Bozak B-310A (circa 1955–1962+)
The B-310A was Bozak's largest speaker system. According to a 1960 report in High Fidelity (September 1960, p.18), it had been introduced five years earlier and was already regarded by music connoisseurs as "the ultimate in fine speaker systems." It stayed in production at least through 1962, when High Fidelity (September 1962, p.70) gave it a full technical review.
The system is a three-way design with a total of fourteen drivers: four 12-inch woofers, two 8-inch midrange cones, and eight cone tweeters. The tweeter diaphragms are made of a then-new "metallicized plastic." A frequency-dividing network handles the crossover points. High Fidelity (September 1962, p.71) measured them at 400 Hz and 2,500 Hz, and noted the system showed no harshness or ringing at those transitions. The enclosure is an infinite-baffle design, described as rock-solid and beautifully finished. It measures 53 inches high, 36 inches wide, and 19 inches deep. The listed price in 1962 was $770.
Reviewers found the B-310A neutral and impartial across all types of program material. Human voices sounded human, and no instrument was favored over another. The same High Fidelity test noted that the system could work with medium-powered amplifiers, but the deepest bass might lack some "sock" and "bite" unless a more capable amplifier drove it.
Bozak's own advertising (reported in Audio, July 1959, p.45) said the B-310A used the same basic driver units and enclosure philosophy as the rest of the Bozak line, just more of them. The difference, it said, was one of scale, not of fundamental quality.
Little is documented beyond the review data. Production totals, finish options, and the exact years the B-310A was offered are all unknown. It appears to have been a flagship model, positioned above the B-400 and the compact "Spinet" series.
