Some subwoofers have the option of RCA (unbalanced) and XLR (balanced) for a connection method. Generally, RCA is fine for the typical 3 to 6-foot connection. For longer connections, or for those in interference-prone environments, XLR is the better choice. (Note that running a low-voltage connection alongside an AC power line is not a good idea to begin with.)
