SPL-Ultra User’s Manual
P r e p a r e f o r I n s t a l l a t i o n
Your new Velodyne subwoofer provides for a number of installation options. Read all of 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.
P l a c e m e n t
The first step in installing your new SPL-Ultra sub 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 the best
output from your subwoofer, try placing it within a foot of a corner. This location will offer the
greatest output levels and maximize 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 feed each subwoofer with one
channel and 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 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
result in damage to the insulation or wire.
Although the Velodyne SPL-1000 Ultra and the SPL-1200 Ultra are magnetically shielded, the
SPL-800 Ultra subwoofer is NOT magnetically shielded. Should you find it necessary to use it
with an older CRT monitor or TV, keep it at least two feet from the monitor. Experiment for
correct distance by minimizing distortion of the picture and colors.
