Kicker L7R Série Manuel D'utilisation page 5

The ported Minimum design increases bass effi ciency and fi ts in many space-limited applications.
Although it is the smallest recommended ported enclosure, the output from 30 to 80 Hz will be
considerably higher than that of any sealed box. The Maximum ported design has even more output in
this crucial frequency band. The Maximum is the largest and most effi cient enclosure design.

The L7R generates more sound pressure
than an equivalently-sized round speaker 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
amplifi er power.
The L7R high performance suspension system
can operate in a larger sealed enclosure. This
maximum enclosure volume application is ideal
for SQ (ultra sound quality) installations and
generates a very fl at response curve, extending
the sub-bass response.
L7R woofers perform well in any size sealed enclosure between the Minimum and Maximum volume
recommendations. These systems will exhibit benefi ts of both designs: Minimum produces high-
impact bass, and Maximum 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 fi lled to 50% loose poly-fi l
(polyester fi berfi ll) stuffi ng. Do not make the airspace greater than the SQ, maximum enclosure volume,
recommendation.
