ENTED NCLOSURES
NOTE: Vb is the gross volume, which is the TOTAL internal volume, before any speaker and/or port displacement.
All external dimensions were based on the use of 3/4" (1.90cm) materials.
NOTE: When using enclosures other than recommended, call Technical Support for correct application.
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.
