Wharfedale SW-12 Sub Black - 12" Home Theatre Subwoofer The Wharfedale SW-12 Subwoofer delivers powerful, controlled bass with audiophile-quality low frequencies, perfect for home theatre and music enthusiasts seeking immersive sound. Overview The SW series subwoofers combine innovative drive units, amplifier modules, and filter stages to balance power and sound quality. They provide remarkable sound pressure levels while maintaining precise control for an exceptional listening experience. Featuring non-pressed paper cones for increased self-damping, improved transient response, and enhanced structural rigidity, the SW-12 ensures superior bass impact. Copper-lined centre vents reduce magnetic distortion and improve heat dissipation for reliable performance. Optimised for high impact at low frequencies, the SW-12 is ideal for movies and music. Its cabinet finishes, including White Sandex and Blackwood Vinyl with a hi-gloss baffle, complement matching floorstanding speakers.
