*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”. ***Re (DC resistance) is measured with
the voice coils in series, for parallel-wired specification divide Re by 4. All other specifications remain the same.
