The SoundTube RS500i-BK Hanging Pendant Speakers are premium, open-ceiling commercial loudspeakers designed to deliver exceptional coverage and clarity in high-ceiling environments. This two-way, ported system features a 5.25-inch polypropylene woofer with a durable butyl rubber surround and a 1.0-inch convex titanium tweeter equipped with FerroFluid cooling. SoundTube’s patented ZeroReflection enclosure technology optimizes cabinet rigidity for crisp, resonance-free bass response down to 61 Hz. Engineered with a proprietary BroadBeam waveguide system, these speakers project an ultra-wide 105-degree dispersion pattern, ensuring seamless edge-to-edge sound coverage that reduces the overall number of fixtures required in large installations like retail storefronts, restaurants, and airports.

Built to survive tough commercial applications, the system features a rugged, glass-fiber reinforced injection-molded ABS enclosure paired with a powder-coated steel grille. All internal components are heavily weatherized, earning UL 1480, CE, and Mil-Spec 810 certifications for both indoor and outdoor installations. For electrical versatility, the speaker includes an integrated 33-watt multi-tap transformer with an easy-access six-position switch that handles 25V, 70.7V, and 100V distributed audio runs, alongside an 8-ohm bypass mode for traditional low-impedance systems. Contractors benefit from the included UL-listed hanging hardware, featuring adjustable galvanized steel cables and a specialized SpeedClamp self-locking wire grip that slashes setup times during ceiling rigging.
