Coax defines a type of cable with one central conductor surrounded by an insulator and then surrounded by another conductive "shield". This "shielding", generally being grounded, serves to minimize electrical interference from getting into the signal.

This type of cable can be used for various tyoef of signals that benefit from shielding. This includes (but is not limited to) the RF type signals from cable companies, FM and TV signals from an antenna, Video signals, both of the composite and comopnent nature and aline level audio signals.

Some people choose to use the TV style coax cable for video signals and some line level signals like subwoofers with fairly successful results. That's why those adapters are so popular. a 25' roll of RG6/U with "F" connectors is a lot cheaper as an expensive subwoofer cable and just as effective.
