In many cases the the surround or spider has sagged causing misalignment and rub. As well as the fix shown here (a good fix BTW) you might find that mounting the speaker in another orientation will equal-out the sag or distortion. Commonly with front mounted speakers like shown here, you can rotate them 180 degrees and the coil alignment will improve; reducing or eliminating rubbing.

You absolute legend!!! Monitor audio gold 10 speakers worth a lot of money, one was crackling, I watched this video, realised it was rubbing in the middle like yours, a little fidget straitened the center of the cone boom 💥 worked like a dream. Thank you so much !!!

Those speakers look well built

Just tried it on a 1950s alnico 12” speaker. It worked. This guy is a genius. Thanks, SIR!!!!!!

Clever fix. I have a Pioneer 12" for my car and it started making a lot of noise. I've heard that it can be from subs sitting facing outward like most home speakers are. Ideally, they face up or down in vehicles and in home theater situations (down-firing being the best in most cases) but that's not always possible with most home setups. The heavy use combined with an outward-facing stance can cause the coil rub. You'll know it's coil rub if you can increase the volume output on your sub and the noise doesn't get proportionately louder (it may get a bit louder from more vibration but it's not nearly as audible at high volume as it was at low volume). One way I semi-fixed my coil rub (for the time being) is by standing it upright and letting it play. The coil rub went away for the most part after about 30 seconds of playing music through it. I've seen people use rubber bands to wrap around the coil behind the speaker and create moderate tension by wrapping it around and anchoring it. When you lightly pull it in the correct direction it removes the contact between the speaker and the coil(s) and you get the same effect. However, I'd recommend the way TeDubbs goes about it because that's closer to a permanent fix.

Thank you for making this! Mine didn't have screws and I needed to pry and wedge it back into place. This video helped conceptualize the problem and solution for me.

THANK YOU, my issue was slightly different (but also a dropped speaker) since my speaker is smaller and no allen bolts to loosen ( it has glue instead) but when you mentioned the magnet, and loosening it, I noticed it wasnt looking straight, with a little bit of bending it seems to have completely stopped rubbing and works great.

If the back plate is glued you can heat the plate up with a hair drier and GENTLY tap the plate into position so don’t rub. Worked for me.

Thanks for your video, I just fixed my F121 Funktion One Driver, after it was dropped side way and the coil rubbed ..I saw your video after I have already order a re-c0ne kit but guess it can sit in the drawer as a spare now that my F121 is firing away again. Great video .thx

Thank you! Someone gave me some Boston Acoustic tower speakers and one 7" woofer was doing exactly this. Looked and saw the magnet was bent off center. A little leverage with a screwdriver on the housing and -- boom! -- good as new! Thanks, mate!

About to try this on the speaker for my bass amp. I'll let you know if it worked

Fixed a peerless p835037 10" out of a Neumann kh810 sub this way. It must have been dropped during shipping and the basket moved

Top job. Thanks heaps. Cheers from Australia 🙂 👍👍👍

thank you mate you have saved me a fortune

Thanks for the info.

do you know if this works with coaxial speakers?

Dude you're fucking awesome. This is exactly the issue I'm having and it was gonna cost me 250$ for a re-cone. Gonna try this immediately. Thanks... Wish me luck!

subbed...idk if this question is related or not but would a coil rub show a different impedance than normal?

Ugh... idk if my first comment went through... Hopefully this will work on extremely old speakers too. I’ve got an old zenith radio tabletop that I patched but still sounds blown. The speaker is already fragile enough since it’s old paper...

my magnet doesent have any screws i think it's glued

My speaker that rubs sounds more clear than the one that’s smooth any idea on why that is?

Hell to the yeah

Thank you this video helped

Good video.

What do I do with these Denon’s that have a goddamn frame around the voice coil?

I'm working on a 5 inch driver with coil rub. The permanent magnet doesn't have any bolts. Hmmm

😢 I don't understand English can someone write me the procedure? I too dropped my speaker... Thx!

Could this happen to a car sub? mine sounds very similar to that one and is quite annoying to hear. would it be better to buy a new one as I only paid like $30 for the entire woofer.

also, what the hell is up with these negative comments lol

You sound smart but please stop saying basically
