Model SB-800 Powered Subwoofer
Placement and Operation
Generally speaking, the best location for your new subwoofer is the
front of the room, close to a corner (Figure 5). Every room has its own
unique sound characteristics, and flexibility in the exact placement of
the subwoofer is always desirable. The closer the subwoofer is placed to
a wall and especially a corner, the more and deeper the bass response
you will hear. However, in some rooms, corner placement can produce a
“one note” boomy effect. Under such circumstances the subwoofer may
work better away from the corner. Experiment to find the best position
in your room.

Using the Subwoofer Low-Pass Control
NOTE: Set this control to "Bypass" if you are using
a receiver that has its own subwoofer crossover.
Set this control to "Normal" if your electronics do
not have a bass management function. The goal
is to optimize the performance of the system by
ensuring that the subwoofer and satellites produce
a cohesive and well integrated sound “picture.”
Most surround sound receivers and processors offer a choice of cross-
overs, typically between 60 Hz and 150 Hz. We recommend using the
100Hz setting when using small speakers such as those in the FS-7.0.
Consult your electronics owner's manual for more details.
It’s generally undesirable to have the main speakers and the subwoofer
overlap too much. Larger speakers means a lower Low-pass crossover
frequency, smaller speakers means a higher Low-pass crossover fre-
quency. Consult the manufacturer’s specified low frequency response
for your main speakers to determine the appropriate Low-pass setting
on your subwoofer. In the end, however, a little time spent experimenting
will generally result in dramatically better bass response.
Care of Your Subwoofer
Your subwoofer is constructed from 5/8” Medium Density Fiberboard.
MDF is a non-resonant material ideal for speaker system enclosures. To
clean the cabinet you may use a soft cloth either dry or slightly dampened
with clean water. Be careful not to wet the cabinet or allow any water to
enter the cabinet seams. Avoid placing your speakers in direct sunlight or
near a source of heat that may, over time, damage the finish.
