Although we recommend that you avoid running line-level audio in your walls, sometimes it is necessary. When it is...this is the best cable we've found for the task! Just be sure to keep it well away from all AC wiring.
Line level audio cable carries less power than standard speaker cable. As a result, it is very susceptible to noise interference from power cables and the like. Monster provide a heavy, thick plastic shielding to prevent interference and signal loss. Monster is the best choice for quality sound.
