Hi, the minimum distance required is only 2" to allow the port to breathe. Your personal taste and room acoustics will be the factors to determine the right distance for you. It varies from one owner to the other and from one room to the other. Once the speaker is 2" away from the back wall it will interact with the room boundaries as a sealed speaker would.
