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'.
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.
