* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1W/1m) is not an accurate indicator of a subwoofer's
output capability and should not be used as a comparison to other
subwoofers to determine which one is "louder".

ENCLOSURE SPECIFICATIONS |
| 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. | |
