B-I-C  Venturi Speaker Systems

In the short time that B-I-C Venturi speakers have been available to the public, they have earned an unprecedented reputation for reproducing accurate,life-like sound.

Based on an eclusive physic principle and coupled with some of the most advanced engineering ever concentrated on a speaker system. B-I-C Venturi speakers represent the ultimate in the state of the art.. This, plus their remarkably high efficiency and power handling capability, make it possible to finally achieve the wide dynamic range of music not previously available to the enthusiast.

 B-I-C Venturi  Formula 4

The Formula 4 is capable of producing still lower bass response even more efficiently than the remarkable Formula 2. it employs a larger, but still modest-sized enclosure and a 10" woofer.

The Formula 4 will yield sound pressure levels from amplifiers rated as low as 15 watts RMS that enhance such hi-fi systems and produce remarkable accuracy and quality.

Yet, when operated with amplifiers capable of very high, clean output power, the Formula 4 really shows its mettle. Played softly every musical nuances and delicate modulation is heard with absolute clarity and definition. Played loudly, the Formula 4 performs cleanly and articulately, following step for step the total dynamic range of the original program.

 B-I-C Venturi Principle Bass Section - transforms the magnitude of air mass and energy in a way never before applied to acoustics. The result is bass response hundreds percent more efficient and substantially purer in quality than is possible from any other speaker of comparable size.

Biconex Pyramidal Dispersion Horn - was developed to match the demanding capabilities of the B-I-C Venturi  bass section. It is far more efficient, can handle more power and covers a wider, uninterrupted frequency range than cones and domes. And, unlike other horn designs, it can't add metallic sound coloration and has truly wide angle disperdion in both the horizontal and vertical planes, for unrestricted system positioning.

Dynamic Tonal Balance Compensation - adjusts speaker performance automatically (when desired) to provide aurally "flat" response at all listening levels in accordance with the Fletcher-Munsen hearing characteristics. This is accomplished in a manner which cannot be achieved by amplifier loudness or contour controls.

Extended Musical Dynamic Range - results from the unique combination of high efficiency and high-power handling capability. Even our smallest model, the new Formula 4 can be used with amplifiers rated up to 100 watts RMS per channel.

Sturdily constructed enclosures, choice of 6 grille colors. The enclosures are sturdily constructed and are free of resonances and other spurious vibrations which add unnatural coloration often mistaken as bass. A new type, sonically transparent, attractive foam grille is available in a choice of black, brown, beige, burnt orange, blue, red, any of which can be resprayed to any desired colors. Optional bases available to enhance the appearance of B-I-C Venturi  speakers when placed on the floor.
