JL Audio’s award-winning lineup of powered subwoofer systems begins with proprietary subwoofer drivers and amplifier designs, precisely optimized for their intended physical envelopes and design goals. Because of this, they are not limited by which sub-assemblies are openly available on the world market. Instead, each system is fanatically engineered and precision-built in our Miramar, Florida factory to reflect their passion for spectacular audio and product quality.
