The RH40 Horn speaker is a rectangular horn that's built around the outdoors.
This horn is weatherproof and perfect as part of a 100 volt line system where public address is key and allowing people to hear you is important. Being part of a 100v line system means that multiple speakers can be 'daisy chained' together over a large distance allowing for maximum speaker coverage.
This is perfect for race tracks and motorsport circuits plus crowd lines and entertainment arenas on showgrounds.
