JL Audio, founded in 1975 by James Birch and Lucio Proni, began as a manufacturer specializing in car audio systems. The company started its journey in Miramar, Florida, where it gained a reputation for producing high-quality car audio speakers and subwoofers. Over the years, JL Audio expanded its expertise beyond automotive applications, venturing into the marine and home audio markets. Subwoofers are an essential part of any great audio system—stereo or multi-channel. They also are JL Audio's specialty. From the diminutive d108, to the awe-inspiring Gotham®, JL Audio’s powered subwoofers have received the highest accolades from audio reviewers and demanding audiophiles around the world. Within each model is a specifically engineered subwoofer driver and an optimised electronics package with unique JL Audio technologies. JL Audio’s engineering department is at the forefront of research into fundamental loudspeaker behaviour. They have developed proprietary electromagnetic and suspension analysis systems and invested heavily in state-of-the-art manufacturing and testing. This has produced subwoofer drivers widely considered as reference standards for linear displacement and dynamic stability. It has also resulted in numerous U.S. and International Patents issued for technologies that refine and extend the performance envelope of the dynamic driver. Through their continued research and development and unparalleled product range, JL Audio has solidified its reputation as a leader in the home audio subwoofer market.
