DESCRIPTION
The MicroWedge MW12 is a collaboration between original
MicroWedge Series inventor Dave “Rat” Levine (owner of Rat Sound
Systems, Inc.) and the EAW Engineering Department, resulting
in dramatically upgraded performance and ergonomics. A 12-inch
woofer is paired with a 3-inch voice coil HF compression driver on a
horn that provides full yet controlled 90-degree horizontal dispersion.
All frequencies emanate from the exact same point, eliminating
crossover region problems and time/phase irregularities, as well as
optimizing coherency. The coaxial approach also contributes to a
very compact, low-profile footprint.
MicroWedge MW12 monitors are processor enhanced (rather
than processor dependant) for true “plug and play” operation. User
selectable single-amp and bi-amp modes are provided. The large
port on the front of the cabinet enhances LF response in coupling
with the floor, and this port houses both the carrying handle and
the passive/active mode switch. The port also contains dual input
connectors, keeping them concealed and protected, and allowing
wedges to be placed as close together as desired. Additional cable
can be stored in the port without impacting LF performance.
Rubber feet on the bottom of the enclosure reduce abrasion, and new
integral rigging hardware – also mounted on the enclosure bottom –
facilitates easy flying. The Baltic birch cabinets are protected with
EAW’s RoadCoat™ finish that’s extremely durable, and the rugged
steel grille keeps its distinctive shape even when stood upon. All
components are highly liquid tolerant – virtually impervious to spilled
drinks as well as natural elements like rain.
