* 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" !
All specifications are subject to change without notice.
