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.
