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 Coda

 KEF Coda (1971-77)
The Coda was developed from the ground breaking Cresta design with some useful design elements to provide excellent acoustical performance in an economic package. Its accurate, wide frequency response made it ideal for high quality stereophonic systems in small to medium sized rooms and the dimensions allowed convenient installation in the new, but short lived, quadrasonic format.
 The Coda is a totally enclosed speaker box of 7,26 liters, fitted with two drive units.
Its accurate, wide frequency response makes it ideal for high quality stereophonic systems in small to medium sized rooms. Its dimensions ideally complement quadrasonic installations.
