JL Audio is an American audio manufacturer, founded in 1975 by James Birch and Lucio Proni—hence the name “JL.” Initially focused on home speaker kits, they quickly transitioned into car audio innovations, including one of the earliest car subwoofers, the 8W2. The brand is now widely celebrated for high-performance subwoofers, speakers, and amplifiers. All research, development, and manufacturing (including for marine and home AV lines) takes place in Miramar, Florida
