I am going to be installing some ceiling speakers in my house, which is undergoing a full renovation. However, I will wire all the rooms, and probably only buy speakers for the kitchen and living rooms.
What do these B&W boxes that go in the ceiling do? Can I make them myself, or put in cross pieces between the joists?
