Fisher 55-B (circa 1968)
Little is documented about the Fisher 55-B under that exact name. What the Archive's period files do contain turns up under the fuller designation Fisher XP-55B - a two-way acoustic-suspension loudspeaker that Fisher advertised throughout mid-1968. Whether the 55-B of this catalog is the same product as the XP-55B, or a closely related variant, the surviving evidence doesn't say outright. The ads are the record.
Fisher's own advertising in High Fidelity (June 1968, p.3) made a point of the XP-55B's natural reproduction. The ad called the speaker "an engineering marvel" and claimed it covered 37 Hz to 20,000 Hz without doubling, with tight, solid bass, smooth midrange, and clean treble. A follow-up ad in the same issue teased "what's even better than the new Fisher XP-55B speaker?" The answer was a matching second one. Later that year, High Fidelity (September 1968, p.2) carried Fisher's assurance that the speakers were "the 2-way Fisher XP-55B acoustic-suspension systems we sell separately for $99.95 the pair."
That is all the period record offers. No service manual, no independent bench test, no production or sales history, and no specification sheet attributable specifically to the 55-B name has surfaced in the Archive's holdings.
