Fix a torn speaker cone?


If it is a woofer, you would probably fix it quite easy. If the speaker driver is used for both bass and midrange, you have a problem.
Fixing a speaker cone is depending on the material. If it is paper cone, it is very easy by using paper that you glue with wood glue (White water based glue) on to the cones rear side (for estetic reasons).
A midrange or bass/midrange driver is operating in frequencies where the cone starts to break up. Not torn apart, but the break up frequency is the frequency where the inner and outer part of the cone not longer follow each other in the same direction. These properties of a cone determine the sound of the speaker which is that type of speaker drivers "identity". Messing that identity up, you end up with a speaker that does not sound as the original one.
Remember that cross over network used to split up frequency ranges, not only are lowpass, bandpass, and highpass filter, but they also filter irregularities where the speaker driver is not longer providing a linear frequency response (Its characteristic sound).

If the cone is polypropylene, there isn't much glue that bite on that material.

How can replace the speaker the bass sound is broken


Dear Rob,
Really Thankful for the detailed description for the Speaker Repair.
It really helped me a lot. I have a unusual situation here with me. I have dissected the whole console and found the outer band of the speaker has just come off....have attached photos to make it clear. does the outer speaker cone will make a difference or i will have to replace the speakers itself.....when i checked pressing the speaker down and played the distortion had gone....but while playing without holding the distortion would come back....Hope you can help me in this situation....Thanks in Advance..... 714812a0-935e-4f95-922e-50c6ba281b9c.jpg 36e62701-6370-491a-a317-a11c69cc9525.jpg

I can't remove the speaker


Remove the protecting grill in front. Check if the cone is still connected to the rubber band. If not, remove the screws around the speaker. Open the casing itself. Do not forget the screw in the middle of the battery compartment. Remove the bottom cover. Disconnect the 2 wires on the speaker and take out the speaker. It will come out with the plastic protection around it. Looking at the cone now, push up the Carton cone and keep it in place by putting some tissue paper or small cloth underneath. Clean the cone first. Use some rubber cement on the outer edges of the cone and press the rubber back on the cone. Let it dry for an hour and then remove the tissue / cloth, so the cone goes back to its normal position.You can use some extra rubber (those pre-glued strips that you would use to fix a bicycle tire) to make it extra strong. Remount everything back in place and voila....it works again!If your cone is not damaged, the casing most probably does not seal good anymore. Tighten all screws a little more and use plastic electrical tape all around to seal all joints. The bass is produced inside the casing itself and pushed out via a horn. If it is not closed off well, your bass sounds grumpy.

HOW TO GLUE SPEAKER BACK TO BASKET


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!

REPAIR CONE TEAR IN 18"


If the tear is large, or the speaker cone is brittle because of age, you might be best off having the speaker completely reconed. There are companies that offer the service, or you can buy replacement cones and do it yourself.

For small tears (an inch or so long), you can glue a patch in place. I have used a piece of a paper coffee filter as a patch, and plain white Elmer's glue slightly thinned with water. Put the patch over the tear and use a small brush to spread a thin layer of glue over it. Give it a day to thoroughly dry and you should be set.

I have found this repair to be more effective on smaller speakers than on large woofers, though. The woofer cones are more mechanically active. But I patched a couple of 15-inch cones that had been punctured for a friend, and they are still playing after a year. So it can't hurt to try.

How to change door rubber on miele premier 300, can the front of machine be opened allowing to change the door rubber


I'm assuming you mean the flexible rubber between the door and the drum. Can it be replaced? The short answer is no! However...
I recently repaired a door rubber with a tear that caused the water to flood onto the floor. Here's how:
Yes, you can open the front to get to the door rubber however the rubber seal is glued to both the door and the inner drum lip.
You may have to tilt the machine on it's back to remove three screws from the underside of the front lip. (I forget if you need to take the water pump cover out as well but it wouldn't hurt to do so.) This allows the front panel (including door) to drop down a quarter inch or so and be eased out a little.
This allows *better* access to the drum rubber. To repair a tear - really the only reason you would want to do this - you need glue and some tape.
The door rubber is silicone and will stick with normal 'super glue'. However, bear in mind that these machines can do a wash up to 95C, which is hot enough to soften superglue.
I found a new version of superglue called Repair Extreme by Pattex that copes with temperatures up to 120C. It sets in about 5 minutes.
The glue needs to be flexible. Do not use epoxy resin.
I gave the glue some form by sticking a 10-15cm piece of duct tape - the silver shiny plastic tape plumbers use, readily available from any hardware and most supermarkets - to the *back* of the drum rubber. It's a tight squeeze to get your hands in there but it can be done.
Take the tension off the drum rubber by moving the front panel roughly back in place.
Then squeeze a generous amount of glue along the tear (about 3cm long on the bottom edge; a typical problem) to completely whet the edges to be joined.
Apply a little pressure to the location of the tear for a few minutes to help the glue hold fast. Leave the glue to set for at least half an hour before reassembly.
If you can source a replacement drum rubber the old one can basically be removed by force. A good cleaning and then a suitable glue could stick a new unit in place. However, if this is required, seriously consider buying a new unit. It is difficult to make a good seal that will not leak and may not be worth the effort in the first place.

Blown 12inch 1800 watt


first you have to carefully remove the center with razor knife careful not to cut into the cone.you can hot glue this back on when finished. doing this will expose the the two thin sound coils one is inside the other now carefully apply a thin layer of vasoline between the two that way there not touching each other directly. sometimes a piece of paper works to, but it gives a small vibration sound when finished. when done just glue the center back on

Busted cone (i think)


First try swapping the leads on your source, powering the left speaker with the right channel, and the right speaker with the left, if the problem follows, then the issue is with your source, and not the speaker.
If the cone is torn, then try to patch it, using some basic glue and several layers of tissue paper. White Glue, embed tissue paper in the glue, more glue,embed tissue paper in the glue, do this several times building up several layers. Guessing this is a standard paper cone...
Now if you are still having the issue, could be that the woofer is damaged. Look for a replacement.
