TOA TC-651M Reflex Horn Speaker TOA’s TC-651M Reflex Horn Speaker, rated at 50W, are designed for outdoor paging applications in houses of worship, factories, schools and more. The speaker features 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. TC-651M has been proven to provide more than 100 hours of operation at 50 W in continuous load test employing test signal that meets the International Electrotechnical Commission (IEC). High speaker efficiency has also been realized by minimizing the gap produced when the diaphragm bobbin is installed in the magnetic circuitry slit. TC-651M is designed to ensure high speech clarity and sound quality suitable for music reproduction. External hardware (screws, bolts, nuts) are made of stainless steel, and the mounting bracket and the horn itself are treated with a 50-micron thick powder paint coating. All of these factors combine to ensure the speaker’s excellent weatherproofing and corrosion resistance. In addition, the external horn flare is made of aluminum which is more shock-resistant than resin. TC-651M is equipped with an input impedance selector switch (3 steps for 100V line, and 4 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 settings.
