Speaker Placement

I would set them up in the room. Preferably equidistant from where you will be sitting.

Naturally, YMMV. Works in my room, along with some room enhancement-ceiling/first reflection damping. Multi sub setup as well.

I’ve heard the GE Tritons sound pretty convincing.

Thanks!  Appreciate the help will check them out. 

My sense is that your Triton Reference speakers with multiple sub bass speakers, passive radiators and a 12 hz bass response will overdrive your modestly sized room.  Placement options will be limited in this space and your listening position is likely to be next to a wall, which amplifies the bass issues.   A better solution would be to buy new speakers that work well in a smaller space, like Harbeth, Spendor etc.  

I see some room treatments in your future.
