The Polk DB1042DVC 10" Dual 4-Ohm Voice Coil Subwoofer with Marine Certification is a high-quality car subwoofer designed by Polk Audio. With a thunderous sonic output and powerful bass, this subwoofer delivers deep and rich sound. Its slimmed-down form factor allows for space-saving design options, while its IP65 rated construction ensures durability against dirt and water. The subwoofer features a waterproof Santoprene surround and a patented Dynamic Balance technology for a clean and full-range sound experience. With 350W RMS power and a 4-ohm impedance, this Polk subwoofer is a great addition to any car audio system.

I bought these from a downsizing Amazon distributor.   These are new and unused, but the boxes may be a little beaten up or have stickers on them, etc.  You will get a new, unused speaker with all the other things that come in the box.
