Ported Small speakers >10 feet away from wall


Got a pair of Dynaudio Evoke 10s that I am running out in the middle of an oblong room (roughly 12 x 30). Got a little micro V way back in the corner turned down low just to add some energy.   I think I like them with the rear ports plugged better.  Got a little tighter bass I think.  But I just set this up so will keep testing. 

What are others experience with rear ported book shelf that are far away from wall?
