Perfect sound to go with the perfect fit
JL Audio puts months of research and design into each Stealthbox® custom-fit subwoofer to ensure not only that it fits, but that it sounds better than any other custom enclosed system. First, JL Audio determines the ideal shape and mounting location for each enclosure, so that it looks like an original part of the vehicle it's designed for. Next, they mount each high-performance subwoofer so it delivers amazing firepower from within its unique enclosure, without sacrificing clarity or musical depth.

The fiberglass enclosure offers superior rigidity while allowing more interior volume, so the sub can turn out louder, deeper bass. JL Audio craftsmen then laminate, grind, join, and finish each Stealthbox® by hand. The end result: full-bodied, distortion-free bass from an impressively stealthy enclosure.

Enjoy enhanced, custom-fit sound
This Stealthbox® enclosure fits on top of the driver side cargo area trim panel of the 2003-up Hummer H2 SUV.

Perfect All Around Woofer

Written by: MICHAEL from California on January 28, 2008

Crutchfield Customer Review (What's this?)

Just installed the woofer in my 2007 H2 with Bose Premium sound system w/ factory touch screen Nav system. I used the PAC Audio AOEM-GM-24 line converter and a mono amp pushing about 1000 watts @ 2ohms. Its obviously overpowered for this woofer but it sounds great for the size. I'm a bass junky but didn't want to loose any cargo area so this was the perfect solution. It provides great low bass and excellent tight mid bass. If you looking for that real, real low bass you might want a bandbass however, i'm very impressed with the bass this puts out. It looks great and pretty easy to install with simple tools and the way it mounts its super sturdy and won't go anywhere even if your a hard core off roader. I would recommend this setup and would do it again. The best part is if you looking for a easy add on for your factory Bose system this integrates perfectly with the setup described above. If I could ask for anything more would be that the speaker be able to handle more power but I can always change the speaker later without any disassembly....

Features

Overview: JL Audio's Stealthbox subwoofer systems are designed to hide away in a specific vehicle. Please consult "Outfit My Car" to confirm compatibility with your vehicle.

Construction: Stealthboxes are hand-crafted from fiberglass and/or Advanced Molded Composite (AMC) materials. Fiberglass delivers a level of enclosure rigidity and dimensional stability not possible with other enclosure materials, allowing wall thickness to be reduced compared to a typical wood enclosure. This gives you more interior box volume for a given external volume. Fiberglass and AMC materials are very strong and can be molded into very complex shapes; giving JL Audio the ability to design your Stealthbox to fit perfectly into tight spots and minimize intrusion into your vehicle's useful space. Each Stealthbox is laminated, ground, joined, and finished by hand in the USA. Proprietary techniques and materials developed by JL Audio through years of fiberglass manufacturing experience ensure consistent quality and performance.

Woofer: A 12" JL Audio W6v2-D4 subwoofer is loaded in this enclosure and wired for a 2Ω load.

  • W-Cone: The JL Audio W6v2 subwoofer utilizes a W-Cone design, a unit-body cone assembly, that 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. In order to gain maximum stiffness, two lightweight mineral-filled polypropylene skins are bonded together at the perimeter and the center of the assembly. The lower skin's cross-section is shaped like a "W", and provides incredible rigidity when bonded to the dished upper skin.
  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W6v2 motors remain linear in motor force over a very long range of excursion, and also maintain a highly stable fixed magnetic field in the gap over a wide power range. The result is vastly reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.
  • Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
  • Engineered Lead-Wire System: The co-extruded lead wires work in conjunction with critically-engineered entry and exit support structures to achieve flawless high-excursion operation. The flying lead design does not compromise spider linearity or radial stability the way "woven in" lead wire designs do.
  • Progressive-Roll Spider: The large, progressive-roll spider provides precise control and motor/voice coil alignment without limiting excursion prematurely.
  • Ventilation: The woofer's large, diffused pole-vent works in conjunction with specifically engineered molded "NeckVents" in the lower cone body to remove hot air from the voice coil gap. This pole vent is located around the JL Audio badge at the rear of the speaker. The elevated frame design of the W6v2 delivers high-velocity air flow 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.
