Our patented 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.
Summary: This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment. 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.
Detailed Information: 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. Summary: Information on connecting the dual voice coils using the Terminal Jumper System. BOTH voice coils must be connected to the amplifier in series or parallel for the speaker to operate properly. These are located behind the main input connectors and are used to interconnect the dual voice coils in one of two ways:.
Diagram B: Parallel Connection 2 ohm nominal impedance per speaker Use two jumpers 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. Summary: Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.
Detailed Information: 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. Summary: This removable ring can be painted to match the installation theme and directly receives JL Audio grille mesh inserts sold separately.
Detailed Information: 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. Anyways, to answer your question; No other company is going to stock a direct replacement with original parts for the drivers. The original W6 series used "off-the-shelf" parts, meaning it would be possible for a company to use identical parts to build a recone kit that is identical to the original parts.
The newer W6v2 does not use all "off the shelf" parts, so another company would not be able to provide an recone kit that is identical to the original parts. Depending on the different driver dimensions voice coil diameter, gap width, spider landing diameter, etc , another company such as Fi might be able to recone the driver for you which would give you an operational subwoofer Actually it was dual 4 ohms voice coil, not 2 ohms, but when I measured the coil resistance it reads 3.
Sorry my bad. I hate seeing my JL 12W6 sitting in the corner.. If Fi can replace the magnet and save the basket for recoil and recone kit that would probably work fine and close to Fi specs. The spider and cones will be useless anyways since it will be torn apart. Thanks for the info. I'm not even sure why you would try to salvage the basket.
By the time you replace the motor and softparts, you might as well just buy a new driver. The basket may limit their ability to fit different parts based on dimensions, clearances and attachment to the motor. If you are going to go to the length of having them replace the motor as well as softparts, just buy a new driver.
Even if they could use the JL basket, by the time you paid for shipping both ways, new softparts and motor, you would probably be money ahead to just buy a Fi driver. I believe if you send the driver to JL they can recone it for you, but it's normally very expensive.
And they don't sell any recone kits because I believe when they recone a driver they simply stick it back on the assembly line, have the softparts put in then send it back to you. It still plays but sounds shitty on high volume.
Just shipping alone will cost me an arm and a leg. I was thinking of getting a W7 reconed and I contacted fixmyspeaker and they told me they will only use the motor and the rest they will replace including basket.
