Our take on the Sony Xplōd™ XS-GTX121LS by Crutchfield's Jo Greene
Sony designed the XS-GTX121LS sub enclosure to deliver space-saving bass in your compact car or truck. The enclosure houses an explosive 12" sub with a unique five-sided design that helps the cone stay stiff while reducing standing waves that can diminish your bass output. The sub's sturdy internal construction gives you strong performance over the long haul.
This sealed enclosure produces tight, accurate bass, and its medium-density fiberboard construction means this box can stand strong when the bass gets heavy. Industrial-grade black carpet protects your trunk from nicks and scratches. This loaded enclosure handles serious power — up to 300 watts RMS — so you can throw down with confidence. The gold-plated binding post terminals accept just about any speaker connector on the planet.
Pretty good for average Boomers, but not for your serious thumpers. But over all it's good
