How to "unpop" a Speaker





Introduction: How to "unpop" a Speaker

have you ever popped in the centre bit of a speaker and wanted to no how to get it back out? well here's the answer

there are 3 ways to do this

Step 1: First Way

the first way you can do this is simply by using your mouth

all you do is put your mouth round the centre and suck in as hard as you can (this may take a few attemps)

Step 2: Second Method

the second method requires some sellotape

first get your sellotape and cut about a inch and a half off
then stick it to the centre not leaving and part uncovered (leave a bit of sellotape for your fingers) and yank it as hard as you can this also may take a few attemps

Step 3: Method 3

if by now your speaker is still stuck in then its very stubborn!

anyways what you will need for this step is a vaccum cleaner so this is reerly a last resort because you should have had it unpopped by the first step

what you do is(this one's obvious) find the right attachment to fit the bubble in the centre and set your vaccum to the highest suck it has, then turn it on and just place it over the bubble and just leave it until it comes out!

(this can also be done with a hairdryer)

Step 4: Finished!

now you should have a nice sounding speaker(again)

sorry about the images my camera wasnt useable or else i would have shown more in them

    My 7 year old got curious about how my new Mother's Day present TDK Sound Cube worked - I've only had it for two days! I didn't have any duct tape, and I couldn't get the suction method to seal... So I got creative and used bandaids. I went through a few because they lost their stickiness and it was a biggish dent... But it worked ;) you can still see the crush marks on the gold-coloured dome, but at least it isn't all pushed in any more. Thanks for the advice! Got it sitting on top of a much taller cupboard out of reach, now.

    BANDAIDS OMG. I tried tape and superglue and no result. I had no vacuum small enough either (computer speaker) so I saw your post and used a bandaid and BAM its out. Too bad I already bought the duck tape and super glue.

    Wonderful tape worked really well. Cheers

    vacuum worked immediately! didn't have duck tape so don't know if that will work. if u r wondering if u should take the time, ur answer is yes! my sub is twice as loud!

    Vacuum cleaner worked like a charm! Gracias!

    yeah this way pulled the centre off of my speaker...

    I have 8' 20/20 Events and I actually dropped one and smashed in the middle bubble of my bass speaker.

    To repair it, un-pop the middle speker bubble (dust cap), I simply used my vacuum cleaner, it took a a little time, it doesn't just pop right out. You have to move the vacuum hose along the inserted part, and you will see it coming back to shape as you continue the suctioning on the speaker bubble.

    Hope this helps guys!

    WIth the duct tape works great! with my fingers the glue of the duct tape, doesn't stick so much, so i grabbed a small screwdriver and i started to gently rub the tape until i saw the fibers. Then i yanked a little and, i tore a little of paper surface, but the dimple is out. Maybe i rubbed so much. I've unpopped a subwoofer and a little one

    I used the duct tape trick and it work perfectly. Thanks !!

    I have a tweeter that won't unpop out no matter what even with a big cyclone vacuum :(

    I have a Two 12" Diamond Audio HP12. I have a small dent in the center dust cap as you can see of the left.. Any suggestions or methonds that wont harm the sound or damge the sub? Thanks.


    I used the tape method with duct tape on a small 3.5inch cone. It worked on the first try with no damage. Thanks for the tips!


    I have 2 18" MJ-18s who some loser punched a nice fist sized dent in each dust cover. I've tried everything short of poking a hole in it to fix it. Vacuum, tape, i made out with the thing for 20 mins. Help me, im ocd about my drivers.

    The vacum methed would seem the most practical way, Using tape could tear it ! But i suggest not using it on high,Or you could do more damage.             I  do not understand poking a hole in it like yerboggieman said would   help !!!  What dumb idea !!!!!!!!!!!!!!!    

    Dented dust caps didn't seem to change the sound on mine.

    1. in case you were wondering the center 'bubble' of a speaker is called a dust cap and 2. for method one i dont really want to put my chops round a dusty four inch sub! Great instructable xD

    in my younger days I acquired a speaker box from a local garage sale, was a name brand speaker box (brand I am unsure of because I scraped off the sticker for personal reasons) so i was excited, bought, brought, and hooked it up and it didn't sound to great I felt air leaks so I dismantled it but before I even got inside I noticed that the cone for the sub was punched in, I cut around it/popped the adhesive about an inch in length, and then fixed the cone (paper), but then ran into the problem, what glue should I use? I set it aside and am now tackling the problem over this weekend, please help! (and the vacuum method hasn't failed at all, props)
