JL Audi0 W7AE Subwoofer Drivers
2011 marks the tenth anniversary of our flagship automotive subwoofer drivers. To commemorate this occasion, each W7 model is now offered in special "Anniversary Edition" (AE) trim, which includes a satin black frame finish, a bright-anodized trim ring and special badging.
Once you begin to analyze the technology and the performance
envelope of a W7AE, you realize that these are much more than just 'big
SPL speakers'. 2011 marks the tenth anniversary of our flagship automotive subwoofer drivers. To commemorate this occasion, each W7 model is now offered in special "Anniversary Edition" (AE) trim, which includes a satin black frame finish, a bright-anodized trim ring and special badging.
The W7AE 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 W7AE model has been meticulously engineered to reproduce sub-bass with extreme fidelity at any volume level.
It wouldn't be enough for this speaker to sound great or be loud, it had to do both... at the same time. Meeting this goal required us to develop a deeper understanding of the inner behavior of speakers, new and proprietary modeling systems and six new, patented technologies.
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).
