Connecting Cables
Heavy duty loudspeaker cable should always be used, with a minimum wire size of 12
gauge (1.5mm
2
), and preferably 10 gauge (2.5mm
2
) for longer runs, keeping the run as
short as possible. This helps to avoid wasting amplifier power in the resistance of the
cable. High cable resistance also lowers the
damping factor
of the amplifier that affects its
ability to control loudspeaker cone movement. Losses due to undersized cable and long
runs are clearly illustrated in the table below. Please use this table to determine the most
suitable cable size and maximum run for your particular application.
