Our take on the JL Audio Stealthbox®

by Dominic Devito
JL Audio

Vehicle-specific enclosures with subs? Say what?

Instead of the usual sub in a box, the manufacturer creates a molded enclosure that fits perfectly into a convenient spot in your specific vehicle, housing a high-quality sub. Some enclosures even include a built-in amp, for the ultimate in stealth bass. The advantages? You don't lose much space (if any), your sub is perfectly matched to its enclosure, and your enclosure has a factory look that won't tell potential thieves you have an awesome sound system. Doesn't get better than that.

The JL Audio Stealthbox® custom-fit subwoofer delivers incredible bass in a package that takes up minimal space and blends in with your vehicle's interior. JL Audio designs Stealthboxes to fit in specific vehicles, then loads them with appropriate subwoofers for optimal performance. Pair the system with an appropriate amp and wiring for stellar concealed bass.

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 in the passenger side rear corner of the trunk of the 2005-up Ford Mustang Coupe, and replaces the factory subwoofer if one is present. It includes one W6v2 13.5" 4-ohm dual voice coil subwoofer from JL Audio, wired for 2-ohm mono impedance. A steel-mesh grille is included. Please check with us before purchasing by using the vehicle selector on our site, or calling an Advisor at 1-888-955-6000 to verify fit information.

JL Audio has rated the difficulty of this Stealthbox® installation as low. You should be able to install this enclosure if you have any experience with car audio.

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: One 13.5" JL Audio W6v2-D4 subwoofer is loaded in this sealed enclosure and wired as a 2Ω load at the enclosure's 5-way post speaker terminal.

  • 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.
  • Dual Voice Coil: The W6v2 woofer features dual 4-ohm voice coils. These voice coils are wired inside the box for a 2-ohm load at the Stealth Box's speaker terminal.

Crutchfield Customer Review (What's this?)
 
this is an amazing system. If you have a 05 to 09 mustang you should definitely think about getting this. you can keep your trunk and have awesome bass. the sound quality is the best ive heard, and ive had a 12w7 before. if you just want mindless bass, this will do it, but id prob go a different rout than this setup.

JL Audio Stealthbox®

Written By mechanicrob33, APO, Germany on Friday, August 14, 2009
 
I have always used JL Audio subs, but I was worried about only 1 single woofer. Let me tell you I saved trunk space and this joker is worth every penny. I am satisfied for 1 single woofer and I am use to running 3 15's but this joker gets busy and makes lots of noise. You will not be sorry!!
