titan pitre lol idk why this doesn’t have thousands of likes !

Albert Magallon Thanks for the feedback!

Simply Speakers where do you recommend I order the repair kit?

Simply Speakers thanks!!

Came in to see if there was an answer for this. thanks.

Thanks for the tips! :)

Thank you!

Perfect!

That's a great idea!

Great, thanks!

Great news!

You can use double sided peel and stick foam tape, or you can use the MI-3035 adhesive in our kit to bond the parts.

Thanks!

Use some wadded up paper towels under the cone to help hole it up. :)

Yes, they are tight. Contact us through our website and we will send you the link for installing the o-rings. Thanks!

Not needed. Follow video and you should be fine.

Your best bet is to lift and hold the cone with wadded up paper towels behind the cone.

W7 subs are centered on final install using the metal o-rings.

The surround will likely need to be replaced. If you find it is bad, we have the kits, so no worries. Happy to help if needed. Thanks!

Sorry, no coils for these.

Glad you liked it!

We use the MI-3035 adhesive for this repair. Visit www.simplyspeakers.com

The speaker must be removed from the cabinet to do the repair. Thanks!

You can use a couple of bunched up washcloths or paper towels under the cones to prop them up.

@@simplyspeakers awesome, thank you for replying.

Our MI-3035 adhesive and it is included with the kit.

Place a few wadded up paper towels under the cone to hold it up until the adhesive cures.

@@simplyspeakers gotcha cool, thanks! I bought the kit for my w7 10” from you guys. Can’t wait to get the boom back in my trunk!

Thanks. Not sure since we always get them in the shop and the foams are pretty deteriorated. Might need to email a photo of that unit to us so we can see what options you have.

I just tackled this repair because my foam had a small rip in it, however, the foam was not deteriorated at all. I first cut the foam with a utility knife as close to where the two cones are glued together as possible. I did so giving myself a bit of space so I wouldn't risk nicking the plastic cones with the blade accidentally. I then used the heat-gun to heat up the glue and foam around the perimeter of the woofer, and then used the utility knife to cut the foam between the two cones enough so that I could get my finger between the two. Then, while applying a bit more heat in front of my finger as I worked around the perimeter, I was able to heat the glue and foam enough to separate the two layers. The foam did not split, rather, the glue loosened from the top cap, and the foam stayed on the bottom cap. Once the top cap was removed, I then used more heat, got underneath the foam (which was easy once the top cap was removed, it appears JL used glue on the bottom cap more towards the outside of the cap rather than the inside), and worked the foam around and removed it as one solid ring piece. I then had to use alcohol to remove the glue residue left over.

We like to let the glue set up for several hours. Overnight is best. You might try the fiberglass resin to seal the cracked part of the cone. That should work great!

@@simplyspeakers thank you so much 😊

We like to give them a few hours setup time, just to be safe.

@@simplyspeakers lol ok, i mean: how long do you have to hold the cone raised by your hand :)

There is only one W7 surround for each size. subwoofer. 8", 10", 12" and 13".

Oh ok, I thought there may have been an improved or modified design. I wish there was a rubber surround option.

For the W7 series, all the surrounds are the same design, just different sizes.

You can clean excess glue using lacquer thinner or acetone.

Thanks I'll go ahead and give it a try 🤙@@simplyspeakers

We sell the kits. We ship from our warehouse in St. Petersburg, FL

But i did notice that the foam is coming of as well

You can usually re glue the surround as long is not starting to deteriorate.

Depends on the temperature, humidity, etc. Best bet is to let them sit overnight (at least) before putting them back into service. Hope this helps!

No, the JLW7 surrounds are held in place around the outer rim with the metal trim ring.

Dab of glue should be fine!

Thank you so much!! You guys are amazing! This is a great how to vid, and your guys foam and service is amazing! Id highly recommend anyone who's thinking about buying from these guys to do it 😊😊❤️

I messaged JL that and was told no difference. The only difference is they added AE emblem for the 10th anniversary.

We are using the MI-3035 adhesive which is included with the repair kit..

Can't shim on the W7 subs. Design does not allow for shimming. The surrounds is attached to the outside frame with a mechanical metal ring that allows movement and to center the assembly as needed.

David Rizzotto Thanks! We are in St. Petersburg, Florida.

Make your own then and be prepared for a bunch of questions and complaints from your viewers. You must know it all because his 24 minute video seemed like 5 minutes to me, very informative and thorough.
