Notes: All specifications are subject to change without notice.
1) All enclosure information assumes no leaks with normal fill (interior walls covered with acoustic damping material).
2) External dimensions, driver and port displacement for net volume are based upon all 3/4" thick enclosure construction.
3) A -24dB/oct. subsonic filter set at or below the tuning frequency (Fb) is recommended to prevent over-excursion.
4) Minimum recommended port area is 15.9in (103cm), or round equivalent port diameter of 4.5” (11.4cm). More port
area and/or flaring is preferred when feasible, particularly for a larger enclosure with lower tuning frequency (Fb).
5) Small or irregular shape enclosures may require at least one internal bend or an external port to fit required length.
