Product Description
The ButtKicker
®
LFE is a patented 4 ohm low frequency audio
transducer that features a 3
1/4
lb. (1.48 kg) magnetically
suspended piston. The ButtKicker is musically accurate, has
powerful low frequency response, and is virtually indestructible
and maintenance free. With a natural working range of
approximately 5-200Hz, it is designed primarily to move
structure, not air, and to provide a much more direct method
of sound perception. Because it provides a more effective
sense of feeling than that produced by the speaker system,
the ButtKicker enables your subwoofer and speaker system to
function in their more natural, audible working ranges. Many
users wind up turning the sound system down when using the
ButtKicker, reducing the amount of sound that their signi Þ cant
others, family, friends and neighbors hear outside of the theater
area. For this reason, the ButtKicker is an ideal solution for
connected housing, such as apartments. We like to call it,
“spouse and neighbor friendly”.
For musician monitoring, stage and studio use, we recommend
using the ButtKicker
®
Concert which has more power in the 40
– 80 Hz range than the ButtKicker
®
LFE. Please refer to our

Product Description
How to Determine How Many Isolators You Will Need
Rubber isolators come in different weight capacities. Isolators
are designed to be partially compressed in application and
therefore are made with varying weight speci Þ cations. This
speci Þ cation (RDA-55, RDB-120, RDB-220, RDB-375) indicates
the amount of weight in lbs. that each isolator is designed to
support (per isolator) for greatest ef Þ ciency.
When used with furniture, a platform, or a riser, calculate the
total weight to be carried by the isolator, including the weight
of the platform, furniture and people. Divide this weight by the
total number of isolator feet to be used (i.e. a minimum of
3, a usual number of 4, more only when necessary). This will
give you the weight per isolator. Pick the isolator model closest
to your calculated weight.
Vertical vs. Horizontal Mounting
The ButtKicker was designed for optimal performance in the
vertical orientation, but will function at any angle. Movement
sensation is very different in the two axis, and only when speci Þ c
sensations are required should horizontal mounting be utilized.
Horizontal orientation will not damage the ButtKicker.
Please note that vertical installation is strongly recommended in
when mounting in chairs and other types of furniture.
