The AM604 is an extended range mid/high system which has been developed specifically for large scale install applications such as arenas and stadia. It can be used in either a bi-amplified or optional 2-way passive configuration. As a stand-alone system it provides exceptional intelligibility over its uniform 60º x 40º coverage pattern. For full-range music reproduction, it can also be used in conjunction with the AS118 low-frequency loudspeaker.
