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 Chorale

 Chorale (1970-79)
The Chorale paired a B200 with the established T27 tweeter in a 20 Litre closed box design, which became an instant success and KEF’s new best selling product. It combined an extended high frequency response with a natural, uncoloured midrange and a full round, bass - quiet and delicate or complex and heavy music being handled with equal ease. The success of the Chorale ensured that it remained in production until 1979.
