Setup
The configuration and placement of your M3-8 monitors on speaker stands or your desktop
workstation may affect the performance of the speakers. Use the following tips to achieve the
best performance out of your M3-8 monitors:
Speaker Placement
Place the M3-8 monitors so that the two speakers
and the engineer form an equilateral triangle when
viewed from above. Angle the speakers slightly
inward so that all three drivers face the engineer.
In general, it is recommended that M3-8 monitors
be placed at least one foot away from the nearest
wall, ceiling, or any other large, flat surface (the
reason for this is covered in detail in the following
chapter of this guide). If practical considerations
such as limited studio space make this impossible,
M3-8 monitors include three separate equalizer
controls to compensate for placement near walls
and corners, as well as to compensate for the
general acoustic response of your monitoring
environment.
Speaker Height
Position the speakers so that they are parallel to
the ground and that your ears are between the
midpoint of the woofer and the midrange
driver/tweeter.
Speaker Orientation
If possible, place the M3-8 monitors in their upright position and avoid laying the speakers on
their sides. The M3-8 woofer and midrange driver/tweeter are vertically aligned and will provide
the best performance when the speakers are placed upright. Placing them on their sides may
create strong reflections from nearby surfaces resulting in spectrally unbalanced sound.
If your M3-8 monitors must be oriented horizontally due to space or line-of-sight considerations,
place the speakers so that their midrange driver/tweeter is on the "inside" to improve imaging.
