The RM25ac is a bi-amplified, 3-way coaxial reference monitor that provides the accuracy, pristine imaging and precise transient response required of a studio monitor but with the directional control, power handling and output capability required in larger spaces. The coaxial and low frequency transducers are mounted in independent, asymmetrical chambers designed to minimize standing waves. In addition, the internal volume and porting are optimized for extended low frequency response. This combination results in a highly articulate low mid transient response and surprisingly visceral low frequency extension. Its shallow enclosure includes numerous M10 mounting points, while its rotatable 90° x 45° coaxial transducer supports either vertical or horizontal orientation.
