NOTE:
The port shown can be placed on any face of the enclosure as long as the port ends are not obstructed.
NOTE:
When using vented enclosures, for maximum reliability and power handling ensure that a subsonic or "infrasonic" filter is used so that
only usable low frequency signal is sent to the subwoofer.
