Description
Sleek, slim, and modern subwoofer. Primarily designed for SFM modular towers as the foundation, however, these beautiful subs can be used as standalone pieces to compliment any room. Whether you take advantage of their slim profile to hide them behind a couch or stick them in the corners of your room as functional decorative pieces, the power is in your hands.
Compact Footprint. Formidable Punch. Seamless Integration.
Don’t let its conservative footprint fool you—the RBH 88-MS is engineered to deliver a surprising, physical punch that completely belies its size. Designed specifically as the high-performance foundation for RBH’s modular tower speaker systems (such as the 61-SF series), this dual 8-inch slot-ported subwoofer module injects your smaller home theater or dedicated 2-channel listening room with tight, impactful bass.
At the core of the 88-MS are dual proprietary 8-inch aluminum cone drivers mounted in a side-firing, vibration-canceling configuration. Hand-assembled with heavy-duty High-Density Fiberboard (HDF) to virtually eliminate cabinet resonance, it serves as the ultimate space-saving, audiophile-grade bass solution.
