There is nothing "new" in there but now it is visible.
Each waveguide is covered by a cosmetic frame with stretched fabric over it.
The waveguides are "ugly" in how they have to be to do their job, that is why we cover them. The loose fluffy acoustic felt is important in how they work so if we made it look "tidy" they would be less effective. That is why we usually hide it all. In this case we had the opportunity to cover them in a way that they can be seen yet not look ugly.
