KEF's Q-Series

KEF’s Q300 ($600/pair) is a 2-way, bass-reflex design with a 6.5” Uni-Q driver and 1” vented-aluminum tweeter utilizing KEF’s tangerine waveguide, said to reduce the acoustic resonances created by normal direct-radiating tweeters, improving the coupling between the tweeter dome and air. The speaker that was actually playing in the room, however, was the larger Q900 floorstander ($1600/pair), a 2.5-way, bass-reflex design with an 8” Uni-Q driver and 1.5” vented-aluminum tweeter and tangerine waveguide. Partnered with an inexpensive Denon player and Integra receiver, the sound was marked by quick, extended highs and controlled lows.
