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 LS-220A speakers

With its distinctive" tower-like" appearance, the LS-220A, a two-way speaker system, has been designed to provide "bigspeaker" response from its relatively small, columnar enclosure. The tower concept provides the listener with an exciting vertical image sound field with a total absence of the beaming effect usually found in small speaker systems.

Its robust bass, produced by Bozak's 8" aluminum woofer, is integrated with a specially designed cross-over network that assures a smooth transition to the celebrated Bozak 1" soft dome tweeter which provides clean clear highs without a hint of sibilance.

Bozak speakers have always been designed so that they do not "intrude" between the music and the listener.

The LS-220A's 8" aluminum woofer has a rigid, low mass, high compliance cone, and this together with other design criteria, permits the use of modestly powered amplifiers (25 watts RMS) with these efficient speakers.

The clarity, smoothness and warmth of the Bozak treble, without the annoying shrillness heard in many competitive tweeters, assures many hours of continuous listening pleasure with a total absence of "listener Fatigue", due primarily to uneven frequency response.

The sonic performance of the LS-220A assures that this strikingly handsome speaker system will be a worthy new addition to the Bozak product line.
