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.

B&W CD-5

 CM5 is a slighty larger speaker than its sibling the CM1, with even higher sensitivity and power handling, and better bass extension. It partners a sizable 165 mm kevlar cone bass/ midrange driver with a Nautilius tube loaded aluminium dome tweeter, capable of keeping high frequencies crisp and sharp all the way up to 50 kHz and beyond.
