    Precision Audio That Hits Every Note
    The RBH Sound 661-SFM is a 3-way tower speaker built for serious listeners. Dual 8″ woofers give deep, responsive bass, 6.5″ mid-woofers deliver warm, clear mids, and the AMT tweeter adds sparkling highs. Whether it’s music or movies, every detail comes through with accuracy and depth.

     

    Design Meets Function
    Compact yet commanding, the 661-SFM fits seamlessly in any room. Choose black or white satin, or go premium with piano lacquer or rosewood. Magnetic grilles provide a sleek, clean look while the modular cabinet ensures solid bass performance without adding bulk.

     

    Versatile Sound for Every Setup
    Use it as left/right mains, a center channel, or surround speakers—the 661-SFM is timbre-matched for a cohesive, immersive audio experience. Optional upgrades with RBH Reference drivers refine clarity and expand your soundstage even further.
