A quick look at the "Argent Room Lens" indicates they are no more than a method of diffuser panel. Would need more detail on the dimension to know what the effective frequency range would be. I am not saying that is a bad thing, just pointing out what the effectively are.
I don't see them "reshaping" the sound waves to your listening chair per se, so much as diffusing the side emissions from your speakers in what appears to be a recommended placement, which again, is not bad thing, or providing diffusion wherever they happen to be.
