TOA / BS-22B Facility Speaker

The TOA BS-22B is a high-impedance compact speaker with a painted, sealed enclosure and a waterproof resin cone speaker, making it dustproof and waterproof to IP65. It can be installed outdoors in a location where it will not be directly exposed to rainwater, such as under an eave. The punched net and angles are both powder-coated, and the screws are made of stainless steel, making it highly corrosion-resistant.
