The KEF Q150 is a compact speaker with clear sound performance. This speaker has the Uni-Q system. This means that the 25mm tweeter is positioned in the center of the 130mm woofer. This leads to a detailed sonic image that is distributed widely throughout the room. The woofer producing the mid tones and bass is combined with a bass reflex port. This makes the bass tones sound extra rich. You use the 2 speakers as stereo pair or as part of a surround setup. The compact design makes it easy to place these in your room.
