The RMS22ac is a dual 12inch, direct radiating reference subwoofer that is designed to provide the precise transient response and extended low frequency response required of a studio subwoofer but with the power handling and output capability required in larger spaces. Its 4inch voice coils, strong neodymium magnets, and innovative laminar flow ports permit low frequency extension to 22Hz in an enclosure of the same size as the RM22ac Dual 12inch Coaxial Reference Monitor. 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 eye bolt points and two M10 yoke points.
