Jason, that's correct. The W series all have their own enclosures that inside the wall are sealed so as to prevent any acoustical energy from venting into the wall cavity. The actual ports (for the ported models) are on the bottom of the exterior "on-wall" frame. It's one of the advantages we cite over other manufacturers whose speakers are loaded into the wall cavity, which produce a surprising amount of output into the neighboring room.
