Woofer dust cap repair advice, HELP

Some woofers have vented pole pieces with no screening in the vent hole. If such is the case, you can stick a long pencil through the hole in the back and use the soft eraser to try and massage the dents in the dust cap back into place very gradually.

It this isn't feasible, i would try using some masking tape wrapped around your fingers and taped back onto itself. This will allow you to apply as much pressure as you need to in order to get the tape to adhere to the cap and at the same time, allow you to vary how much tension you put on the cap while pulling the dent out. You can then use your other hand to stabilize the cone so that you're not pulling on it sideways, etc... The masking tape may be sticky enough to grab the cone but it will break loose if you pull too hard. This minimizes the potential to damage the driver and at the same time, won't leave any type of residue behind.

The use of some type of small suction pump or a "leaky vacuum attachment" may also work if you can find the right size and shape attachment. If you try to use a standard vacuum, good luck. I'm sure that it can be done, but it sounds a little risky.

As a side note, i would not worry about this too much. On most woofers, the dust cap is not very critical. This becomes more critical as the driver is used to reproduce higher frequencies. Sean

PS... I bet that someone's blood pressure about blew their eyeballs out of their sockets when they saw this. How much smoke poured out of your ears??? Is the child still alive???

For driver speaker repair Orange County speaker repair is great and reasonably priced. Jallen

I tried using masking tape to pull the cap out and it did not stick to the cap. I'm not sure what the cap is made of but it looks like handmade paper. For that reason I'm a little leary using a full sized vacuum. I tried a little hand held Dirt Devil thing but it didn't have enough sucton.

Unfortunately my kids are old enough that we no longer have the breast pump suggested earlier. I think Marakanetz just wanted to say 'breast.' : )

The smartest thing for me to do would be contact Kharma and see what they might suggest but I would still appreciate any suggestions.

I spoke to a speaker manufacturer's customer service department about this issue just last week. They advised that they had done alot of testing on damaged drivers and it was not worth replacing it unless the dent impeded the movement of the cone. In fact, they told me that they had a speaker in their listening room damaged the way yours was when an elementary school class had come for a factory tour, and they had allowed it to remain in their room as is. They also advised that people frequently make matters worse when they use tape to try and fix the dent. Keep the grille cover on so you don't have to be reminded of the dent.

I have had very good luck pulling out dented dust caps using a pin or a needle. Just poke it through the dust cap next to the dent and manipulate it so as to press out the dent from the inside. When you withdraw the pin there will be a tiny hole where the pin was. If this bothers you, plug it with a speck of glue.
