Boss Marine MR4.3W is a pair of speakers capable of diffusing audio without compromising on acoustic quality and power.
They can be installed both indoors and outdoors.
These loudspeakers are used in boating, where there is no bulkhead with the depth necessary to install common recessed speakers, as often happens in inflatable boats, or where you do not want to compromise the fiberglass structure.
However, being suitable for outdoor use, the MR4.3W are also suitable for use in other environments, such as in the garden or other outdoor activities.
