The Bose® RoomMatch® RMS218 VLF-Subwoofer Module Loudspeaker features dual Bose® LF18 18-inch high-excursion woofers, and a V-baffle design that reduces distortion while minimizing enclosure width.

Description

The Bose® RoomMatch® RMS218 VLF-subwoofer is designed primarily to extend the low-frequency response of Bose® RoomMatch® arrays down to 25 Hz. It features dual Bose® LF18 18-inch high-excursion woofers, and a V-baffle design that reduces distortion while minimizing enclosure width. The durable Baltic birch enclosure with 2-part polyurethane coating integrates with all RoomMatch® modules for reliable ground-stack applications. Use the RMS218 VLF-subwoofer with RMS215 subwoofer and full-range modules to create RoomMatch® 4-way systems.
