SpeakerCraft Terrazza is a value-priced outdoor speaker system that over-delivers on performance. Unlike high-performance landscape systems that require expensive high-power amplifiers, the Terrazza Landscape Series is designed to be used with lower-powered distributed audio amplifiers or extended audio zones (like Zone 2) from conventional AVRs. Each Terrazza outdoor speaker system comes with a subwoofer and matched four 4-in. Terrazza satellite speakers for an exceptional sound experience. This item, the SC-TERR-2.0, is a Terrazza speaker expansion kit that features 2 add-on, matching 4-in. landscape speakers. It is compatible with SC-TERR-4.1-HS or SC-TERR-4.1-BU outdoor speaker systems.
