My subwoofers cone keeps detaching why is this

Figure out if its a blown coil or damaged cone

1. Blown Coil:

The voice coil is the component, which amplifies the current run through the speakers. If you doubt that the coil is damaged, connect the terminals of the coil to a multimeter, and if there is no resistance detected, it could be because the coil is damaged.

2. Damaged Speaker Cone:

If there are no issues with the coil, the next possibility can be a damaged speaker cone, which can be detected easily. In normal condition, since the subwoofer is built on a suspension system, the cone is easy to move. Look for the following signs to understand that your speaker cone is damaged:

• If you could gently take the cover of the subwoofer off and check for the movement of the cone by gently pushing along the sides
• If the cone is rigid and does not move its indicator

Once you make sure that you have a blown subwoofer, the next step will be deciding on how to replace it. Imagine if your subwoofers can be fixed easily with minimal efforts within a set budget rather than buying a new one.



Then

1. Detaching the speakers:

Use a screwdriver to take the speakers from the place where it is mounted and take off the attached wires. After that, separate the surround and the frame by removing the glue on the frame edge by using a small knife or a sharp object like a tester edge. Be very careful when you do this because the frame edges can be damaged.

2. Separate the voice coil and speaker cone:

Using the same small knife or a tester edge, slowly take out the voice coil from the speaker cone. Cut all the terminal wires and keep the voice coil, speaker cone, and spider separately in place.

3. Fixing the new voice coil:

Clean the trapped dust particles in the voice coil gap carefully by using the compressed air. The voice coil is the piece of wire that is attached to the speaker cone, and that is responsible for amplifying the current, which is passed through the speakers. Remove the old voice coil and fix the new voice coil within the space if the problem is with the coil. Place the spider around the new voice coil, replace the spider and then the speaker cone in the middle. Don't forget to apply enough glue so that the cone doesn't come out. Let it dry for about 24 hours.

4. Fixing the speaker frame:

After it is dry, apply glue on the surround to fix the speaker frame and the cone in the right position. Now we are about to reassemble the components of the sub-woofer.

5. Fixing the wires:

Once all the components are put together in the right place, use a soldering iron to connect the old terminal wires with the new voice coil terminal wires, if the voice coil is replaced. If the new cone has no pre-attached wires, use small wires to the terminal wires, and then create small holes in the cone. Place the wires into the holes and connect them to the voice coil using the soldering iron.Now the connection is also reestablished.

yes. i know where you can get them but this information i keep to myself. contact me at [email protected] and will get you some new cones (cover only parts need to be reused)

Use a small flat screwdriver to lift the front grill from the sides.After detaching the grill,unscrew the plastic guard to have access to the speakers and then unscrew the speakers.

No other solution than replacing the entire driver. Contact Mission's US importer for parts cost and availability.

I would suggest to buy the entire cone speaker because the inner windings is harder to find or not available.
The cone speaker part number is: CR160058-01. Try contacting this website to find the cone speaker or you could find a cheaper speaker cone with the same dimensions and wattage.
I can also send you the service manual for this subwoofer.

The clunking noise could be the voice coil maxing out hitting its stop or a warped voice coil. How much power is going to the subwoofer. If it only happens when the high volume setting it and not at medium volume the subwoofer may not be able to handle the power. With your hand gently push the speaker cone back and release the cone so it can return to its rest state several times. Do you hear a scratching sound or feel any resistance? If you do your voice coil is damaged if not from physical means it could be from the voice coil overheating. If it is OK shake and rap on the subwoofer box and try to identify any loose parts which could be making noise.

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.

looks like your voice coils got detached from cone, possibly, due to previous overloading. 2 ways to fix it: if the cone could be detached from frame, you may be able to reach the joint between the voice coil and sew them up back with contact cement and sewing thread., second: replace those speakers with more powerful ones.
good luck,

sounds like one of the speakers are blown or the cone is deteriated/ripped.when turned up this causes yhe coil wires on the back of the cone to touch the casisng shrting it out.upgrade/replace standard speakers with new to rectify.thanks please rate me.

you need a strong glue that remind flexable
