Prepare for Installation
Your new Velodyne subwoofer provides for a number of installation
options. Read all the installation information below in order to deter-
mine which installation option is best for your system. Remember
to perform all installation procedures with system power turned
off to prevent possible damage.
Placement
True subwoofers operate at extremely low frequencies that are pri-
marily omni-directional. Keep in mind that frequency response and
output level can be drastically influenced by placement, depending
on the acoustic properties of the listening room. Typically, the opti-
mum location for a subwoofer is tucked away in a corner of your
listening room. This location will usually offer the greatest output
levels and optimum low frequency extension. The worst location for
a subwoofer is typically far away from any walls, and close to the
center of your room. Avoid these locations when possible. When
using a pair of Velodyne subwoofers in stereo, it is preferable to
place each subwoofer by the satellite of the same channel.
Caution! This subwoofer has electronics built into the cabinet.
Do not place the cabinet next to sources of heat such as fur-
nace registers, radiators, etc., or near sources of excessive
moisture, such as evaporative coolers, humidifiers, etc. The
power cord should be routed in such a way that it will not be
walked on, pinched, or compressed in any way that could re-
sult in damaging the insulation or wire.
Regardless of where you install your Velodyne subwoofer, it must
remain in an upright position (woofer facing forward). Using, shipping,
or otherwise storing the subwoofer in any other position for an
extended period of time may result in damage to the unit not covered
by warranty.
Your VRP subwoofer is magnetically shielded to reduce the amount
of stray magnetic energy emitted from the speaker’s motor structure.
This greatly increases flexibility when placing the unit close to video
