The SW series subwoofers offer an unprecedented performance in its class. The revolutionary drive units, amplifier modules and filter stages are present in all models. They achieve the perfect balance between power and sound quality, provide remarkable sound pressure levels, but retain sufficient control to be considered quality as audiophiles.

The new series SW subwoofer comes with many new features. They now come with non-pressed paper cones to improve the automatic damping to increase the transient impact and increase the structural rigidity of the cone itself. The central ventilation holes are lined with copper in order to reduce magnetic distortion, and to improve the heat dissipation.



Using solid and well-designed power amplifiers SW subwoofers are optimized for high impact at low frequencies, ideal for movies or music. The different finishes available, these subwoofers add aesthetics to with matching floor speakers.

Adding a subwoofer adds weight and authority to any stereo system, whereby the frequency response is much more extensive than with conventional bass drivers. With Wharfedale subwoofers are built amplifiers designed to deliver a powerful response to these frequencies, while a continuously variable crossover provides seamless integration with the other speakers in the system. All models provide a phase adjustment for additional sound adjustment.


In a multichannel system, a subwoofer recommended for handling the 'LFE'- or low frequency effects channel Dolby Digital or DTS sound. PowerCube offers impact and dynamics to make the soundtrack to life without ever sounding tree or blurry.
