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 Models LS-250 loudspeakers

Model LS-250 is the second model developed in the Listener Series. It is the smaller three-way system to bear the Bozak name. Somewhat larger than the LS-200 , the LS-250 offers greater power handling capacity., the enhanced bass response associated with larger enclosures and the greater mid-range definition which characterized three-way systems as compared with two-way speakers.

 

The LS-250 embodies the experience and skills developed by Bozak's engineering team after more than "30 years" of designing loudspeakers which have been the standard by which knowledgeable audio engineers and audiophiles alike. Have judged loudspeakers performance.

 

Because of Mr. R.T. Bozak's insistence to strict adherence to the basic laws of physics, so far as current technology would permit, the great majority of Bozak speakers manufactured over the past three decades are still in service. It is rare indeed to find a traded in Bozak.

As technology has advanced, it has become possible to more nearly satisfy the underlying principles of physics in musical production. Model LS-250 represents the current state of the art.. It embodies a combination of frequency, phase and transient response which would have been impossible to achieve a decade ago.

 

The three-way LS-250 system incorporates a newly designed 12-inch bass speaker, a 4-inch midrange driver and Bozak's acclaimed new Z-series treble speakers. A phase-corrected cross-over network smoothly shifts sound from bass to midrange at 800 Hz and from midrange to treble at 2,500 Hz.

A three-position treble switch permits the selection of "Bright"> "Normal" or "Mellow"  sound characteristics to match listening room acoustics.

The cabinet is a rigid 5/8-inch totally sealed enclosure of the "Infinite baffle" type. Exposed surfaces are clad in walnut-grained vinyl of such quality that it is scarcely distinguishable from actual wood. The matching brown cloth grille is removeable for easy access to the front mounted drivers.
