the compvx generates more sound pressure than competing subwoofers on the market & excels
when used in the recommended sealed boxes. These sealed enclosure designs give the smoothest
response w/increased energy at the lowest frequencies, 20 to 30hz. These designs deliver massive
amounts of highly-accurate bass & can be driven w/punishing levels of amplifier power.
the compvx 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 flat response curve & superbly extends the subbass response.
compvx woofers perform well in any size sealed enclosure between the compact & sq volume
recommendations. These systems will exhibit benefits of both designs: compact produces high-impact
bass, & 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 w/the airspace inside the enclosure & include the displacement of the woofer.
all sealed-enclosure airspace should be filled to 50% loose poly-fil (polyester fiberfill) stuffing. Do not
make the airspace greater than the sq, maximum enclosure volume, recommendation.
