The most compact FUSION stereo system yet, the MS-RA55 delivers clear and dynamic sound reproduction in a marinized, space-saving chassis.

With Bluetooth audio streaming, users can stream music from any compatible device to the MS-RA55, allowing boaters to enjoy their favourite streaming service apps.

Featuring a sleek front face finish with a shallow-mount case design, the new low-profile MS-RA55 design allows for easy installation on small boats, tenders and personal watercraft, adding the highest quality sound to vessels that previously lacked the space for a full-feature stereo system.
