Sony's Slim Series subwoofers dish out powerful low-frequency performance, and their compact profile enables you to add bass to the tight confines of smaller vehicles. Find a suitable box or build a custom enclosure to fit your needs, and let Sony's advanced technology turn those areas behind or under your seats into premium bass outposts. The XS-L12S 12" subwoofer incorporates the superior rigidity of polypropylene into its unique five-sided cone. The pentagonal design also helps reduce standing waves found in round subwoofers, eliminating potential distortion which can harm your bass output. A tough rubber surround allows the sub to take a pounding and stay under control. No worries about power � the XS-L12S can handle 380 watts RMS without fear of a meltdown. Gold-plated, 5-way binding posts offer a convenient, super-efficient connection to your amplifier.
