I agree with Brian. When I first got my Room Lenses, I put them into a living room system that was both lower res and had real room problems. They worked like a charm. Now, in a good dedicated, well treated room with a much higher res system, they hurt the imaging if I put them in front of the speakers. Specifically they diffuse the image by pulling it out from the center toward the sides. I still use them as diffusors, but I keep them out of the image-forming area in front of the speakers.
