Description
TOA SC-651 Paging Horn Speaker 50 W 16Ω Mounting Bracket Included
Product Details
The TOA SC-651 is the largest horn in this group: 50 W through an oval aluminum flare 16.93 inches across, built for long throw across big open sites.
Note the impedance — this one is 16 ohms, not the 8 ohms of the smaller SC horns, so check the amplifier's minimum load before wiring a run of them. The compression driver uses a polyimide diaphragm to take the 50 W continuously, and frequency response is 250 Hz to 6 kHz: narrower at the top than the small horns, traded for output and reach. A steel bracket allows wall, pole or ceiling mounting.
The housing is rated IP65 against dust and water: an aluminum horn flare with powder coating, an ABS reflector and rear cover, and stainless steel bracket and fixings, which is what lets it live outdoors without the hardware rusting into the wall. A mounting bracket is supplied with the speaker.
