Small Wonders of the Subwoofer World:

At JL Audio we have always been fascinated with designing outstanding small subwoofer drivers. The legendary 8W2’s of the 1980’s, the 8W6’s of the 1990’s and the current 8W7 are all emblematic of this pursuit of small woofer perfection. Another classic small driver design is the 6WØ, which proved that you could get true high-quality sub-bass from a 6.5-inch platform... something that many thought ridiculous or even foolish to attempt (until they heard one).

These new models demonstrate that our passion for engineering outstanding small drivers has not diminished. Whether you use them often or just in those cases where a larger subwoofer will not fit or work properly, it’s nice to know that these are full-fledged JL Audio subwoofers, engineered and built by people committed to pushing the envelope of small driver performance.

8W1v2:
All of the W1v2’s deliver affordable bass excellence thanks to technologies originally developed for our flagship W7 and W6v2 subwoofers. The newest member of the W1v2 family shares the same DNA.

Optimized for extremely compact enclosures and moderate power levels, the 8W1v2 opens up a whole new range of application options. Requiring a minuscule 0.25 to 0.38 cubic feet of box volume, this driver allows for the creation of high quality subwoofer performance in any application that is limited in space.

As with all JL Audio subwoofer drivers, development was guided by JL Audio’s proprietary DMA modeling system to deliver outstanding dynamic stability and low-distortion operation within their intended power envelope. A full complement of our patented woofer technologies are also on board to increase performance and reliability.

An injection-molded, metallic-finish polypropylene cone with an embossed metallic JL Audio logo provides a classy look, while a removable (and customizable) mounting flange trim ring receives grille-mesh inserts directly, without the need for additional grille hardware. (Grille mesh inserts are sold separately.)

6W3v3 & 8W3v3:
Just like the larger W3’s, these new models feature very long linear excursion capability to minimize distortion and increase output. They also offer higher power handling than the W1v2’s making them suitable for more demanding applications.

Available in single 4 ohm and 8 ohm versions, the 6W3v3 and 8W3v3 are superb performers at medium power levels in extremely compact sealed or ported enclosures. How compact? Well, how does 0.18 cubic feet sound? (6W3v3)... or 0.25 cubic feet? (8W3v3) Yes, the installation possibilities are pretty vast: under a seat, under a dash, inside a console... you name it.

Multiple patented technologies enhance performance and reliability while the DMA-optimized motor systems ensure dynamic stability and low-distortion operation.

A mineral-filled polypropylene upper cone body with a metallic JL Audio logo medallion provides a classy look consistent with our premium drivers, while a removable (and customizable) mounting flange trim ring receives grille-mesh inserts directly, without the need for additional grille hardware. (Grille mesh inserts are sold separately.)

I already talked to Manville Smith and Jason Sayan (of JL). They do NOT recommend these drivers in an enclosure. They're strictly for IB use. It won't break the speakers, but they'll sound awful.

 

EDIT: nevermind...I didn't see the scan on this page

 

Sorry, I thought you were posting up info about http://mobile.jlaudio.com/jlaudio_pages.php?page_id=215
Evolution slim 8" midbass driver.

 

well the link you have says that it is for door sub enclosures. Your saying its not.

Overview:
• Exceptional Infinite-Baffle Midbass Performance, Effective Down to 40 Hz
• High Power Handling, Long Excursion Design
• Shallow Mounting Depth
• Perfect for Newer Cars with Large Door Locations
• Dedicated Amplifier Channels with Active Filtering Recommended
• Precision-Built in U.S.A.

 

They are meant for Infinite-baffle use, no enclosures.

If we were to hack a chunk out of the back of the door enclosure, then they'd work fine, but that would caus a whole slew of new problems.

 

I have seen people modify the door enclosure to fit other subs on here. I wonder if its really all that bad. These things look sweet. If you dont want to modify at all I guess your right. I dont really know a lot about them.

 

While a woofer designed for an infinite-baffle application would typically assume the volume will be quite large, I wonder why JL Audio says Perfect for Newer Cars with Large Door Locations in their overview.

 

That's why I e-mailed them. They told me that IB was the only way they'd sound good. Then, they also told me my car doesn't have 8's in the doors but 7's. The door woofers are even slightly oversized compared to standard 8's. I think I'll contact them back to see if they'd give me some T/S parameters that I can plug into BassBox and see what I get.

 

Please post up the results if you get the T/S parameters.

They really should remove that statement from their overview if what they told you in the email response is true. It is misleading to say the least.

 

FINALLY DONE! What a project. started saturday, finally finished. installed CHE Kmember support with torque limiters, pulled bmr LCA's and greased bushings, installed Silver horse louvers. also installed the system, a profile 1200w 200w RMS 2 channel amp, 2 RF punch 2 subs, and soundgate locb.2. with 4 gauge power, and 12 gauge speaker wire.

What a pain in the *** running that 12 gauge through the door. I tried the heat gun method to make the subs fit, but gave up after several attempts to make them fit, so i cut it out, and fiberglassed it. a two day ordeal in its self. Work second shift, so i would do it after work. Finally put a second layer of fiberglass on tonight, and started reinstalling the door panels. Also installed dynamat extreme in the truck, rear deck lid, under rear seats, and door panels.

It sounds good, cant wait to get the car out of the garage and drive it again.

Thanks everyone for your help with all of my noob questions. you were all right, it wasnt as bad as i thought it would be.

Will these subwoofers fit the doors any better? Are there any direct replacements out yet? Have read nothing but good things about this company. Thanks

Nope, I've already tried them. As far as 6" subs go, they do sound good, though. The frame is far too wide to drop in without heating/molding the plastic enclosure. Then, the magnet is too wide once it's dropped in.

BTW, I never heard back from JL on the T/S parameters on those 8's above, either
I will say that the Kicker SSMB and RMB 8's will fit, but you won't be able to use the factory grills. I have the RMB's myself, and they work great.

 

I still suggest you all use the pioneer speakers that I put in the doors as shown in my earlier posts. They are proven, fit well and sound awesome!

 

Hey infinity, it's almost Labor day. can we find out the real name of The direct replacement door sub that shall not be mentioned? I'm about to rip apart my entire system and would like to replace these as well

 

The one guy just totally cut contact with me. That ****ed me off to no end. But, John Janowictz (sp?) of Acoustic Elegance (formerly Stryke Audio) is looking at it now. I've been in e-mail contact with him over the last couple of days, and I'm likely sending hime one of my factory drivers. The original that I wasn't going to talk about was Ultrasubs. I think he was more mouth than action.
Just for record, I've spoken to every buildhouse and custom builder in the US, and one in Canada (TC, Credence, Fi, Atomic, T3, Ultra, Eminence, Elemental, and now Stryke/AE) and no one wants to touch this. I'm severely disappointed. I know some of the Chinese buildhouses have the parts, but I don't have the means to purchase several thousand drivers, nor any way to communicate with them. I'm frustrated because I thought it would be easy.

Next drivers to try- CDT EF8 (I know it fits, but how well I'm unsure), and the Morel MW265 4 ohm.
I went ahead and tried the MTX 4500's that everyone said just "drop in". Well, they don't, and they aren't worth the modifications to do so.

 

Well, you definetly seem to have experience in this area so I will continue to let you do the testing for the door subs lol. I may just raise the wattage on them and treat them as a midbass driver Good luck with all your testing and thanks for everything. You've definelty been more than helpful to this forum

 

You can go to roughly 100-125 RMS on the factory drivers and be safe if you give them a highpass/subsonic at about 25hz. After that, they cry like little babies RIP passengers' side

 

Infinity,

I have the CDT EF8's. They went in pretty easy - a little massage with the heat gun to the portion of the enclosure that has the indentation only - there is enough depth otherwise and drilled 4 more holes in the EF8 frames to use all 8 mounting screws and in they went. I am running them on an MTX-282, which is a 140w/ch amp (peak @ 12v) - test sheet that came with it showed 95w rms@4ohm and it is plenty of power to drive them.

 

Well, they're in the queue to try. Thanks for the info.

Actually, they model VERY well in the enclosure size that we have. I'll bump these to "next" since I can snag them for about 50 each right now.
