A subwoofer provides a majority of the ultra-low frequencies within a Hi-Fi or Home Cinema system. A standard woofer in a speaker would not be able to produce the low frequencies of that of a subwoofer. Although a powerful subwoofer promises to deliver ‘booming’ and ‘thudding’ bass, it can often be an understatement for sound that can be dull, powdery or just numb. It is surprising to learn that bass also requires detail, just like treble does. However, with bass, you need a fast response in order to reproduce sounds accurately without being exaggerated or ‘fluffy’. A good quality cable is an ideal investment to get the best out of your subwoofer. Thankfully, Audioquest has recognised this by developing a range of various subwoofer interconnects. One of these is the Audioquest Sub-3. Silver-Plated Copper (SPC) always provides superior performance for video and digital audio. Unfortunately,when used for full range analoge audio, the discontinuity of plating silver over copper causes high frequencies to sound edgy and harsh. However, when used only for subwoofer frequencies, SPC's "artificial edge" actually enhances the articulation and intelligibility of low frequency information. AudioQuest instructs that you do not use Sub-3 as a full range audio cable. All insulation slows down the signal on the conductor inside. When insulation is un-biased, it slows down parts of the signal differently, a big problem for very time sensitive multi-octave audio. AudioQuest’s DBS creates a strong stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS pack’s batteries will last for years. A test button and LED allow for the occasional battery check. A novel plug design enables a perfect heat-free connection between cable and plug XLR plugs are also available.
