Altec 908 8B (1965)
Documentation on the Altec 908 8B is thin, and even its exact designation is uncertain. The single index-style source that records this model lists the unit as the "Altec 908-8A Duplex" within a section headed "Altec 908-8B". It could be a typo, an alternate naming convention, or two distinct variants. Nobody has resolved it.
What the record does show is a 12-inch, 2-way bass reflex speaker from 1965, with the "Duplex" name that Altec used for its coaxial driver designs. The source table gives a frequency response of 50-15,000 Hz, an 8 Ω impedance, and a sensitivity of 91 dB. Crossover points are listed at 1500 Hz and 3500 Hz, with a built-in 2-way crossover. The woofer diaphragm is aluminum. The cabinet is rear-ported, came in Walnut or Oiled Walnut finishes, and measures 13.98 × 23.86 × 12.28 inches (H × W × D). The listed weight is 20.55 lb. The same source also contains a conflicting figure of 23.86 lb, likely a data-entry artifact, but unconfirmed.
Nominal power is rated at 25 watts. The maximum power figure conflicts within the source itself, showing both 80 watts and 60W, so no single value can be stated with confidence. No original price and no market context have surfaced. Period trade coverage from Sound and Communication does mention Altec speaker systems in professional sound installations of the late 1980s.
