JL Audio 8W7AE-3(open box complete)

The W7AE embodies JL Audio's commitment to pushing the envelope of speaker technology. This Tenth Anniversary edition of JL Audio’s ultimate performance subwoofer features multiple patented technologies inherited from the previous W7 driver, but are distinguished by a few cosmetic differences to set it apart - most notably the Satin-Black Powdercoated Basket and Bright Anodized Surround Clamp Ring. Moreover, an OverRoll™ Surround, W-Cone technology and a Floating-Cone attach method are just a few of the JL Audio exclusive assets that set the W7AE above any other "high end" subwoofer driver currently on the market. These drivers have set the bar for drivers wanting to provide the deep transparent lows of a Sound Quality woofer and the hard hitting power of an SPL sub. The W7AE is able to provide its sublime sound quality and extreme output by efficiently dissipating thermal buildup and optimizing its staggering linear excursion.

Although the 8W7AE-3 Subwoofer can be driven with as little as 200 Watts, for best audio performance it is recommended to run an amplifier capable of between 400 - 500 Watts of continuous power per driver, like the JL Audio JX500/1D or JL Audio XD600/1v2. In addition, these subwoofers are optimized to operate in either a ported or sealed enclosures, needing 0.875 cubic feet of air space in a sealed box and 1.00 cubic foot in a ported/vented enclosure. (Specific dimensions and figures can be found in the user manual, linked further below.)

Every W7AE subwoofer is built to exacting quality standards in JL Audio's Miramar, Florida factory. Each of the four models is a completely original design from surround to back-plate (even the bolts and screws used in assembly have been purpose-designed and manufactured to our specifications). Its this attention to detail that delivers the JL Audio quality and performance we have all become accustomed to.

0.75 inches (19 mm) of Linear Excursion

By utilizing space wasted in conventional speakers, JL Audio's ground-breaking OverRoll™ Surround controls the W7's massive excursion without sacrificing precious cone area. In addition, the W-Cone™ assembly delivers astonishing cone stiffness with minimal mass. The shape also provides incredible torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits. Combined, these two technologies allow for the driver to achieve extraordinary linear excursion (Xmax), therefore providing that rich JL Audio bass.

Unparalleled Linearity and Accuracy

DMA is JL Audio’s proprietary Dynamic Motor Analysis system and is aimed at improving dynamic motor behavior. As a result of DMA optimization, W7AE motors remain linear in motor force over an extreme range of excursion and also maintain a highly stable fixed magnetic field in the gap over a wide power range. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass. Its main catalyst is the driver's Ultra-long Voice Coil, that allows extreme linear excursion, phenomenal power handling and control, control, control
