The WMP40M are protective covers for the mounting and connection plates of the ATEO4M loudspeakers. These protective covers are made of synthetic rubber. They are used as a protective cover to protect the speakers during interior painting, preventing paint from reaching them.

Due to their durable construction, they can also be used to protect wall plates in outdoor applications when speakers are removed for the off-season while the wall plates remain installed. This prevents dirt and moisture from reaching critical parts.
