The addition of a sub-woofer will add weight and authority to any stereo system, extending the frequency response much further than conventional bass drivers. With the Wharfedale subwoofers, the built-in amplifiers are engineered to provide a powerful response at these frequencies, while a continuously variable crossover provides seamless integration with the other speakers in the system. All models offer a phase adjustment for the additional matching of the sound. In a multi-channel system, a sub is recommended to handle the ?LFE? or Low Frequency Effects channel of Dolby Digital or DTS sound. The PowerCube provides the impact and dynamics to really bring the soundtrack to life without ever sounding boomy or woolly. Wharfedale SW Subwoofers The SW-150, SW-250, SW-300 and SW-380 represent the state-of-the-art in home cinema subwoofers. With large format drivers and very powerful amplifiers, they are able to reproduce the true dynamics and scale of the original recording without compromise. A unique curved cabinet (on the larger models) not only improves aesthetics, also significantly increases the overall rigidity of the cabinet, reducing resonance and overhang to almost negligible levels. An advanced microprocessor controlled filter section preserves optimum signal purity, whilst offering the consumer the best possible user interface. Fully remote controlled (not SW-150) with four programmable memory settings, allow customization of crossover, phase and volume, all form the users listening position. Advanced cone diaphram The new KEVLAR cones introduced on all the SW-models are marvels of materials technology and application. Although huge, they remain completely controlled at all times. A band new Class AB amplifier has been specifically designed for the models. Very low distortion, exceptional headroom, and a high internal electrical damping factor provide accurate control of the speaker, for performance well above the specification.
