The RM25 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 RM25 is typically installed behind perforated cinema screens or acoustically transparent cloth, flush-mounted in walls, or mounted in free space in A/V studio control rooms. This makes it an ideal choice for cinemas, planetariums, museum exhibit spaces, A/V production suites, multimedia presentation facilities, and high end home theatres: any environment in which pristine audio quality is desired and a protective grille is not necessary.

Fulcrum Acoustic’s TQ™ processing is an integral part of the RM25 design. Sound, innovative acoustical design combined with state of the art digital processing leads to exceptional clarity and precise transient response, even at very high sound pressure levels. The required digital signal processing can be provided by one of many supported platforms.

The coaxial and low frequency transducers are mounted in independent, asymmetrical chambers designed to minimise standing waves. In addition, the internal volume and porting are optimised for extended low frequency response. This combination results in a highly articulate low mid transient response and surprisingly visceral low frequency extension. The absence of a grille and its supporting structures reduces reflections and diffraction, which contributes to the RM25’s spacious, well-defined image and open sound stage. Its shallow enclosure includes numerous M10 mounting points, while its rotatable 90° x 45° coaxial transducer supports either vertical or horizontal orientation.
