    The JL Audio 13W7 embodies JL Audio’s commitment to pushing the envelope of speaker technology, with six patented technologies and a completely unique set of component parts. Each JL Audio 13W7 D1.5 model has been meticulously engineered to reproduce sub-bass with extreme fidelity at any volume level. The final product is a completely original design from surround to back-plate, requiring a significant tooling investment for all of the component parts. JL Audio 13W7 is a completely unique design and shares no major parts with its siblings. Each motor and each suspension system is specifically designed and tuned for each driver. If you consider the preceding, along with the fact that every part of every W7 (even the bolts and screws used to assemble the speaker), has been purpose-designed and manufactured to JL Audio’s specifications, you begin to get a firm idea of the JL commitment to this product.
