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" (300mm) direct
radiating reflex loaded low frequency transducer with a
waterproof cone coupled with a 1" (25mm) exit HF
compression driver mounted on a rotatable 80˚ horizontal x
50˚ 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.
