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
True subwoofers operate at extremely low frequencies which are primarily
omni-directional. While it is recommended that the subwoofer be placed
on the same plane as the satellite speakers, room and system conditions
often dictate otherwise. 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 optimum 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.
