Like any other cables, the subwoofer cable can make a difference when used with a subwoofer over a regular RCA cable. Most people tend to “skip” on getting a quality subwoofer cable but the guys at Verastarr is showing that can be a mistake. The Silver Signature Subwoofer cable not only increases the depth of the bottom end but also gave it a bit more tightness (slightly tighter bottom end than the Silver Reference). We tried this a B&W ASW825 and found the bass was a bit tighter and slightly more forceful in its punch.
This cable was a former demo unit. Very minor signs of use.
