This is a compact, high intelligibility, reentrant type horn speaker.
	
The sturdy, weatherproof, all metal construction is ideal for indoor and outdoor use in industrial plants, warehouses, schools, construction sites, transportation terminals, and recreational areas.
	
Screw terminals make installation fast and easy, and there's a built-in, variable impedance selector switch for matching the speaker power requirements to a 25V or 70V constant-voltage line.
	
It's engineered to simplify installation (with a uniquely designed all-purpose mounting bracket) and field maintenance (with a self-aligning, field replaceable diaphragm)
	
The speaker and mounting bracket are handsomely finished in textured mocha enamel. Diameter is 11" with a depth of 10-1/2". A beam clamp is also available (BC1), as an option.
