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
