PFW ENCLOSURE DESIGN NOTE:
When constructing an enclosure for the PFW1 051, please ensure the subwoofer
is
mounted
in
so the cone does not come into contact with any object (back of seat)
when
in
use. This may require the installation of a grill or recessing the subwoofer
into the enclosure. The subwoofer may be damaged if it comes into contact with any
surface while
in
operation.
ENCLOSURE DESIGN NOTES:
• All enclosures should be constructed of 3/4"
MDF.
Particle board
is
not suitable for
an enclosure and may result
in
the subwoofer system offering poor performance or
the driver may be damaged.
• All panel joints should be sealed with appropriate caulking (latex or rope caulk).
Do not use Silicone.
• All joints must be secured with screws or nails.
• Any panel exceeding 4 square feet
in
area (2'x2' or 1'x4' for example) should be
braced internally for resistance to flexing
• All enclosure volumes are net and do not include the displacement of the sub-
woofer, ports or bracing. Please include these items
in
your enclosure calculations
• Clarion does not recommend the use of passive crossover networks with our
subwoofers (inductors, chokes). Use an amp with an electronic crossover for the
subwoofer to achieve optimum performance.
• Where noted, please use a subsonic filter to protect your Clarion subwoofer from
over-excursion situations that may cause damage.
• All specifications are subject to change without prior notice.
