Home Theater Installations
Home Theater installations are typically
medium sized living rooms or game rooms
that have large, flat walls. Acoustics in this
type of installation can have a big effect on
the SPL (Sound Pressure Level) and f3 (low
frequency cut-off) of the subwoofer because
the walls are very reflective. The only ele-
ments in these installations that acoustically
“absorb” sounds are furniture and carpet.
Dramatic “Boundary Loading” can be
achieved by locating the subwoofer under a
table, next to a wall or in a corner (FIG. 4),
thus increasing SPL and lowering the f3 of the
subwoofer system. Locating the subwoofer in
the middle of the room or in a large open
area where there are few reflective surfaces
will cause a decrease in SPL and an increase
in f3 and standing waves. Experiment with
different locations in the room to determine which type of bass response works best in your home the-
ater. Example; place the subwoofer in the listening area, listen to the subwoofer while standing in dif-
ferent locations in the room. Locations that you hear the most accurate and smoothest bass response
would be a good location to place the subwoofer.

Location
The size of the room used for your Home Theater can have a significant effect on the bass response of
your system. Since many movies exaggerate explosions, earthquakes, and other low frequency effects,
a high performance subwoofer system is required. Your Fosgate Audionics subwoofer is specially
designed for these high levels of excursion and linearity. In order to get the most out of your sub-
woofer, Fosgate Audionics has documented the differences between typical Studio and Home Theater
installations.
