At what point in the chain are you sending the signal to the rig out?
Have you tried a FRFR type personal monitor, like something from EV, Mackie, JBL, ect....
There is some talk about FRFR speakers here:

For me I like using headphones, but if I want it loud I just use my studio monitors.
The problem maybe you are just not familiar enough with the 11R yet and have not learned how to tweak it for headphone, amp/cab, and speakers, each can be different.
The problem may also be you are sending the signal before the end of the chain to your speakers.
Open up the manual tonight and give it a read through. Open the pdf and do a search for Output to Amp, that will give you some insight on setting the out point in the chain.

I'm looking to see if Avid has any videos on this, if not, I may put one together in a few days.
Here we go, Avid has a video up that shows Output to Amp. Just know that the video is not quiet correct when they say the Mains ALWAYS send the full signal no matter what - if you bypass the cab/mic, its bypassed on ALL outputs.
