Explore Bozak vintage audio equipment in the Vintage Technology Archive.

Mixers

• AR-4 — Bozak AR-4 rotary mixer revives 1970s CMA-10 circuitry in a modern 4-channel desktop format, priced at $2,140 — a niche tool for analog purists.
• CMA-10 (1970s) — Bozak CMA-10 professional stereo mixer/preamplifier from the 1970s. Little documented; known from 1972 announcement and 1984 directory listing at $499.

Speakers

• 14 — Bozak 14 — no documented information survives for this model in period catalogs, reviews, or advertising. A gap in an otherwise well-recorded speaker lineup.
• 30 — Bozak Model 30 audio component. Little is documented; period references to the B-305 series exist but confirmed specs for the Model 30 are not recorded.
• 31 — Bozak 31 loudspeaker. Almost nothing is documented about this model in period sources. No specs, review, or catalog listing has been located.
• 4000A — Bozak 4000A — barely documented; appears in the research file as a Bozak speaker, possibly the truncated 1976 High Fidelity listing at $514.
• B-1000 — Little is documented about the Bozak B-1000. The closest known variant is the B-1000A (The Bard), a sealed-enclosure weatherproof outdoor speaker listed in High Fidelity (1976).
• B-199A — Bozak B-199A 12-inch wool-cone woofer, 40-4,500 Hz, 8 or 16 ohm — the bass foundation of Bozak's building-block speaker systems.
• B-200Y — Bozak B-200Y — a 2-inch aluminum-dome tweeter with foam-rubber damping, built into nearly every Bozak speaker from bookshelf to Concert Grand.
• B-209B — Bozak B-209B midrange driver — 8-ohm component of Bozak's modular speaker systems, sold as an upgrade path to three-way.

• B-302 — Bozak B-302A (1957–1971) 3-way speaker: 40Hz–20kHz, 8Ω, 50W. Legendary sealed-floor design with coaxial bass/tweeter and aluminum-sandwich midrange.

• B-305 — Bozak B-305 — two-woofer, three-way infinite-baffle speaker, 35–16,000 cycles at 16 ohms, 30 watts, $390 in 1956. A mid-century American classic.
• B-310 — Almost nothing is documented about the Bozak B-310. Only direct trace: a 1954 High Fidelity letter. Later B-310A and B-310B models are separately documented.

• B-400 — Bozak B-400 vintage speaker system: 14 drivers, 28-16,000 cycles, 8 ohms, 50-60W, per late-1950s Bozak advertising. With when it was made.
• B310B — Bozak B310B Concert Grand loudspeaker system, 1970-1971, slot-loaded tweeter array, 36-inch wide by 52-inch tall, $897.00. Little-documented flagship model.
• B410 — Little is documented about the Bozak B410. The model shows up in a couple of period equipment directories.
• CMA-2-80 — Documentation on the Bozak CMA-2-80 is thin — the archive record currently consists of two period sightings and little else.
