Mc, I'm gonna have 8 subs:)  


A man's got to know his limitations.
I agree with the two subs. Or even one good REL sub since you are using single ended. My speakers will play down to 25 hz and I still have two subs. I just bought a new car. One had a subwoofer option and the other did not. The sound is night and day. SVS will let you return your subs if you do not like it. 2- SB 2000 pros will probably blow your mind. If not they take them back. 
Have GE Triton One.R. Similar to your GE Reference. You don’t need a sub!
 However —- that Oppo ...
I upgraded to an Oppo 105D with full Modwright mod, including tube power supply and tube dac.  Wow!!!  Difference not subtle. Try it if you can.
Get back on that train.
