Was wondering if someone on here has in wall speakers and could tell me about their experience installing them and living with them. I live in a condo on the bottom floor and my fireplace column is shared with my neighbor above. My concern obviously is with sound transfer and the vibrations. I was looking at getting in wall speakers with an enclosed back to minimize the sound transfer, but now am leaning towards a wall mountable satellite speaker specifically the Definitive Technology ProMonitor 800. Any help is greatly appreciated.
