Looks like that box is opaque.

If you start by applying the media THEN cut away, you need to make sure 
that the other object also have rgbt 1 as it's pigment.

The best approach here is to do all of your CSG before adding your 
media, add the transparent pigment at once to the totality of the 
composite object, then add the media.

DO NOT use union. You can use merge, intersection and difference. As 
union don't remove any internal surface, it'll wreak havoc with your media.
