Fisher 55

Nothing definite is documented about a Fisher model with the simple designation "55." The name does not appear in period price lists, service manuals, or the usual equipment directories. It may be a shorthand or orphaned reference to the Fisher XP-55, a compact bookshelf loudspeaker that Fisher advertised heavily in 1967. A review in High-Fidelity (September 1967, p.78) noted the XP-55's fairly high efficiency for a small air-suspension design. It rated the speaker for 10-30 watt amplifiers, with usable bass to about 65 Hz.

No surviving documentation confirms that "Fisher 55" was ever a distinct model, whether a tuner, an amplifier or some other component. Until a period source or an original unit turns up, treat it as unverified.
