** 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” !

We recommend the use of this speaker in a bi-amplified system using

high-quality satellite speakers and amplifiers. We do not recommend the use
of this subwoofer with a passive crossover (coil), as this type of device will
adversely affect performance.
