Quick Setup
This section is for those who are more experienced with sound
system installation. The ButtKicker
®
is a passive, 4 ohm speaker
load, which requires power from an audio power amplier,
which in turn requires an adequate signal feed from your sound
system (Figure 1). Shaking forces are produced in the direction
of the axis of the shaker as shown (Figure 2). A positive voltage
at the red terminal wire will produce a “push” by the ButtKicker
toward its feet (red terminal is positive). It can be mounted
on the topside of a surface or inverted and mounted to the
bottom side of a surface.
It may also help you to consider the ButtKicker as a “mechanical”
powered subwoofer that enables you to “feel” the low end (bass)
by vibrating the surface to which it is attached as opposed to
moving air like a subwoofer. And, like a powered subwoofer,
the ButtKicker also requires a separate amplier to power it.
While powered subwoofers have their ampliers in the speaker
cabinet, the ButtKicker’s amplier is a separate component
because the ButtKicker is typically mounted in, beneath or
on what it shakes, typically not an appropriate place for
an amplier.

Quick Setup
needed under the riser. As always, keep in mind any
maintenance that may become necessary.
Think “suspension.”
In essence, you’re constructing a oor above the room’s
floor. Build the riser similar to a suspended wood
joist oor to give the riser its greatest low frequency
response.
The major differences between a riser and real oors
are the suspension points and tie points (to other
external structure). The riser should be free oating (not
tied into any adjacent walls), and suspended by short
sides only. Use rubber isolators on the short dimension
to support the riser from the room oor.
The greatest ex of the riser will be along its long
dimension, the riser’s short dimension will offer much
less low frequency exibility. Therefore, when possible,
avoid any support along the long dimension.
