TOA TC Series Reflex Horn Speakers are designed for both indoor and outdoor paging applications, as well as for background music reproduction. The lineup includes four models rated at 15W (TC-615 and TC-615M) and 30W (TC-630 and TC-630M). The "M"-type models are designed for use in high-impedance (70V/100V lines) systems and standard models for low-impedance (TC-615/8Ω, TC-630/16Ω) systems. This wide product lineup permits selection of the ideal speaker for most applications.

TC Series speakers feature newly developed diaphragms employing special heat-resistant fibers impregnated with phenolic resin to prevent the diaphragm from absorbing moisture and changing shape. High speaker efficiency has also been realized by minimizing the gap produced when the diaphragm bobbin is installed in the magnetic circuitry slit. The aluminum foil bobbin also features excellent heat dissipation properties to resist high power inputs and ensure high speaker durability.

All speakers are designed to ensure high speech clarity and sound quality suitable for music reproduction. All external hardware (screws, bolts, nuts) are made of stainless steel, and the mounting bracket and the horn itself are treated with 50-micron thick powder paint coating which is about three times thicker than that of the conventional horns. All of these factors combine to ensure the speaker excellent weatherproofing and corrosion resistance. In addition, the external horn flare is made of aluminum that is more shockresistant than resin.

High-impedance models are 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 is also equipped with an OFF position to prevent speaker damage resulting from incorrect impedance setting.
