JL Audio is an independent, privately-held U.S. company active in the Home, Mobile, Powersports and Marine Audio markets. We focus on delivering unique engineering, superior quality and high-performance audio to our customers around the world. Behind all our efforts is a strong belief that great audio has real value, and that our customers can "tell the difference." Throughout JL Audio you will find people who love audio, take it very seriously and consider themselves fortunate to have a career in such a fun industry. The audio nuts found all over JL Audios facilities in Miramar, Florida and Phoenix, Arizona include recording engineers, former audio retailers, IASCA World Champions, installers, an incredibly experienced engineering staff, and people who are simply passionate about music and sharing this passion with others. Supporting our engineering efforts is an outstanding group of dedicated production and logistics professionals who make sure that JL Audio's factories in the U.S. and around the world maintain our high quality standards. Yes, you read that correctly--we proudly build the majority of our speakers right here in the U.S.A. Since most of our premium loudspeakers incorporate proprietary, patented technologies that require unique assembly techniques, we find that it is best to build them where we can directly control these critical processes. Today, all of our premium subwoofer drivers and all marine speakers are built in-house, along with most of our Enclosed Subwoofer Systems and every single Stealthbox product.
