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 Fisher XP-55 speakers

Compact Free-Piston Speaker System
Though it measures only 20" by 10" by 9" deep, the Fisher XP-55 incorporates a bass speaker that is very close to that of large speakers and at the same time free of artificial correctives like shaping networks that after the bass output of the amplifier.
This is an 8-inch unit with a magnet structure weighing 3 pounds, a flux density of 12,500 gauss and a totally new suspension system utilizing a long-throw jnverted half-roll surround. Free-air resonance is 33 Hz, an almost incredible figure for an 8" driver. The 2-1/2 inch tweeter has a new low-mass cone made of a combination of the usual fibrous materials resulting in peak-free response out to 19,000 Hz without coloration.
The completely enclosed baffle is heavily damped with Acoustiglas packing. The result is fundamental bass response down to 37 Hz, without doubling.
