PORTED ENCLOSURE:
Recommended Net Volume:
1.0 cu. ft. (28.3 ltrs.)
Recommended Port Tuning:
36.8 Hz
Port Type: “Slot” ports are recommended. See information above.

Net volumes given below do not include the air volume displaced by the speaker
(Driver Displacement). This value must be added to the net volume along with the
displacement of any braces and/or ports (if applicable) to arrive at a gross internal
volume. Air inside a port is not part of the effective net volume. Calculate ports as
solid, not hollow objects.
The dimensions given for the enclosure examples below take all applicable
displacements into consideration.

SAFETY NOTICE!
It is absolutely essential that the completed subwoofer enclosure
is mounted firmly to the vehicle with heavy steel bolts (1/2 inch
diameter) and large steel washers on both sides of the bolts. This
will reduce the likelihood of occupant injury in the event of a
collision or sudden deceleration.
