Many so-called ‘full-range’ loudspeakers cannot reproduce the low bass frequencies found on most music and movie discs, which are necessary for the accurate reproduction of the original recording and help to impart a natural ambience that is immediately recognisable by listeners as being closer to ‘the real thing’. Of course, movie DVDs incorporate a dedicated bass channel for the deeper bass special effects, but a properly designed sub-bass system will not only reproduce these with accuracy, it will also augment the output of conventional stereo and surround loudspeakers with very low frequency bass that is felt rather than heard. The result is greater fidelity. The system with a wider bandwidth will always sound more realistic and ultimately more entertaining and stimulating. In many cases, the best way, the only way, to add these critical bass frequencies is to introduce a correctly designed sub-bass system, one which not only has the technical ability to reveal the deepest sounds, but will also integrate seamlessly with the loudspeakers so that your system speaks with one deeper, more natural voice.
