Key Features
Easy To Install: The ultra-flat design allows for installation over flat surfaces, across rooms, under floors, around corners, and in vehicles. Use it with our Super Slim Speaker Wire Connectors to easily connect your speakers.
Adhesive Backing: The adhesive backing allows you to run the wire on a wall, ceiling, baseboard, or any other flat surface, without the need for a cable raceway or cable retaining clips.
Paintable: The textured surface is similar to that of white masking tape, which allows it to be painted or spackled to hide the wire from casual view.
Super Slim and Flat: Measuring less than 0.02" (0.4mm) thick, this speaker wire lays flat against the surface it is attached to. This allows it to be easily routed around corners, while remaining flat and easy to hide from view.
Four 18 AWG Pure Copper Conductors: Although the conductors are flat, they have the same surface area as traditional round 18 AWG conductors, ensuring that your speakers get the same voltage levels and frequencies, without any signal loss.
