NOTES:
• This is the exact outside diameter of the subwoofer including the rubber mounting

dimension to facilitate access to the mounting screws beneath the gasket.
• • This is the exact mounting depth of the driver, and does not include provisions
for air flow from the vented pole piece. Clarion recommends at least 1" of clearance
behind the driver to facilitate air flow and proper cooling.

PFW ENCLOSURE DESIGN NOTE:
When constructing an enclosure for the PFW1 051, please ensure the subwoofer
mountedinso the cone does not come into contact with any object (back of seat)
wheninuse. 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 whileinoperation.
ENCLOSURE DESIGN NOTES:
is
• All enclosures should be constructed of 3/4"
an enclosure and may resultinthe 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 feetinarea (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 subwoofer, ports or bracing. Please include these itemsinyour 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.

To
calculate the volume of an enclosure, measure the outside dimensions (Length,
Wight and Height), subtract the thickness of the material then multiply the three
numbers together to get the volumeincubic inches.Toconvert to cube feet, divide this
number by 1728.
We will use the 1.7 Cubic foot vented enclosure for the PXW1251/PXW1252 as an
example.
Net Internal Air Volume: 1.7
Vent Dimension: 3" 10 x 6-1/2" Long
Driver Volume (Vd) = 0.15fP
Eg: Material Thickness: 0.75"
External Length: 11.75" Internal Length: 11.75 External Width: 25" Internal Length: 25 External Height: 15" Internal Height: 15 -
Equation: (10.25" x 23.5" x 13.5") + 1728 = 1.882
To
calculate the area of a cylinder (for a vent), the equation is:
Radius x Radius x 3.1416 x length
Eg:
Vent Diameter: 3.5"
Equation: ((1.75" x 1.75" x 3.1416) x 5.75) + 1728 = 0.032
Total Enclosure Calculations
To
perform a complete enclosure calculation:
consume air volume from the enclosure.

For wedge style enclosures, you need to find the average depth of the angled panel.
In
the case of the example below, add 9.75" to 13.75" and divide by 2 to get 11.75".
The calculations then become the same as for a rectangular enclosure.
Average External Depth Equation: (9.75" + 13.75") 7 2 = 11.75"
Internal Depth Equation: 11.75" -
