Roswell 12in Black Marine Subwoofer 500W RMS

The Roswell RMA 12in marine subwoofer has a genuinely versatile design, one that performs well in an infinite baffle configuration as well as being well suited to sealed and ported enclosures. That flexibility means it fits into whatever enclosure setup already exists on a boat rather than forcing a specific box design. Not every marine sub can make that claim across all three common enclosure types.

This sub handles 500 watts RMS with excellent low-end extension, delivering real bass output rather than the thin, boomy low end a lesser marine sub tends to produce. All of that performance is packed into a durable marine-grade plastic housing. That housing is built to shrug off the humidity and vibration a subwoofer faces mounted on a boat.

It needs just over 5 inches of mounting depth, a modest requirement that opens up installation locations a deeper sub simply couldn't fit into. Rated at 1000 watts peak power, this 12in version gives real headroom above its RMS rating. That headroom absorbs the occasional demanding passage in a track without the sub straining to keep up.
