The Episode Terrain Landscape Speaker System is a low-cost immersive audio system designed to bring stunning sound to the outdoors. This kit includes four 4" satellite speakers, stakes, and a booming 8" Episode Terrain Hardscape subwoofer -- perfect for use with a standard multi-channel or 2-channel amplifier. A two-way speaker design and subwoofer with an oversized 1.5" DVC design allows this system to play lower and louder, while a simplistic wire management system makes installation easy. Plus, this terrain system can be expanded up to an 8.2 system.
