The placement of my subs follows the guidelines recommended by REL. There is no room to place the subs inside of the speakers, with others subs I have tried front firing placement and placing the subs opposite to one another..... I think they sound best, in my room, as shown. I did snap some pictures and asked REL if they thought anything needed to be adjusted and they said the subs are well placed.
One big difference is adding proper room treatments, I am still working on this, but have notice smoother bass.
I hope you enjoy your RELs, and wish you happy listening.
