The Totems are really warm and have surprising bass depth, but when watching movies, dialogue never sounds as sharp as it should.You’ve just got fat lower mids, which takes away from the diction of the speech.
Use the audio or bass/treble adjustment on the Onkyo and take the audio off movie and onto music/speech if it has it, or drop the bass a little with the EQ and this will bring up the "sharpness" of the speech.
Or bring the speakers well out from any walls, this also will fatten up the lower mids with excess bass
