Introduction

Over the years, KEF has released 11 different versions of their Uni-Q drivers. That just shows you the importance KEF places on keeping their products at the forefront of the latest technology. KEF’s newest version of their Uni-Q driver is the design centerpiece in the All New Q Series. The Q300’s are the larger of two bookshelf models in the line.

The engineering team that developed the drivers for the All New Q Series is the same team that did the Concept Blade project. Naturally, many of the concepts implemented in the Blade design have trickled down to the Q300’s. Ultimately, the two projects resulted in four patented technologies: the Tangerine Waveguide, Optimal Dome Shape, Stiffened Dome and the Z-Flex Surround.

The Uni-Q drivers combine the tweeter and midrange into a single assembly. The drivers emulate a “single acoustic source coherent in position, directivity and time.” I have been impressed with the Uni-Q speakers I’ve heard in the past. So I was really looking forward to testing the new models.
