B-I-C VENTURI speakers (advertisement, Aug. 1975)

These four major developments make the BIC VENTURI speakers totally unlike all others... and better.

BIC VENTURI Principle Bass Section (pat. pend. ) transforms the magnitude of air mass and energy in a way never before applied to acoustics. (Fig. A) 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 (pat. pend. ) was developed to match the demanding capabilities of the BIC 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 dispersion in both the horizontal and vertical planes, for unrestricted system positioning.


B. Shows output of low frequency driver when driven at a freq. of 22 Hz. Sound pressure reading, 90 dB. Note poor waveform.

C. Output of BIC VENTURI coupled duct, (under the same conditions as Fig. B) Sound pressure reading 111.5 dB (140 times more output than Fig. B) Note non-distorted appearance.

Dynamic Tonal Balance Compensation (pat. pend. ) 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 1 can be used with amplifiers rated up to 50 watts RMS per channel. The Formula 2 will handle 75 watts; the Formula 4, 100 watts; the Formula 6 can take 125 watts. Yet any of these can make Titans of low-powered amplifiers.

A 4-page color brochure is needed, at the very least, to properly describe what makes these BIC VENTURI speaker systems so different, and we think you'll agree, better. So this is what we will send you, upon request. Or better still, visit your BIC VENTURI dealer, and hear for yourself.
