A case for running speakers full range - Tekton Double Impact SE w/ SVS SB16 subs

I've finally had more time to experiment more and contrary to what I normally hear/read, I find running my speakers full range and adding the subs at 50hz sounds much better than relieving the speakers of <50hz activity. 

I see zero effects less dynamics, in fact i feel much more. I feel like the narrative of relieving the amp of the low freq creates more dynamics is probably just a theory created by people who have their speakers set up wrong or are using very small speakers.  

I definitely agree with rolling off bookshelf speakers because they don't play well low anyway, but I'm not sure I agree with cutting off big speakers that can dig low.. I say let them dig low, then let the subs barely augment.
