VENTED ENCLOSURE APPLICATIONS
These boxes are the enclosure of choice for outrageous street bass and high performance SPL contests.
If space is not a problem and you want to get the most from your Solo-Baric L7, try one of these ported
designs. You will not be disappointed. Solo-Baric subwoofers will handle massive amounts of power in
any of the recommended enclosures, minimum or maximum. The smaller enclosures are best for use in
limited-space applications. The larger recommended enclosures will yield slightly more bass at the lowest
frequencies.
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 Solo-Baric 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 Solo-Baric 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 Maximum enclosure generates
a very fl at response curve and superbly extends
the sub-bass response.
Solo-Baric 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.
