The Rockville RBL12VL is a dual 12-inch vented subwoofer enclosure built from 3/4-inch MDF and finished in durable bed liner. Each chamber gives a sub 2.25 cubic feet of air space, tuned to 42 Hz, with 20 inches of mounting depth and spring-loaded terminals. It suits people building a loud, deep bass setup in a truck bed or large cargo area who want a rugged pre-built box instead of a carpeted one. Against typical carpeted dual-12 boxes, it offers more air space and a tougher finish, but its 36-inch width and 22.5-inch depth demand a big space.
