Enclosed Subwoofer System with Single 12W7AE-3 Subwoofer, Dark Gray / Black Carpet (1000 W, 3 ) - Ported Enclosure
JL Audio's patented High Output Enclosures are designed to deliver the ultimate high-performance bass experience with a rare combination of superb sound quality and awesome output.
JL Audio's patented, chamber-coupled port design (U.S. patent #6,625,292) wraps around the inner enclosure boundary and terminates just above the woofer, coupling the port output to the woofer's direct output. This also provides the necessary surface area and port length to maximize the performance of the W7AE driver.
This enclosure design has been carefully engineered to the optimum ported alignment for the 12W7AE-3 and has been fine-tuned through extensive real-world listening. The high power handling of the 12W7AE, combined with the efficiency of this subwoofer system, produce a devastating performance combination.
This subwoofer system is shipped wired, loaded and ready to connect via a five-way binding post terminal. While no grille is provided, the recessed mounting baffle provides some protection for the woofer.
The angled-back design saves precious cargo space by allowing the enclosure to fit tightly against the back of a vehicle's rear seat.
Finish: Dark gray, high-grade automotive carpet, with black carpet on woofer baffle. "JL AUDIO" is embroidered in silver on the top surface of the enclosure.
Construction: CNC-Cut High-Grade MDF
Recommended amplifier power: 400 - 1000WTechnology V-Groove MDF Construction
Nominal Impedance: 3
This advanced cabinet-building technique uses CNC-machining to create precise panel joints that make enclosure assembly more efficient and exact. High-Output (H.O.) Enclosure Design (U.S. Patent #6,625,292)
Insanely powerful H.O. (High Output) systems deliver very high SPL while retaining excellent sound quality. Dynamic Motor Analysis - DMA Optimized Motor
JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass. W-Cone (U.S. Patent #6,496,590)
The W-Cone is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass. The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits. Elevated Frame Cooling (U.S. Patent #6,219,431 & #6,229,902)
JL Audio's patented Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression. Floating Cone Attach Method - FCAM™ (U.S. Patent #6,501,844)
This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment. OverRoll™ Surround
By utilizing space wasted in conventional speakers, this ground-breaking innovation controls the W7's massive excursion without sacrificing precious cone area. Radially Cross-Drilled Pole-Piece (U.S. Patent #6,243,479)
This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil. This improves power handling and reduces power compression effects, leading to more linear performance. Engineered Lead-Wire System (U.S. Patent #7,356,157)
Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands. Built in U.S.A. with Global Components
JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.
