CABLE AND CONNECTIONS

Each connector panel incorporates two Neutrik® Speakon® connectors. The second connector facilitates the ability to "loop through" to other SR-X speakers in the system. The diagrams below detail the cable-side connections.

Wire Gauges

Selection of the appropriate wire gauge is important to system operation. A cable that is too light will result in amplifier power being wasted due to the series resistance of the cable and in loss of low-frequency performance due to degraded damping factor.
