Boss Marine MR4.3W pair of external and internal speakers

MR4-3W Boss Marine

Powerful 3-way MR4.3W Boss Marine speakers that can be installed both indoors and outdoors, with a peak power of 200 watts.


"Boss Marine" MR4.3W is a pair of speakers capable of delivering sound without compromise in acoustic quality and power.
They can be installed indoors or outdoors.

These loudspeakers are used in the nautical sector, where there is no bulkhead with the necessary depth to install the common built-in speakers, as often happens in inflatable boats, or where the fibreglass structure is not to be compromised.

However, since the MR4.3W is suitable for outdoor use, it is also suitable for use in other areas, such as in the garden or other outdoor activities.
