Summary: i got a pair of these bundled with the MS-RA50 header from fusion for my birthday, and i love them. i also bought the Bluetooth expansion, and the sound and loudness is great for my small 13 foot boat. the bass is of course a bit on the low side, but that's understandable for use on the sea.
Speakers don't hold up over time outdoors under a boat cover.

Summary: I didn't realize I was buying the same exact speakers I was replacing but they were being replaced because the cones disintegrated after a few years under a boat cover outdoors. Hopefully I will have a new boat before these cones are destroyed again.
