Placement of the Beosound Bollard speakers throughout the home’s exterior will depend on
a couple of factors. The first is how uniform of a sound field is required. The laws of physics
dictate that the further the listener is from the sound source the lower the apparent sound
pressure level or “volume.” Because of this, there will always be areas with less sound and
others with more. A greater number of speakers in the system will always make for more
even coverage. The second factor is the desired maximum sound pressure required. Some
systems are designed for background or ambient music only, while others are designed
to rock the house or provide dance music. Again, the number of speakers will affect the
maximum output. Consider creating different zones where louder music is required in one
area and softer music in others.
The Beosound Bollard also has two dispersion options. One is omnidirectional allowing
sound to projected 360 degrees from the enclosure. The second is accomplished with an
insert to limit the sound to half if the dispersion or 180 degrees from the enclosure. This
is perfect for border areas where you are concerned about unwanted sound spilling into
a neighbor’s yard or an area where the music is simply unwanted. The Bollard must be
ordered in one of the two configurations as the insert must be installed at the factory.
Changing the insert in the field is not an option as doing so would likely damage the unit.
If you are concerned about determining speaker placement, Origin Acoustics offers a free
design service to help you map the optimal speaker placements as well as recommended
amplifier power and project scale.

Once coverage and sound pressure requirements have been determined the Bollard
locations can be selected. Before digging, confirm there are no subterranean obstructions
such as water or gas lines, sprinkler pipes or electrical conduits. Holes for the subs should be
deep enough to cover the entire lower section of the enclosure with approximately 1-inch
of dirt on top of the that section. This will allow the pillar (shell) to protrude about 18-inches
above the surface.
