The 70 is designed
wiat an unusual cabinet construction. The drive units are mounted on Mission
rigid particle baffle board while the carcass consists of a sandwich
construction to distribute and dampen enclosure resonances. Carefully optimised
drive units ensure the smooth bass performance essential in high quality
system. The driver geometry is inverted in Mission's novel style. This combines
with elegantly simple crossover networks to enhance phase coherence and produce
an astonishing three - dimensional stereo stage.
Technically the
frequency response is unusually smooth and well balanced. Whereas the
competition has an irregular response often as poor ±5 dB the 70 measures flat
to within ±2 dB. When measured off axis it exhibits no mid-band cancellations.
The modulus of impedance is very smooth, remaining above 6 Ω and with minimal
electrical phase angles.
The ensures that the
speaker presents an easy load to amplifiers. Harmonic distortions are minimised
even at low frequencies, and sensitivity high sound pressure levels even with
modest amplifiers.
