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-250A speakers


 Bozak proudly presents the LS-250A, Bozak's smallest speaker three-way speaker system but a giant in performance.

 Designed especially for those demanding superb sound but with limited listening room space, the LS-250A offers more quality for its size than any other speaker system in its price class. Bozak's soft dome, wide frequency tweeter provides 180° dispersion throughout the listening area, producing minimal distortion and outstanding transient response in the upper register. The LS-250A's 4" aluminium cone is carefully engineered and designed to produce unusual clarity and exceptional capabilities in the midrange frequencies.

 As the sounding board is the heart of the piano, the bass driver is truly the heart of the loudspeaker system. Originated at Bozak over thirty years ago, the 12" variable density bass cone used in the LS-250A speaker is compounded of formula. This unique structure gives the cone low mass-thus low inertia. The warm, rich bass sound of the LS-250A, with its sense of feel and ease for effortless sound replication, is a Bozak trade mark recognized throughout the U.S. and around the world.

 Also featured in the LS-250A is a three-position contour switch which permits the selection of bright, normal or mellow sound characteristics to match the listening room acoustics or listener preference.

 The cabinet housing the LS-250A components is rigidly constructed of 5/8" flake board, and totally sealed (infinite baffle type). Outer cabinet surfaces of the LS-250A are of walnut-grained vinyl, and the interior of the enclosure is heavily damped to minimize cabinet reflections.

The Bozak LS-250A, representing state-of-the-art. Engineering and design, is guaranteed to provide the listener with years of superb sonic performance.
