10" Subwoofer Ultramarine - Silver
Polk's marine subwoofers have always been known for intelligent design, impressive sound, and weather resistance. The UMS108 sub continues this tradition with solid construction that stands up to the elements.
The UMS108 is made to kick out deep bass under challenging conditions. Its mica-reinforced polypropylene cone handles up to 350 watts RMS, and the stiffness of the cast aluminum basket gives you the clean, hard-hitting performance you expect from Polk. This sub's air-suspension design makes it suitable for installation in any panel of your boat without the need for an enclosure.
