Positioning Stereo Loudspeakers
Opus² M1 and M2
The M1 and M2 are designed for stand mounting. The
Opus Stand has been specifically designed to optimise their
performance. As an alternative the M1 and M2 may be
wall mounted on rigid brackets or placed on rigid shelves.
Ideally the top of the speaker should be at ear level to a
seated listener. If the rear panels of the speakers are placed
close to the walls the amount of bass will be increased but
the clarity may well suffer - you should experiment until you
get the best result.
The distance between the speakers should be the
same as between you and the speakers.
The table below shows the ideal
distance your model should be
from the wall

Opus² Subwoofers:
If the loudspeakers are placed too close to the walls the bass will increase but may be boomy and indistinct. If the loudspeakers are
placed further away from the walls, the inward angle ("toe in") may be increased by up to 40%, although this may restrict the width
of the optimum listening position. As personal taste plays a large role, experiment with different configurations and play a wide
range of programme before finalising the position of your speakers.
