SoundTube RS400i 4" Coaxial Open-Ceiling Pendant Speaker
The RS400i has a 4-inch polypropylene woofer and one 1.0 inch convex titanium tweeter with FerroFluid cooling mounted to a proprietary cast-aluminum baffle and heat sink. The two-way, ported speaker with an open-ceiling enclosure design that delivers effective low-end response (76 Hz) and 125º off-axis performance (2 to 10 kHz, independently verified). The speaker uses patented ZeroReflection™ enclosure technology for optimal sound reproduction and cabinet rigidity. SoundTube®'s proprietary BroadBeam® waveguide tweeter system delivers consistent high-performance audio coverage across the operating band-width. The RS400i speaker design incorporates a low-profile grille, proprietary motor-board and a six-position selectable tap switch for 25-, 70.7- and 100-volt applications with a transformer bypass position simplifies ordering and inventory tracking with transformer bypass position. Includes UL listed hanging hardware with cables and integrated SpeedClamp™ self-locking wire grip for fast, easy and secure installation. Euro-block connector and terminal weather boot are included.
