Genelec G • Stencil Tool - Genelec 8010 Setup Manual

A first solution is to flush mount the monitors in a hard wall (creating a very large
baffle) eliminating the rear wall reflections and therefore cancellations.
Another possibility is to place the monitor very close to the wall. This raises the
lowest cancellation frequency so high that the monitor has become forward-
directing, and the cancellation no longer occurs. Remember that the low
frequency boost should be compensated for when the monitor is mounted close
to the wall (up to +6 dB gain).
Alternatively, one could move the monitor considerably far away from the wall:
the cancellation frequency moves below the low frequency cut-off of the monitor.
When the monitor moves away from the walls, it also moves close to the listener.
This increases the direct sound level and reduces the reflected sound level, and
this also improves sound quality.
A different solution is to modify the wall and make it very absorptive so that the
amplitude of the reflected energy is small and does not cancel the direct sound.
When a subwoofer is used to reproduce low frequencies the monitors can be
placed more freely. The subwoofer should be placed close to the wall(s). The
monitors may be placed at distances where low frequency notches do not occur
in their pass-band.

How to draw correct monitor angles with the G • Stencil?
Use an architectural plan of your room. Place the centre of the G • Stencil on
the plan in the selected listening position on an even surface. Attach a pin to
the centre of the stencil to hold it. Draw the reference centreline along the room
symmetry axis. Then draw all other lines at the appropriate angles corresponding
to your monitoring setup.
