TOA SC-651 Paging Horn Speaker

TOA's SC-651 Paging Horn Speaker, rated at 50W, is designed especially for outdoor applications. The SC-651 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. High speaker efficiency has also been realized by minimizing the gap produced when the diaphragm bobbin is installed in the magnetic circuitry slit. The SC-651 features TOA's unique oval shape, which enhances excellent speech clarity.

The mounting bracket, bracket holder and the horn flare are treated with 50-micron thick powder paint coating, which is about three times thicker than that of the conventional horns and external hardware (screws, bolts, nuts) are made of stainless steel. 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.

Each model is a double re-entrant horn with compression driver for high sensitivity and a lightweight aluminum enclosure. The loud-speaker diaphragm is heat and moisture-resistant to prevent deformation and extend operation. The SC Series are also IP-65 standards compliant for dust and moisture-resistance with a wide operating temperature range from -4° F to 130° F. The SC Series Paging Horn Speakers are backed with a five-year warranty.

Note: For outdoor installation, it is recommended that they are installed under roofs, eaves, or in other locations not directly exposed to rain or snow.
