3.2 ArcM 12 overview

The ArcM 12 has multiple working angles, allowing it to be used as a near field booth 
monitor or conventional stage wedge, as well as having the ability to be pole mounted or 
wall mounted for front-of-house purposes. In terms of mobility, measures have been taken 
to reduce weight, while maintaining an ergonomic design to appease manual handling 
requirements. Acoustically, FEA analysis has significantly reduced port noise and air distortion. 
The 12” ArcM 12 is unpowered, allowing it to integrate with touring operators’ existing 
infrastructure.
