You could attach these drivers to anything -- the inside or outside of walls, large sheets of glass, etc.

NXT had a flat speaker technology being used by a variety of manufacturers (Pioneer, Sony, NEC) to make flat speakers. It is also possible to turn a laptop screen into a speaker with this technology.
