X Series


Item number: 1614-XXXXX

The XM-4 is a powerful, passive stage monitor. It guarantees first-class transparency, assertiveness and feedback rejection. This makes it the first choice for monitoring speech and music on stage. The sturdy enclosure, made of multiplex birch plywood with durable PU coating is designed for tough days on the road. A particularly sturdy metal grid behind the acoustic foam protects the speakers.
