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.

Infinity Quantum Jr


Infinity Quantum Jr
The Monitor JR. speaker by Infinity was called "our Little concert hall" because of its phenomenal realism. And there was standing room, only because of its tremendous popularity.
We've replaced it. With an aven more advanced speaker of the same size and about the same price. Its name is Quantum Jr.
You see, Infinity has improved on the  previous best-seller by incorporating the superlative EMIT Tweeter, first used in our top-of-the-industry Quantum Line Source. A further improvement is a new woofer that combines excellent transient response, deep bass range, and high power-output capacity. The result sounds more than ever like the live performance.
Now you cann have true audiophile musical reproduction from a three-way speaker in a small enclosure, at a price that represents exceptional value.
