Putting together a new high-quality audio system? Then consider KEF's Q150s. These attractive bookshelf speakers create a wide soundstage with pinpoint imaging. Use them as part of a stereo music system, or as left- and right-channel speakers in a KEF Q Series home theater system.
An expanded view of the Uni-Q driver assembly shows the detailed design and build quality that goes into making each Q150.
A room-filling "sweet spot," thanks to Uni-Q® technology
KEF's patented Uni-Q technology places each speaker's 1" tweeter in the acoustic center of the 5-1/4" woofer. This concentric design allows sounds to originate from a single point source, making the "sweet spot" (the ideal listening position) much larger.
Here at Crutchfield, we've had the pleasure of hearing Uni-Q technology in person many times. Sit wherever you like — you'll enjoy detailed, accurate three-dimensional sound throughout your room.
Get the most out of your stand-mount speakers
I'm a proponent of using high-quality speaker stands with "bookshelf" speakers. They help improve the sound by giving your speakers a stable, vibration-free platform. When shopping for stands, remember that the ideal height will place the tweeters roughly level with your ears, for maximum clarity. 
Speaker stands also give you more placement flexibility, since you won't be limited to a space on your shelf or table. The Sanus SF26 steel stands are an excellent choice to use with these speakers,
