Combination type reflex horn speakers provide by Olefins trade corporation in Bangladesh. Stainless steel brackets and hardware, and powder-coated horn. Also Shock-resistant aluminium oval horn. Horn speaker is suitable for School, college, prayer hall, outdoor, factory and any place where sound level is upper than 110 dB.
TOA SC series paging horn speakers provide intelligible voice paging and tone signaling for indoor and outdoor sound system applications. Fully weather-resistant for reliable operation in demanding environmental conditions, SC Series models are available with a choice of power ratings from 10W to 50W. High impedance models include SC-610T (10W), SC-615T (15W) and SC-630T (30W), each with a built-in 25 V / 70.7 V transformer with external screwdriver-adjustable power taps. Low impedance models include SC-610 (10W, 8 ohm), SC-615 (15W, 8 ohm), SC-630 (30W, 8 ohm) and SC-651 (50W, 16 ohm). The SC Series are easy to install in wall, pole or ceiling-mount applications and include corrosion-resistant stainless-steel mounting hardware. The SC Series models are also designed for intercom talk-back applications requiring dual operation as both a microphone and speaker.
The new SC Series Paging Horn Speakers are direct replacements for the now discontinued TC Series products. Also see the new CS Series Wide-Range Paging Speakers.
* 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.
