Two Way Loudspeaker System (1983-85)
The Mission 70 is an extraordinary state of the art product.
The design objective was to manufacture the most compact loudspeaker system which was nevertheless capable of reproducing the extremities of the audible frequency range. This resulted in a true hi-fidelity speaker system capable of handling musical materials with exceptional dynamic range, including digital master tapes, and remaining linear at all listening levels.
Here we should point out that many loudspeakers can only create the excitement and dynamics of music when played at loud levels. In fact, it is a tragedy for the consumer that most Hi-Fi systems sound no better than a transistor radio when played at low levels. Indeed, this is why cheap amplifiers offer a loudness control to artificially compensate for these inherent weaknesses, and it requires dedicated manufacturers to avoid such complex pitfalls.
The 70 is manufactured of sandwiched construction to dampen and distribute enclosure resonances and uses sculptured MDF for the baffle board. The bass unit is a high quality Mission product with a unique cone design and a quality 19mm ferrofluid damped dome tweeter.
The filter is a full multi-component design incorporating Mission's own electrolytic capacitors and low saturation inductors. The driver geometry is inverted in the novel Mission style resulting in superb three dimensional stereo stage. The total design is carefully integrated to result in a wide bandwidth system free of unwanted resonances, distortions, frequency response anomalies and colourations.
The 70s are recommended for use on bookshelves or stands and with amplifiers ranging from 20W to 75W per channel.

I spent some time with these speakers in the 1980's, and I was impressed with their neutrality and lack of hype. The frequency response was quite flat without any particular part of the spectrum calling attention to itself. The top octave was a little reticent, and the distortion was only average. The dynamic range was good for such a small speaker but not great. The woofer's excursion was a bit limited for anything over 95 db or so. Subwoofers work wonders with this pair. I'd say the lower frequency limit was in the 70-odd hertz region. At the price, it is most definitely a 'best buy' type of bargain because it is so honest and free from colorations. I like the understated appearance very much, though the light weight suggests thin-walled cabinets. I highly recommend this speaker given its usually low price.
