placement behind a mixing console
In this illustration, the M2 is elevated
20 inches and the recommended
distance between the speaker and a
seated listener is 92 inches or greater.
When a speaker is elevated, the
distance of the high frequency driver
to the listener may be greater than
the distance of the low frequency
driver to the listener. Observing the
recommended minimum listening
distance optimizes loudspeaker
coverage at the listening position.

This table provides minimum listening distance
recommendations for a seated listener when the
speaker is elevated. As an example, when the speaker
is elevated 20 inches above the floor, a seated listener
should be 92 inches or greater from the speaker.

When installing M2 speakers behind a mixing
console, the speakers should be elevated so the
console does not impede speaker performance.
Ideally, a line drawn from the center of the
woofer perpendicular to the M2 enclosure should
clear the top of the console meter bridge. The
illustration below shows M2 installation behind a
professional mixing console. When placed behind
a console with a meter-bridge height of 45”, the
M2 speaker should be elevated 20” off the floor.
- Ensure each M2 is placed on a stable
platform that is capable of bearing the
full weight of the speaker.
- Ensure that the front and sides of the
speaker enclosure are perpendicular to
the platform.
- If the speaker is to be used at an
elevated height or used at an angle other
than perpendicular to the supporting
platform, the speaker should be
professionally installed and restrained to
ensure it will not fall.
- The M2 enclosure is not designed to be
suspended.
- Never drill holes into the M2 enclosure.
CAUTION: Unsafe speaker placement can cause personal injury or damage to the speaker.
