The Reflex Horn Speaker, rated at 30W, shall be designed for both indoor and outdoor paging applications, as well as for background music reproduction. The model designed for use in high-impedance (70V/100V lines) system and standard model for low-impedance 16 ohms system shall be available. The speaker shall feature newly developed diaphragms employing special heat-resistant polyimide film to prevent the diaphragm from absorbing moisture and changing shape, as well as to improve the low frequency characteristics. High speaker efficiency shall have also been realized by minimizing the gap produced when the diaphragm bobbin is installed in the magnetic circuitry slit. The speaker shall be designed to ensure high speech clarity and sound quality suitable for music reproduction. External hardware (screws, bolts, nuts) shall be made of stainless steel, and the mounting bracket and the horn itself shall be treated with 50-micron thick powder paint coating which is about three times thicker than that of the conventional horns. All of these factors shall combine to ensure the speaker's excellent weatherproofing and corrosion resistance. In addition, the external horn flare shall be made of aluminum that is more shock-resistant than resin.
High-impedance model shall be equipped with an input impedance selector switch (4 steps for 100V line, and 5 steps for 70V line) which facilitates the ease of impedance settings without requiring disassembly. The switch shall be also equipped with an OFF position to prevent speaker damage resulting from incorrect impedance setting.
