ENCLOSURE DESIGN NOTES:
• All enclosures should be constructed of at least 3/4” MDF. Particle board is not
suitable for any 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.

SFW ENCLOSURE DESIGN NOTE:
When constructing an enclosure for the SFW1051, 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.
