SW subwoofers come with a host of features, such as non-pressed paper cones to increase the structural rigidity, as well as increased self-damping, and improved transient impact. The centre voice coil vents are copper lined to reduce magnetic distortion and improve heat dissipation.

A continuously variable crossover control (30Hz C 150Hz), Phase switch, and Volume control make it easy to contour the subwoofer to blend seamlessly with Wharfedale's main speakers. The Auto Sense feature allows the sub power to automatically enter and exit standby to save power during idle periods.

The SW subwoofers use reliable, well-engineered power amplifiers and are optimised for high impact at low frequencies, and are ideal for home cinema and music.
