I own the 1.8mkII also. I too have found that the bass can be a little heavy, but if you can pull them away from the walls(side and rear), this effect can be completely eliminated(at least in my room). I would try moving them around just to see the difference, they really rewarded me with very flat response top to bottom. The more I pulled them away from the walls the better they worked. I can give you measurements if you want, email me. Also, if they still don't sound the way you would like them to, I would play with some room dampening technics. If you have hardwood floors, try an area carpet. I use homemade bass tubes in the corners and on the sides as well as a few house plants and fake ficus trees behind each speaker. I have thought about replacing my Contours recently, but I am playing around with power,speaker,IC cables first. It will probably take me a good 6 months to settle on a set. I believe the 1.8's are the best value in the Dyn line. I found that they are more natural and less hifi sounding then either the 3.0 or 3.3. I have not heard the new contour line yet, they may be better, but I do not like the looks at all. To each his own.
