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 Cadenza

 Cadenza (1970-76)
The Cadenza combined a B200 with the established T27 tweeter and BD139 passive radiator in a 45 Litre design, a format that was later developed into the Reference 104. Although relatively compact the Cadenza was suitable for use in larger rooms and was capable of fundamental tones down to 30Hz. This was achieved by means of the acoustically coupled passive radiator, which worked in conjunction with the bass driver to enhance the bass output.
