From failing memory, there were two types. And the Beovision 11 used the second type. They can’t be swapped, just use stretch knit fabric to re-cover your original grille in the new color. P.S. Make sure the grille is firmly attached before letting go — I ripped one fabric corner open by having it fall off, onto the floor. [Edit: Maybe try to buy an old one? One such part # is 1605213, B&O calls that ‘BeoVision 10-46 Front Cover Silver'”]
