Input Connections
The RSX has a pair ¼" (TS) phone and Speakon® connectors wired in parallel. This enables you 
to directly connect an extension cabinet to an RSX speaker. 
Only use one ¼" or Speakon® connector as an input connector from an amplifier. Typically, you 
will only connect a single extension cabinet to an RSX cabinet, but it is possible to daisy-chain 
multiple cabinets. When wiring multiple cabinets in parallel, attention must be paid to the over-
all impedance of the loudspeaker system, and the minimum load impedance of the amplifier. 
Please see the chart below for typical impedance calculation for multiple speaker arrangements. 
Typical Impedance Calculations 
16Ω + 16Ω = 8Ω
8Ω + 16Ω = 5.3Ω
8Ω + 8Ω = 4Ω
8Ω + 16Ω + 16Ω = 4Ω
16Ω + 16Ω + 16Ω + 16Ω = 4Ω
4Ω + 8Ω = 2.7Ω
4Ω + 4Ω = 2Ω
It is recommended, especially for installation applications, to use Speakon® style connectors 
because they lock into jacks providing a secure connection, are able to handle high current, and 
the contacts do not cause a momentary short when connecting to an amplifier or speaker cabi-
net.
