Fulcrum Acoustic RM22ac Self-Powered Dual 12″ Coaxial Reference Monitor

RM Series loudspeakers are 3-way coaxial reference monitors that provide 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 RM22ac 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 an extended low-frequency response. This combination results in a highly articulate low mid transient response and surprisingly visceral low-frequency extension. The RMS22ac is available both in the standard studio version, which includes four M6 mounting points for use with third-party isolation feet and in an installation version which includes twelve M10 eyebolt points and two M10 yoke points. It’s rotatable 90° x 45° coaxial transducer supports either vertical or horizontal orientation.

Sound, innovative acoustical design combined with onboard TQ™, Level 1 processing provides exceptional clarity and stability, and precise transient response even at very high sound pressure levels. Four back panel selectable presets to optimize the response for either vertical or horizontal orientations, whole or half-space. A full complement of input filters and delay, as well as signal levels and amplifier status, may be accessed via Ethernet, using Armonía Pro Audio Suite™ control software. In addition, a pre-output EQ stage is available for programming custom presets. These presets may be saved and later recalled using the back panel Preset Select button or software.

The RM22ac’s robust transducers are powered by two 1050 watt amplifier channels, designed and manufactured in Italy by Powersoft. Powersoft amplifiers incorporate state-of-the-art Class-D technology to produce extremely high efficiency, low noise, and low intermodulation distortion in compact and lightweight packages.

The RM22ac is primarily intended for use as a mid- to far-field monitor in recording studios and A/V production suites; but it is also an ideal choice for cinemas, museum exhibit spaces, multimedia presentation facilities, boardrooms, and high-end home theaters: any environment in which pristine audio quality is desired and a protective grille is not necessary.
