The speaker cone and foam not held toghether halfway need to know what glue to use on aluminum square speaker

It sounds like your speaker surround blew away and separated from the speaker cone and/or housing. I'm in the process of fixing one my speakers by replacing the surround.

Generally, when this happens, you'll want to completely replace the speaker surround (the outer ring that allows the speaker coil and cone to travel in and out, usually made of rubber or foam rubber). This isn't necessarily super difficult, it just takes some time, skill and patience, if you want to avoid messing up the speaker and sound from it.


Inspect and repair your existing speaker:


1) Measure:

a) the diameter of your speaker cone (outer edge of the angled piece that goes inward toward the center coil) and the


b) diameter of the speaker housing (the metal "frame" part the speaker surround glues to, which is usually where the speaker mounting holes are located).


Note whether the area on the speaker cone where the surround connects to is flat or angled.


2) Ordering: You'll want to purchase the new speaker surround to match the similar material you've already got, as close as possible to the exact dimensions you measured in either flat or angled for mounting to the speaker cone.


SpeakerWorks.com tends to be a bit more expensive than others than can be found online, and they will normally have what you need. Their speaker surround repair kits normally come with instructions, surround, glue and a little brush. I found hunting around can save 50% or more.


3) Gluing: Get yourself some Aleene's Tacky Glue (online or in craft stores), and make sure you don't use too much or too little, applying in a uniform coat on one surface, then applying gentle pressure to get the surfaces to stick, and allow it to dry completely for 24 hours.


IMPORTANT: This can be tricky, so be patient, or you're buying a new speaker. If you don't feel comfortable, take it to be repaired properly.


Typically, you'll want to start gluing the new speaker surround to the outer portion of the speaker cone, either on the underside or inside, as it was with the prior surround. Make sure it's centered, applying just enough glue with a brush to insure it holds and you can still slide everything around slightly into proper position. Gently move the speaker in and out to make sure nothing is rubbing. Allow this to dry for a full 24 hours, and do NOT attempt to glue the surround to the housing until after the cone glue is completely dry.


Now, it's at least 24 hours later, you can do the same thing by applying an even layer of glue to the surround (or onto the frame) to complete the new surround replacement. Apply light pressure to make sure it's centered, again gently moving the speaker in and out to make sure nothing is rubbing. Allow this to dry for 24 hours, just like before.


I know, impatience makes this difficult, but then you don't want to be doing this all over again by trying to move too quickly. Worse yet, you can end up completely destroying your speaker cone.


The nice thing about that tacky glue is is holds well and allows you to position things for a while before it sets. Just remember to allow the proper drying time, which is always way longer than the dry glue you can see.

Remember to defer to a professional repairman if you do not feel comfortable doing these repairs yourself.

I hope this helps!

Hello
You have glued the lead wire to the speaker cone paper with silicone glue I assusmes. It will go for some time. Super glue is best. OK.

Hi,
Do not use any glues over the foam, it makes the foam get harder and probality of further damage leading speaker replacement. If you have a masking paper tape try to stick on torn area atleast to avoid further damage. But, all this attempts will give a loss on speaker's audio response. If you are not a big audio phile , you can manage doing it.

Hi, Jr.

I'm sorry, but glue will not fix this problem. When the rubber or foam edge of a speaker breaks down or deteriorates because of age, it becomes almost like dust, which is why it cracks and then breaks apart and falls away from the speaker. The only way to fix it (besides replacing the speaker) is to replace the edge, or "surround". At this link, http://www.simplyspeakers.com/All-Foam-Kits_c_118-1-3.html, you will find a kit that you can buy to repair your speaker for about $30. The standard 12" repair kit will work if you have an 'angle cone edge attach' type speaker (see the bottom of the page for a picture of what this means). This page, http://www.simplyspeakers.com/speaker-repair-foam-edge-replacement-instructions.html, will show you step by step how to use the kit to repair your speaker.

Good luck, and please remember to rate my help.
Thank you for the opportunity to help you.

well you can glue it. i have done it in the past. i used the gel super glue and it held up for about 3 yrs.

This is a very common problem and I don't know why companies still use foam.

The ring is called the "surround" and the problem is known as "surround rot".

There are 3 fixes.

Replace the entire driver. (most expensive)

Recone the driver (tear out the old cone + surround + spider and glue in a new one using the old basket).

Refoam the surround. (replace just the foam surround).

I know of one location in my hometown (Ottawa Ontario, that does re-foaming and people that do this are few and far between).

If you can find someone to refoam it go that route, failing that do a recone. A recone will last just as long as a new driver.

Hope this helps!

Cheers,

This speaker needs to be re-sorrounded. Look in your area for someone that re-cones speakers. While resurrounding speakers is not rockket science, it does take practice. Figure on $40 or so for resurrounding a 12-15" speaker.

you cant get a new cone only a new speaker or you car repair it i used super glue on a crack in one of my old subs and it held well

The speaker bezel can be removed in only two ways:

1) Somehow remove the grille in order to get a the screws which hold the bezel onto the cabinet. I tried to do this and couldn't get it to budge. Once I got the thing open I observed that Logitech used a LOT of glue to hold this thing together.

2) Drill holes THROUGH the grill above each of the 8 screws large enough so you can loosen the screws.

Once you get it open, you'll be shocked to discover what you thought was the subwoofer cone is actually A ROUND PIECE OF CARDBOARD fastened to the foam. The 4" driver is behind this fastened to a board halfway back pointing into the chamber containing the electronics.

You can get to the power transformer, but good luck removing it. The screws are nearly impossible to unfasten; more glue but more importantly incredibly awful access to the nut and screw (yes, a screw, not a bolt).

I wouldn't pay 5 bucks for this system. Luckily, I didn't.

A blown speaker needs the windings replaced and re-coned. If you have deteriorating foam\cardboard type edges you an use clear silicone caulk from any home improvement store to fix small tears or detererioration. Tears and such on a large scale will require re-building.
