The Episode Terrain Landscape Speaker System is a low-cost landscape system, designed to bring stunning sound to the outdoors. This kit includes four 4" satellite speakers, stakes, and an 8" burial subwoofer -- perfect for use with a standard multi-channel or 2-channel amplifier. A two-way speaker design and DVC subwoofer allows this system to play lower and louder, while a simplistic wire management system makes installation easy. Plus, Terrain can be expanded up to an 8.2 system.
