The 13TW5v2 low-profile subwoofer driver has received awards from around the world for its breakthrough performance capabilities in impossibly tight spaces. In this sealed Truck PowerWedge™ subwoofer system, we harness the performance of this patented subwoofer driver to deliver amazing sub-bass performance from an enclosure that is only 7.25 in. (184 mm) deep at its base and 4.5 in. (114 mm) at the top. This enclosure design has been carefully engineered to the optimum sealed enclosure alignment for the 13TW5v2 and has been fine-tuned through extensive real-world listening. This subwoofer system is shipped wired, loaded and ready to connect via a five-way binding post terminal.
