What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

KEF Q60


 Why "Q"
KEF's Uni-Q two-way coincident-source drive unit is incorporated into all three "Q" series models. This unique drive unit combines both tweeter and bass/midrange units into one single chasis. This radical KEF development allows the sound from both units to reach the listener's ears at the same time, bringing readily audible benefits in terms of transparency, image stability and more natural sound reproduction.Uni-Q speakers are highly versatile in use. Being less affected by differing room acoustics, they will operate well in a wide range of placements and listening positions. Furthermore, an advanced and innovative design feature, unique to KEF ensures that all three Q-Series models share quite exceptionally low levels of cabinet colouration, even at high volumes.


 KEF Q60
Fast, well controlled bass performance with accurate, detailed, midrange and the capability to play at realistic levels with modest power requirements sums up the remarkable Q60. Designed for stand mounting 400-450 mm (15' - 18') high, a 200 mm (8') Uni-Q bass-midrange unit, with 25 mm (1') NIB magnet tweeter centrally placed, is loaded by a 20 litre reflex enclosure, 18 mm (3/4') thick. Careful bass alignment makes the Q60 tolerant of positioning, with the ability to recreate the life-like three-dimensional qualities of well recorded music in almost any environment.
