SEALED ENCLOSURE APPLICATIONS
The Comp generates more sound pressure than competing 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 30Hz. These designs deliver massive amounts of
highly-accurate bass and can be driven with punishing levels of amplifier power.
The Comp high performance suspension system can operate
in a larger sealed enclosure. This maximum
enclosure volume application
is ideal for SO (ultra sound quality) installations. The SO enclosure generates
a very flat response curve and superbly extends the subbass response.

Comp woofers perform well in any size sealed enclosure between the Compact and SO volume
recommendations. These systems
will exhibit benefits of both designs: Compact produces high-impact
bass, and SO 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.
All sealed-enclosure airspace should be filled to 50% loose poly-fil (polyester fiberfill) stuffing.
