We are a dealer and use their products in our showrooms.
The wave wood provides both diffusion (with the cutout pattern) and absorption (with the foam behind). You can also get them with that front in a bass trap format. And they come in a variety of different colors / finishes and are very reasonably priced. The sound changes surprisingly depending on whether the pattern is horizontal or vertical, with vertical tending to widen the soundstage and provide better focus. You can see that they are using them to that purpose between the speakers and at the first reflection area. Sound and vision magazine in the U.S. had a write up about them not to long ago.
Bryson is to be commended for using acoustic treatment during a show. Most exhibitors don't bother.
