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.

RADAX Coaxial Speaker

The Radax extends both bass response and high-frequency reproduction in pleasing musical balance-insures improved coverage of the entire listening area-minimizes distortion.

 

 

This exclusive E-V development achieves highest efficiency with economy. Two separate coaxially-mounted cones operating from a single voice coil, divide the audible spectrum. Each is specifically designed to reproduce its portion of the audible range. The large cone "woofer" provides maximum bass reproduction; the small cone gives effective high-frequency propagation. True mechanical crossover permits smooth transition and reproduction of lows and highs in proper phase and balance, without phasing dips at the crossover frequency. With the Radax, you have a coaxial two-way system that assures clean, sparkling, wide-range reproduction.
