The Mission 770 loudspeaker was a ground breaker way back in the 1970s when most loudspeakers had paper or – at best – Bextrene cones. Think heavy, coloured sound – ponderous too. Then Mission appeared with their first product, the 770. Sporting a translucent drive unit pressed from polypropylene, it looked good and sounded good. Using the very latest computer design techniques and measuring equipment – explained to me by designer Peter Comeau – this update aims to be even more accurate and revealing than the original.
