Loudspeaker System (1989)
Mission's flagship system, the 767, is a unique exercise in balancing the benefits of a large, truly dynamic speaker with the attributes of physically smaller systems.
To yield bass extension down to 20Hz, Mission has produced a tall and elegant column made from 25mm medium density fibre board damped on all surfaces with visco-elastic material and braced at specific points to eliminate resonances.
Fitted to this are two 8.25 inch bass drivers handling the bottom two octaves of the frequency range. To ensure that these drivers perform optimally, the 767s are supplied with a Cyrus Two based stereo amplifier. This incorporates a phase and amplitude alignment section which actively integrates the low frequency units with the 7 inch midrange units, extending the bass response flat to 20Hz.
The midrange units together with a super elliptical impedance transformed high frequency unit cover the range 80Hz to 20KHz, leaving the low frequency units to reproduce only the deepest notes.
The crossover arrangement and controls for adjusting the amplitude and roll-off points of the low frequency signal allow the 767 to be fine tuned to both the room and the partnering equipment.
Configured to be used in bi-wired or bi-amplified mode if required, the 767 is a true high-end system capable of yielding the most lifelike sound reproduction imaginable from a domestically acceptable enclosure.
