Manufactured 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.
