La voce 184.03 18” subwoofer driver

I have an almost new subwoofer that I ordered by mistake. The woofer is awesome but it is 8 ohm and I need 4 ohm. I have the original carton it came in. No speaker enclosure included. This is a literally as new as you’ll find a subwoofer on the marketplace sold as used. Located in mission Viejo. $240
