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.

 The Model SPB12 (and SP12) may be used as low-frequency drivers in expanded separate 2 and 3-way systems. In this application, the operation of these units is comparable to the E-V Models 12 W and 12BW LF drivers. Compatible components for use with these drivers are shown on the 'Building-Block Method" Compatibility Chart.
