The ceilings are going to be 12-14' high so I did not want to do ceiling speakers. I don't love the look of speaker grills in walls and we will not have cabinets to hide in the way the room lays out. Can I mount speakers in the walls and just have some type of deal that looks like artwork or picture but actually allows the sound to come through? Was wanting to do pics of the family and have the front speakers at least hidding from view. Any suggestions where to get this done at? Best quality.
