natural sound quality.

Uni-Q Tweeter

The tweeter at the centre of the midrange cone is vented to prevent distortion-inducing high pressure from building up behind the dome, so the response in the critical vocal region remains intricately detailed with every nuance of the original recording. With KEF’s ‘tangerine’ waveguide, it encourages the sound to radiate evenly, increasing both the dispersion and sensitivity of the tweeter for a more natural performance throughout the listening area.

Uni-Q MF/LF Driver

Being stiffer than conventional materials, the aluminium midrange cone operates rigidly over the entire vocal range for the smooth, clear midrange response that reproduces the human voice with stunning accuracy. Together with KEF’s Z-flex cone surround it allows the cone full excursion while providing a smooth, uninterrupted surface over which the tweeter output passes with no disturbance or diffraction effects. Its undercut magnet designed driver motor, which usually is only found in high end speakers, reduces midrange distortion by generating a very symmetrical magnetic field, resulting transparency helps to create the feeling of ‘being there’.
