The AM404 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 40˚
x 40˚ coverage pattern. For full-range music reproduction, it
can also be used in conjunction with the AS118 low-frequency
loudspeaker.
