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 125° 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.

The RS1201i is a 12-inch open-ceiling or surface-mount subwoofer tuned for maximum output and performance across the operating bandwidth. By incorporating a 12-inch treated fiber cone woofer and a treated cloth surround in a tuned and ported enclosure, this speaker delivers maximum low frequency response (32 Hz – 200 Hz, ± 10 dB, independently verified) and high SPL (113 dB). The SuperT™ is a special transformer that handles low subwoofer frequencies with very low losses. Mounting hardware includes high-quality UL listed cables and integrated SpeedClamp™ self-locking wire clamp for fast, easy and secure installation. For easy ordering, stocking and installation, the RS1201i includes a two-position tap switch for 70.7-, 100 volt and 4 ohm applications.

The RS42-EZ is a 4-inch, coaxial speaker with BroadBeam Ring^™ technology for consistently smooth high frequency sound, designed for open-ceiling applications. Hanging hardware includes galvanized steel cables and a built in hanging bracket with a screw on cover plate for fast, easy and secure installation. Unit may be hung or mounted direct-to-conduit via locking cover plate. The enclosure is constructed of injection molded ABS with glass fiber reinforcement for lasting durability in indoor or outdoor applications. The RS42-EZ speaker utilizes a 4 position ceramic terminal block input connector and a 6 position tap switch with transformer bypass position and has a 16 ohm impedance for easy daisy chaining in low voltage systems. The ceramic input terminal accepts up to 10 gauge plenum rated signal wire and includes thermal fuse. The RS42-EZ is suitable for use in voice alarm applications subject to EU regulations EN60849 and BS5839-8. Hanging hardware, weather plug, cover plate, and AC-RSEZ-HH-10 are included.
