KEF Q-550 Floor Standing Speaker Set of Pair- Total Dynamic Power Handling Each Watts- 200 W Tower Speaker  (Black, 2.0 Channel)

"Sit anywhere" uni-q sound At the heart of the evolved q series is the uni-q driver array. The signature innovation places the tweeter in the acoustic centre of the midrange and bass cone, bringing the acoustic ideal of a single point source closer than ever to realisation. The result is a more detailed, accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with any conventional speaker. Uni-q's ultra-wide dispersion is further enhanced through kef's 'tangerine' waveguide over the tweeter dome. Damped tweeter loading tube Damped tweeter loading tube With the addition of the damped tweeter loading tube providing a gentle termination of sound produced from the back of the tweeter, lower treble performance is improved dramatically and a new low-distortion inductor on the crossover provides cleaner bass. New system design New system design The closed box midrange cabinet design reduces the load on the uni-q midrange cone, increasing clarity and detail while delivering cleaner, punchier bass. Midrange clarity is enhanced again through improvements to the mid-bass driver that allowed the dc blocking capacitor to be eliminated. Its removal also created a more natural bass roll-off between the drivers. Beefier lf drivers and abrs Beefier lf drivers and abrs Low-frequency (lf) drivers now have a larger roll surround, along with a new suspension to produce cleaner bass at high volumes. A new cone structure improves midrange clarity, and an enhanced auxiliary bass radiator (abr) with a new surround and rear suspension delivers better controlled and more impressive bass.
