The AM3 is a high performance three-way, fully horn loaded horizontal format enclosure designed for outdoor applications such as sports stadia and arenas. It features a Hybrid™ low frequency section comprising a 15" (380mm) driver that is reflex loaded to extend the LF output to below the natural horn cutoff point. The 10" (250mm) mid-horn features a unique "phase-ball" loading device and is teamed with a 70º x 40º horn- loaded 1" (25mm) exit compression driver for efficient mid-HF performance. The enclosure has a textured, high-density polyurethane coating applied both internally and externally, plus a galvanised steel grille with a water barrier to ensure product reliability over many years.
