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.

 Recent developments in loudspeaker engineering and new analysis techniques for evaluating acoustical performance, have resulted in KEF preparing three new loudspeaker products featuring:
Computer design filter sections of advanced specification.
Enclosures heavily damped and braced to minimise colouration
Generous power handling capabilities.
Corelli was an 8 inch two-way closed box system that built on the success of the Chorale. The developments included a new version of the B200 bass unit and an improved cabinet.
