A subwoofer adds weight and authority to any stereo system, so that the frequency response is expanded much further than with conventional bass drivers. With wharfedale subwoofers, the built-in amplifiers are designed to give a powerful response to these frequencies, while a continuous variable crossover provides seamless integration with the other speakers in the system. All models offer a phase adjustment for the additional alignment of the sound.
In a multi-channel system, a subwoofer is recommended to process the 'LFE' or low-frequency channel of Dolby Digital or DTS sound. The PowerCube offers the impact and dynamics to really bring the soundtrack to life without ever sounding woolly.
