* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1 W / 1 m) 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 Notes
Net volumes given above 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 W7’s employ a pole vent to remove heat and pressure from the inside of the speaker.This vent is located at the rear of the speaker. A minimum distance of 0.75 in (19 mm) is required between the back of the speaker and any wall of the enclosure to allow proper operation of the pole vent.

The dimensions given for the enclosure examples above take all applicable displacements into consideration
