AtlasIED model AH54-15-BSG "stadium horn" is ideal for directional sound distribution where full range reproduction, maximum intelligibility and high sound pressure levels are required. Applications include football stadiums, sports arenas, baseball fields, convention centers and auditoriums.

Weather resistant construction features of the AH54-15-BSG include a multiple screen configuration to prevent moisture from damaging internal components, a perforated aluminum screen covers the large horn mouth, a secondary screen is in place forward of the high frequency driver and a third tightly perforated screen protects the 15" cast frame woofer. A "weep" hole is also included on the back of the large horn "bell" to allow evaporation of any condensation that might build up internally.
