| W7 Subwoofer Drivers by JL audio "The W7 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 W7 model has been meticulously engineered to reproduce sub-bass with extreme fidelity at any volume level." "At first glance, you may only see a rather massive woofer, but as you begin to analyze the technology and the performance envelope of a W7, you will realize that they are much more than just another big SPL speaker. For us, designing a pure SPL speaker, with no regard to sound quality, would have presented a far lesser challenge than the one we chose to undertake with the W7 project. The goal was to design subwoofer drivers that deliver immense output with an extremely high level of fidelity." "It wouldn't be enough for the speaker to sound great or be loud, it had to do both. This goal required us to develop a deeper understanding of the inner behavior of speakers, new and proprietary modeling systems and six new, patented or patent-pending technologies. We could have made a good-sounding, big speaker without going through any of this effort, but we chose to stretch our limits and devote the time and resources necessary to create a real breakthrough." "Along the way, we encountered many obstacles and dead ends which affected our design direction. We considered countless solution sets and discovered, through modeling, experimentation and dozens of prototype generations, which ones would help achieve our goal (and which would not)." "The final product is a completely original design from surround to back-plate, requiring a significant tooling investment for all of the component parts. Each W7 (8-inch version to 13.5-inch version) 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 our specifications, you begin to get a firm idea of our commitment to this product. All W7 subwoofers are built to exacting quality standards in our Miramar, Florida factory." Available Models: 8W7 10W7 12W7 13W7 |
