Product Description
The MJF-210 low-profile high-power stage monitor reproduces audio faithfully with high intelligibility at high outputs levels with ample low-frequency headroom. The self-powered MJF-210 exceeds the stringent requirements of today’s touring applications, withstanding the rigors of road and stage while occupying a small, lightweight footprint and a fraction of the truck space of similar monitors requiring external amplification.
