The AM12 is a 2-way passive enclosure that has been specifically designed for applications such as stadiums and arenas where high SPL and weather resistance are of prime importance. The AM12 has a 300 watt 12 inch (300mm) direct radiating reflex loaded low frequency transducer with a waterproof cone coupled with a 1 inch (25mm) exit HF compression driver mounted on a rotatable 80º horizontal x 50º vertical constant directivity horn. The enclosure is of a vertical trapezoid design and horizontally formatted to reduce sightline obstruction. The AM12 is finished, both internally and externally, in a textured, high-density polyurethane coating. It is supplied with a protective grille that is heavy galvanised and powder-coated and fitted with an integral water barrier to ensure product reliability over many years.
