The RECON 10-inch subwoofer is optimized for infinite baffle/free air applications and designed to achieve maximum performance without requiring a tuned enclosure. Perfect for mounting under a seat and utilizing the cargo area as it's enclosure. The RECON subwoofers utilize a Nylas composite frame, with an injection-molded composite cone and the Wet Sounds' signature Santoprene Spider. Bass made simple. Availabe with a Silver or Black RECON Grill or a White XW Grill to match any application.* RGB Grill Sub Kit will not work with Recon Grills. If you'd like the RGB Sub Kit, REVO sub grills will need to be used.
