600W RMS 12" Enclosed Subwoofer System
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. In the HO112-W6v3, the high power handling of the 12W6v3 Subwoofer, combined with its small enclosure requirements, results in a very compact subwoofer system that is capable of impressive output with moderate amplification.
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 W6v3 driver. This enclosure design has been carefully engineered to the optimum ported alignment for the 12W6v3, and has been fine-tuned through extensive real-world listening.
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. A steel mesh woofer grille insert can be purchased separately (Model: SGR-12W6v2/v3), if additional woofer protection is desired.
Finish: Dark gray, high-grade automotive carpet, with black carpet on woofer baffle. “JL AUDIO” is embroidered in silver on the side surface of the enclosure. Construction: CNC-Cut High-Grade MDF.
V-Groove MDF Construction
This advanced cabinet-building technique uses CNC-machining to create precise panel joints that make enclosure assembly more efficient and exact.
We begin with quality medium-density fiberboard, which is then machined on our CNC-controlled KOMO woodworking stations. These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.
Once the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a "wrap": a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.
The V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures. The quality of the MDF used in JL Audio systems is also vastly better than the typical “China-Grade MDF” used in the imported products.
High-Output (H.O.) Enclosure Design
Insanely powerful H.O. (High Output) systems deliver very high SPL while retaining excellent sound quality.
HO models use our patented, chamber-coupled port design. The slot-port wraps around the inner enclosure and terminates on the mounting plane of the woofer. This provides the necessary surface area and port length to maximize the performance of the driver, while also coupling the port output and direct woofer output to radiate together into the listening space.
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.
Elevated Frame Cooling
JL Audio's 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.
Many speakers employ venting techniques to enhance voice coil cooling. This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.
Our design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.
Another important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.
FCAM™ Floating Cone Attach Method
This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
JL Audio's patented FCAM™ technology is an innovative method of bonding the surround/cone assembly to the voice coil former/spider assembly. This feature helps ensure concentricity of the surround, spider and voice coil without torquing the suspension to achieve it. This allows for the inevitable, slight variations in production part dimensions without having them negatively impact the integrity of the suspension and coil-centering at high excursions.
PVAC - Pole-Vent Airflow Control
In high-powered Subwoofers, thermal management is essential.
The bullet-shaped structure inside the pole-vent directs airflow and increases air velocity to effectively reduce voice coil temperature, leading to improved fidelity and reliability.
Please note that the W6v2/W6v3 is a dual voice coil driver. BOTH voice coils must be connected to the amplifier (in series or parallel) for the speaker to operate properly. To accomplish this, each W6v2/W6v3 features a pair of main input connection push terminals and four voice coil configuration tab terminals. These are located behind the main input connectors and are used to interconnect the dual voice coils in one of two ways:
Diagram A: Series Connection (8 ohm nominal impedance per speaker) Use one jumper from "VC1-" to "VC2+".
Diagram B: Parallel Connection (2 ohm nominal impedance per speaker) Use two jumpers... one from "VC1-" to "VC2-"and one from "VC1+" to "VC2+". This is the way the speaker is configured at the factory.
After verifying that the tabs are properly configured using the supplied jumper(s), connect the amplifier's output wires to the W6v2's main input pushterminals and install the speaker into the enclosure.
Warning: Failure to properly connect the configuration tabs will result in no output and may damage the speaker.
Customizable Trim Ring
This removable ring can be painted to match the installation theme and directly receives JL Audio grille mesh inserts (sold separately).
This ABS trim ring is molded in black, but that doesn't mean it has to stay that way. By custom painting it, you can match your installation theme and create a personalized look.
Specifically-designed grille mesh inserts are available separately and fit into the inner diameter of the trim ring.
Helpful Tip: Installing the grille mesh inserts is much easier before mounting the woofer into the enclosure.
Engineered Lead-Wire System
Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.
Managing the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.
The biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's "stretching" behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.
While a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.
To overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.
