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.

Bozak B-201 Sonora

 Sonora
Model B-210
Desgned for the discriminating music lover who has restricted listening space or budged, the Sonora represents the ultimate accomplishment in two-way speaker desing. Among bookshelf speakers it is distinguished by the openness, clarity and solidity of its sound. Its efficiency is such that it provides faitful reproduction even when driven by the low-powered amplifiers in music systems designed for smaller rooms.
 To approach the perfection of three-way Bozak systems, Bozak engineers had not only to develop a special component speaker to handle the bass and midrange frequancies, but also to devlop a vented enclosure to  assure open bass tones.
The wide-range Model B-800B speaker employs a spun aluminum cone of patented design to provide a combination of rigidity with low mass and high compliance to permit outstanding transient response over a broad frequency range. The lightweight cones allow faithful reproduction at even low amplifier powers, but, since its aluminumcones dissipiate heat, it is capable of handling in excess of 60 watts of power -  power handling capability unusual in a speaker of its size.
For the treble frequencies, a single unit of Bozak's celebrated B-200Y tweeter is employed. A passive L-C network provides crossover between the two component speakers at a frequency of 1800 Hz and at s smooth 6 dB/octave raate.
