Up for sale is a used Yamaha DHR12M bi-amplified active stage monitor. Specifically engineered for dedicated floor monitoring applications, this model features a coaxial configuration that aligns the 12-inch woofer and the 1.75-inch compression driver on a single axis. This design guarantees precise phase alignment, critical directivity, and a minimal footprint on stage.

Featuring a premium plywood cabinet (unlike ABS plastic alternatives), it delivers outstanding acoustic clarity and excellent resonance control. It also includes a pole mount socket, allowing it to double as a compact front-of-house (FOH) or fill speaker.
