KM subwoofers perform well in any size sealed enclosure between the Compact and SQ volume
recommendations. These systems will exhibit benefi ts of both designs: Compact produces high-
impact bass, and SQ generates low bass frequency protraction. Overall, the system will sound
more like the recommended enclosure design it is closest to in enclosure volume. These enclosure
recommendations have been calculated with the airspace inside the enclosure and include the
displacement of the woofer.

Vented Enclosures: These boxes are the enclosure of choice for outrageous street bass and high
performance SPL. If space is not a problem and you want to get the most from your KM subwoofer,
try one of these ported designs.

The displacement of the port must be calculated and added to the internal volume of the fi nal design.
The dimensions for X, Y, and Z may vary based on the thickness of the material used to make the port.

Sealed Enclosures: The KM subwoofer
generates more sound pressure than competing
marine subwoofers on the market and excels when
used in the recommended sealed boxes. These
sealed enclosure designs give the smoothest
response with increased energy at the lowest
frequencies, 20 to 40Hz. These designs deliver
massive amounts of highly-accurate bass and can
be driven with punishing levels of amplifi er power.

The KM subwoofer high performance suspension
system can operate in a larger sealed enclosure.
This maximum enclosure volume application is
ideal for SQ (ultra sound quality) installations. The
SQ enclosure generates a very fl at response curve
and superbly extends the subbass response.
