The Mission 770 Freedom was an award winning British loudspeaker produced by Mission Electronics, an audio company based in Huntingdon, United Kingdom. The Freedom model variants date from the late 70s through to the late 80s. more...
In all of its incarnations it was a large stand (or rather 'pedestal') mounted loudspeaker of a two-way design, combining a 200-millimetre (7.9 in) woofer and 25-millimetre (0.98 in) tweeter in a reflex tuned cabinet.
The speaker's unique selling points were its innovative design, natural sound quality and extremely high power handling for a consumer (as opposed to a professional) system. Mission was the first company to negotiate the patent rights for the commercial exploitation of polypropylene as a loudspeaker cone material and the speaker system as a whole was able to handle what HiFi Choice magazine regarded as an "extraordinary" amount of power.
Mission 770 (circa 1978)
Mission 770II (circa 1980)
The original Mission 770 was very well received by press and public alike (e.g. What HiFi ). The updated 'Mark II' version aimed to build on this success in the face of increasing competition and the growing popularity of home hi-fi in general.
The most significant change heralded by the Mark II model was the incorporation of a new mid/bass driver, which still used the innovative (and transparent) polypropylene diaphragm material, but employed an enlarged voice coil of 33 millimetres (1.3 in). Thermal performance, and by implication power handling, increased, along with a reduction in some previously noted distortion.
