Surround channels within the wall
IW-155SR places the surround channels inside the wall instead of in cabinets beside the seating. A switch selects dipole or bipole operation to suit the intended surround arrangement.
The in-wall format is useful when visible speaker cabinets would interrupt a walkway or the room layout. Confirm the wall opening, mounting depth, and wiring route before installation.
