The incredibly lightweight Adamson M12 monitor delivers everything you need in a low profile stage monitor: fantastic gain before feedback, precise pattern control and high output with extremely low distortion. Together, the symmetrical trapezoid design and the 65° x 65° waveguide, allow any two M12s to operate as a mirrored pair. The M12 exhibits remarkably low distortion thanks to the qualities of its advanced multi-layer Kevlar cone driver.
The M12 is available in Active (Bi-amped), or Active / Passive switchable configurations.
