Is it possible to fix dented dust caps?

edited February 2013 in DIY, Mods & Tweaks
Suppose some idiot(such as I) got a screw driver too close to the dust cap and the resulting magntic field pulls the screw driver into the dust cap causing the entire thing to dent inwards. Is there a way to pull it back out?

    i've heard you can use a needle to make a small hole in the middle of it. Then take a paper clip type object to pull it out. Never done it myself though...

    Use the cardboard on an empty paper towel role and put it on top of the dome, then suck the air out with your mouth. It worked like a charm for me.

    Wrap some tape around your fingers and pull out the dent.

    The 6503 dust caps don't work with tape but the mid's in my 3.1's dust caps do work with their dust caps. 6503 are more cloth like then the mids in the 3.1's are more plastic like.

    I've done this and it worked like a charm. Needle-method should reserved for very stubborn dents. I'd sure like to see a jpg image of a girl using the paper-towel-roll vacuum method. Tape method may or may not work. Definitely worth a try though.

    a needle hole won't affect the performance? anything with "poke hole" and "speaker" in the same sentence scares me. . . probably just flashbacks to newbie threads about adding ports to speakers and such.

    Real easy... Use a vaccuum hose, make sure you partially cover the end of the hose with your fingers... you dont want to rip the dust cap off. Ive done it a few times with no problems. I definitely wouldnt poke a hole with a pin.

    I've gotten the vacuum method to work, and also blue tack on the tip of a pen (sort like the duct tape/ finger solution). Never tried the needle point...

    dang actually this method fixed the big ding. The smaller dent caused by some idiot(most likely me) who used glue(super glue, bad idea) has made the dent probably so hard it will never pop back into place.

    I have a tweeter dent that refuses to go away. The vacuum method was the only one that worked, but when I take the hose away, the dent takes about 60 seconds to come back. Darn! Don't the dome covers just twist off on some models? Is it possible to twist them off and then gently push the dome out from behind? The tweeter itself is still working fine.
    Alea jacta est!

    I have a dented 6511. I tried the tape method with no success. I will try the vacuum cleaner but the cap looks like it is cloth and air will pull through it.
    I like speakers that are bigger than a small refrigerator but smaller than a big refrigerator:D

    Could you post a pic of that tweeter? If you have removed it, could you also post a pic of the back?

    The needle works great for stubborn/ridged dust caps. I also notice no sound difference from the tiny pin hole, but I'm sure someone will debate me on that...

    It is actually a mid bass driver. I pulled it out but I ended up with a very slight tear in the dust cap.

    If it's a vented dust cap(some air can pass through), I don't see putting a tiny hole in it being a issue besides aesthetics. I can see a problem only if it's a sealed cap, and even then, it may not be noticeable.

    I used to use the paper clip trick on car audio subs back before everyone went to inverted/molded in dust caps. I figured if they were stupid enough to have them in the back of their car with crap rolling around to dent it, then a little whole in it wouldn't matter. It was a car sub...who cared. lol

    Of course, you can always put a tiny dab of glue on the pin hole and it will seal it back up.

    GAH! The word is DUCT not duck! It's tape that is used to secure two piece of DUCTing together. Usually the DUCTing is made or aluminum or galvanized steel hence the silver color of the DUCT tape so as to be aesthetically pleasing and maybe mask the presence of your handiwork.

    The tape, while good for many purposes, does surprisingly poorly at securing two water fowl together.

    That explains it ... I got very wet that day ... Thank you for clearing things up for me (I won't try it again).

    Yeah and it's a BRAND name not the actual name of the tape. Anything you see from Duck Tape has a registered trademark next to the "Duck".
