The secret of the E305 system's outstanding sound quality is 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 and sonic purity this technology is what gives the system its extraordinarily natural sound quality.

The Uni-Q tweeter is vented to prevent distortion-inducing pressure from building up behind the dome, keeping the response in the critical vocal region clean and transparent. KEF's 'Tangerine' waveguide encourages the sound to radiate evenly, increasing both the dispersion and sensitivity of the tweeter.

Uni-Q's rigid aluminium mid/bass cone delivers a smooth, clear response with stunning accuracy. KEF’s Z-flex surround provides a smooth, uninterrupted surface over which the tweeter’s output passes without diffraction. And its underhung magnet system reduces distortion by generating a highly symmetrical magnetic field.
