Did you tell the dealer what size room you had before you purchased the speakers? I ask this question because while I haven't found the specs to this speaker I think your room is too small for them. Are you sitting on a concrete slab or what type of floor? It looks like these are acoustic suspension which would reduce some bass bloat. Have you given them enough time to break in? If not put on a cd and let them cook for a couple days. These speakers need space to breath. A room that size should not have a speaker that goes below 40Hz. The bass could be overwhelming. Acoustic dampening could help. I have heard systems setup like yours with smaller speakers and a small sub and it integrated much better than a floorstander. I have had the same problem in my 13x14 foot room. But I have two 12" Dali subs (acoustic suspension)that integrates well.
Try placing the speakers at the long square end of the room. I would start with them about 6 feet apart and sit about 6 feet away and make sure your tweeter is at ear level or close. See if it helps. The position of the amps may not change much. Placing them on an amp stand may have some positive effect.
I still suspect the speakers are not broken in or room is too small. Wires (interconects or speaker wires) could be a factor too.
