These systems were based on a discovery by Italian physicist Giovanni Battista Venturi (1746-1822), who first observed that when air (or any other fluid) is forced through a constriction, its velocity increases and its pressure decreases. The Venturis' enclosures appeared to be conventional vented boxes, but their ports were strongly flared both inside and out and frequently turned a 90° bend inside the box. The manufacturer proudly pointed out the output from the Venturi port had higher pressure and lower distortion than the output of the cone driver itself. BIC is an American company that imported components from England and Japan to the United States. In the 1960s BIC handled such well known brands as Wharfedale, Garrard, and Luxman. In the 1970s it began producing components and speakers under its own name, including the first belt-driven record changer, a two-speed cassette deck, and speakers using the patented Venturi design. Back view of BIC V-604 shows the rear-mounted woofer and tweeter, two ports (one plugged), and the terminal cup. If you were old enough in the mid- to late '70s to be interested in hi-fi, you probably remember BIC's heavy pro motion of its Venturi speakers. These properties are common to most vented boxes, not just BIC's; what BIC accomplished was the design and manufacture of a well-engineered vented-box speaker with a low-turbulence vent, which was not very common in those days. The V-604 is the larger of two bipolar floor-standing tower speakers that have Venturi vents. Both are two-way designs with front and rear drivers that operate in phase with each other. The V-604 has 6 inch woofers and 3/4-inch dome tweeters, one each on the front and on the rear, with the tweeters located above the woofers.
