Surround Sound System
One signal source for the ButtKicker
®
is the “Subwoofer”
output of your surround receiver/processor. This output
is controlled by the master volume control and usually
a separate subwoofer control. If a subwoofer is also a
part of the sound system and connected to this signal
output, then a “Y” cable may be used to split the signal
two ways (Figure 3-C).
Gaming Consoles/Stereo System
The ButtKicker also works well in a two channel, stereo
system and with gaming consoles like Microsoft’s XBOX
®
,
Sony’s PlayStation
®
2 and Nintendo’s GameCube™. In
a two channel stereo system, the low frequency signals
are very seldom only on the left or right channel, so a
connection to either left or right channel preamp output
would produce satisfying results (Figure 3-B).
A further note about gaming consoles:
The XBOX
®
, PlayStation
®
2 and GameCube™ all have
digital out capabilities that enable the console to connect
to a surround sound (5.1, 6.1, etc.) system. Many new
games feature 5.1 digital sound with a .1 or LFE track
that is ideal for use with the ButtKicker. If you connect
your gaming console to a surround sound processor
then the ButtKicker will connect to the system using
your processor’s “subwoofer out” as described in the
preceding “Surround Sound System” section.

Mounting Consider
ations
Example one
A room with a suspended, joist ß oor measuring 12’ by
14’. The ß oor is only supported around the edges (at
the walls) by a foundation, and is capable of bending
and vibrating in the area between its supported hard
points. This is similar to a guitar string that can vibrate
between its supporting hard points at each end of the
string. This ß oor would be best shaken by a ButtKicker
®
mounted to the ß oor in the center area of the room
away from the dampening action of the walls.
Example two
A room, similar in size to the room of Example one,
but this construction is different in that the ß oor has
additional support underneath, made up of a pier or
foundational wall that runs under the ß oor about 5 feet
from one of the room’s walls. The ß oor is now supported
at an additional point, which effectively divides the ß oor
into two suspended sections measuring 12’ by 5’, and
12’ by 9’. This effect would be similar to placing a Þ nger
on a guitar string, holding the string against a fret.
This ß oor will vibrate in a different manner than that
of Example one. The 12’ by 5’ section will not allow
as much bending of the ß oor’s materials between its
supports (hard points) and will therefore exhibit less
low frequency shaking than the 12’ by 9’ section. (For
example, a higher note on a guitar string.)
As an additional note, if the wider section of this
ß oor were shaken with the ButtKicker, the narrower
section would still exhibit some “sympathetic” and less
pronounced vibrations because of its connection to the
wider section of the ß oor.
Example three
A room with a concrete slab ß oor, lying directly on
the earth. This ß oor will be practically impossible to
shake. In your main listening area, your favorite couch
is the best option. The feet at the ends of the couch are
pressed and held Þ rm against the concrete slab by its
weight and are therefore unmoving hard points of the
couch. The horizontal length of the couch between the
feet is suspended and will bend and shake but only to the
degree allowed by its materials and construction. See the
“chairs and couches” section for more information.
