The Horizon Series HS-1 two-way, indoor/outdoor loudspeaker has staying power. It's been reliably adding atmosphere to backyard barbecues for years. The HS-1's UV-resistant, paintable enclosure, durable aluminum grille and stainless steel hardware keep it from rusting or corroding. And the Tractrix® Horn and lower frequency woofer keep you grooving at the grill with powerful detailed performance.
