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.

Kettle Drum Speaker of Bozak B-201 (1950)

The distinctive hemispherical shell of the Bozak Kettle Drum Speaker is not just an attractive enclosure, not just a rigid baffle, but an integral, functioning part of new concept in sound reproduction. Actual comparative tests are substantiated by critical listening in proving that the acoustically treated Kettle Drum baffle is unsurpassed in tonal realism and listening ease.

Unlike conventional enclosures, the Kettle Drum does not have a sharply peaked cavity resonance. Thus, all types of sound, instrumental an vocal, are heard without muffling or other distortion. Only a hemispherical baffle is devoid of standing waves. Only the Bozak Kettle Drum employs a hemispherical "tympani" baffle.


True Pitch, True Tympan Bass

Distinctly Natural Treble

Exceptionally Low Resonance

Outstanding Transient Response

Attractive, self-contained Enclosure (32" dia. spun steel acustically treated baffle with lifting handle, circular panel and tripod base)

Matched Bozak Team Recreates Audio Spectrum

From one end of the useful audio spectrum to the other, from the plucked string of a bass viol to the uppermost coloratura tones, only true, undistotred pitch is reproduced by the Kettle Drum. The 12-inch Bozak woofer, noted for its robust, life-like bass, and the Bozak dual tweeter, distinguished for its non-piercing highs, combine in the "tympani" shell to offer a tonal depth and balanced roudness that is best described as a "3-dimensional" effect.

Effective Crossover Built In, No Extra Network Needed

Response characteristics of the specially damped woofer and dual tweter are such taht an elaborate crossover filter is unnecessary. A built-in 4 mfd. condenser, used in series with the tweeter comprises the crossover network. This simplification is made possible beacuse identical velocities of propagation of both highs and lows permit no annoying phase distortion.

Let Tour Ear Compare

For all applications demanding highest quality sound reproduction at moderate power levels, try the speaker that makes you feel "you are there" - Bozak Kettle Drum, Model B-201.
