The sweet spot with my Zerius speakers got wider and wider as they broke in.
Also, my experiments with toe-in surprised me: the image snapped into better focus and the sweet spot got wider when I toed them in way more than seemed logical. Right now, they aim at a point that's about 2 meters in front of the listening spot. It works great.
Who knows, this might be specific to my room, but the lesson is don't be afraid to experiment with placements simply because they don't make sense to you.
