Rubicon R8a with Mono Sub 
Adding a subwoofer and extended low frequency response to your Rubicon R8a's system is easy using the 

Rubicon R8a’s LINE LEVEL inputs.  Below is a typical system set-up using the Samson Rubicon R10s 1 with a 

mixer and a pair of Rubicon R8a satellite speakers. The Rubicon R8a’s inputs utilize industry standard RCA and 

XLR connectors.  For a detailed wiring diagram, see the section “Rubicon R8a Connections” on page 12.  Follow 

the steps in the diagram below to set up your system.

• 

 Lower your mixer’s master outputs to all the way off. 

  

• 

 Connect the mixer’s left output to the Rubicon R10s' LEFT LINE INPUT and the mixer’s right output to 

the Rubicon R10s' RIGHT LINE INPUT.  Now connect the Rubicon R10s’ LEFT LINE OUTPUT to the input 

of the left Rubicon R8a , and the  Rubicon R10s' RIGHT LINE OUTPUT to the input of the right Rubicon 

R8a .

•  

 Run an audio signal (like some music from a CD) through your mixer and raise the level to a comfort-

able listening level.

• 

 Now adjust the FREQUENCY control to the desired frequency.   You can also use your ears by adjusting 

the FREQUENCY control to the frequency that sounds good to you.  A good place to start is about 70 

Hz.
