amplified output 

to your IW-SUB10 

or your tactile

If  you  are  using  the  XJ-300R  to  drive  a 
subwoofer  (including  Earthquake’s  THOR 
In-Wall SUB10), then you will need to set the 
crossover below 100Hz.  
If you have a large subwoofer such as a 12”, 
15”, or even 18”, then you will have a great 
response  with  the  crossover  set  to  the  12 
o’clock setting or minimum setting.
For use with a 8” or 10” subwoofer, you will 
find the 12 o’clock and 2 o’clock setting to be 
the best range.

Note that the high level input 

stage on the XJ300R has a 

common mode ground. 

Therefore, you cannot use a 

bridge mode amplifier as a 

high level input.
