The TOA SR-WB4 is a dedicated wall mount bracket engineered for the SR-S4L line array speaker in the SR-S Series. Designed for fixed installation environments such as houses of worship, conference centers, auditoriums, and retail venues, this bracket positions the SR-S4L in an upright orientation directly against a wall surface, keeping sightlines clean and cabling managed. Where a single SR-WB4 handles one enclosure, integrators can expand the configuration to support a second SR-S4L by adding the optional SR-EP4 extension plate, giving system designers flexibility to scale vertical arrays without sourcing additional mounting hardware. The bracket ships with a complete fastener kit including speaker mounting screws and bracket assembling screws, reducing jobsite preparation time. Constructed from painted steel plate in a white finish, the SR-WB4 blends with architectural interiors typical of installed audio applications. For AV integrators specifying TOA SR-S Series systems, this bracket is the manufacturer-matched solution that ensures structural compatibility and maintains warranty compliance for wall-mounted deployments.
