JL Audio Unleashes The W7 Subwoofers

Miramar, Florida—October 15, 2001—JL Audio, known throughout the world for their award-winning auto sound loudspeaker systems and amplifiers, is now shipping the W7 Series subwoofers to JL Audio specialty retailers around the U.S.

Since the debut of the W7 Series to the world at CES 2001, they have become the most talked about and anxiously awaited products JL Audio has ever introduced. The unique design and innovative mounting feature added to the mystery creating a multitude of theories on how to actually mount this massive speaker!

Now available, the W7 Series is the result of seven years of research and development led by JL Audio’s CEO and Chief Engineer Lucio Proni. His design goals for these models were simple—to break new ground in terms of fidelity and output capability, within the same product. The execution was far from simple, requiring the development of six new patented or patent-pending technologies that represent significant advances in driver design.

CEO and Chief Engineer Lucio Proni says: "The W7 project was conceived to push subwoofer driver technology to an entirely new level. We weren't content with making an incremental improvement, we were looking for a major leap. After years of work overcoming obstacles and developing new technologies for the products, we've arrived at our destination — three drivers with unsurpassed linearity and fidelity."

According to Manville Smith, V.P. of Marketing & Technical Services, the company is extremely excited about releasing the W7's: “For years, the W7's have been shrouded in secrecy. Now that the products are hitting the streets, we're thrilled that car audio fanatics are going to hear the products and discover what we at JL Audio have already experienced… A pure, effortless and absolutely faithful sound, at any volume level."

The W7 Series consists of three subwoofer models, a 10-inch, 12-inch and 13.5-inch woofer. Each embodies similar design and technology features such as:

Extreme Excursion Capability: 10W7: 0.90 inches, 12W7: 1.15 inches, 13W7: 1.25 inches (all measurements one-way linear, strict voice coil overhang measurement with no correction factors applied).

DMA-Optimized Motor Systems: The result of JL Audio's intense research into dynamic electro-magnetic behavior, this technology results in the most dynamically stable and linear motor systems ever produced by JL Audio. OverRoll™ Surround: A patented technology that allows for a large surround without sacrificing precious cone area. W-Cone™ A patent-pending, unit-body assembly consisting of two bonded polypropylene skins that delivers astonishing cone-stiffness with less mass than metal or composite materials.

Floating-Cone™Attach Method, a patent-pending technology that ensures proper surround/cone geometry for better excursion control and dynamic voice coil alignment. Plateau-Reinforced Spider Attachment: a derivative of JL Audio’s famous VRC technology, this design relieves stress from the spider material at extreme excursion levels. Patented cooling system: Combining JL Audio's radially cross-drilled pole design with a new elevated frame design that provides high-velocity air-flow to the voice coil and the top surface of the top-plate.

The W7 Series subwoofers push the performance envelope of high-excursion driver design to levels never achieved before. They are available now through JL Audio’s custom auto sound retailers.
