Prepare for Installation
Your new Velodyne subwoofer provides for a number of installation options. Read all the
installation information below in order to determine which installation option is best for your
system. Remember to perform all installation procedures with system power turned off to
prevent possible damage.
Placement
The first step in installing your new VMS is to determine where it will be placed in the room.
Unpack the system carefully and use the following guidelines in order to find the best
room placement option.
True subwoofers operate at extremely low frequencies which are primarily 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. To obtain optimum
output from your subwoofer, place it within a foot of a corner. This location will offer the greatest
output levels and optimum low frequency extension. If at all possible, your subwoofer should be
placed along a wall. 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 near the satellite of the
same channel.
Depending on the size and type of furnishings in the room, perfect placement may not be
possible. Finding the best location within your environment will likely require some
experimentation. We suggest you experiment with the location during setup to find what sounds
best to you when seated in your typical listening position.
Regardless of where you install your Velodyne subwoofer, it must remain in an upright position
(woofer facing forward). Using, shipping or storing the subwoofer in any other position for an
extended period of time may result in damage to the unit not covered by warranty.
Caution!
This subwoofer has electronics built into the cabinet. Do not place the cabinet next to
sources of heat such as furnace registers, radiators, etc. Do not place the unit near sour
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 result in damaging the insulation or wire.
