I have owned Grand Veenas twice and they are indeed very good speakers. But your room does seem on the small side of ideal. I would be more concerned about the distance of the listening position from the speakers than having too much bass. They don't seem to work nearly as well in the near field. The de capos might be a better choice in your space. I have heard them a few times in a small room and they were quite special.
But if you insist on the grand veenas , use the rear spikes to tilt the speakers forward slightly.
