The RoomMatch RMS218 subwoofer integrates with Bose RoomMatch Progressive Directivity Array systems for program material that extends down to 25 Hz, allowing use in the most demanding venues.

The RMS218 subwoofer features dual Bose LF18 18-inch high-excursion, 4.5-inch voice coil, neodymium-magnet transducers that increase power handling and reduce power compression. The V-baffle design features a large center port to reduce airflow turbulence and distortion, while minimizing enclosure width to allow integration with all RoomMatch modules. The RMS218 enclosure is constructed of rugged, Baltic-birch plywood finished in a 2-part polyurethane coating that is highly resistant to scratches and scuff marks. An optional RMSFLY218 kit allows suspended array applications.

The RMS218 VLF-subwoofer module can be used with RoomMatch full-range array modules to form high-impact, 3-way systems. For the ultimate performance RoomMatch system, the RMS218 VLF-subwoofer can be used with RoomMatch RMS215 and full-range modules, to form 4-way systems. The RMS218 subwoofer has a rated frequency response of 30-200 Hz (+/- 3 dB) and usable frequency range (-10 dB) that extends to 25 Hz. Long-term continuous power handling is rated at 2500 watts (2-hour test) which provides peak sound pressure level capabilities of 141 dB.

The new RMS218 subwoofer module will be available through authorized Bose dealers and integrators beginning October 2013.
