Bowers and Wilkins 683 tweeter dent repair

A quick demonstration on how to disassemble the tweeter housing to push out dents in the tweeter diaphragm

[@emmettsullivan690]

I fixed mine with a handheld vacuum pump and an infant nose cleaner. I cut a section out if the ball area until it fit over the dent like a suction cup and connected the pointed end to the tubing on the pump, applied a small amount of suction and the dome came right back.

[@MrMikeej619]

Great Video. I just fixed my 684. You just saved me $$. Thank You!!!

[@emrelsd]

Has anyone else tried this method with a pair of 686? The tweeters are not the same but smilar looking ones both models were produced same year..Thank you for the video!!

[@_rowjack_4761]

Hi @emrelsd. I actually had a pair of 686’s as presence speakers a long time ago. I would hazard a guess that they’d come apart in much the same way. I believe the tweeter is the same, but the aluminium badge and the plastic behind it is just slightly shorter in length.

[@irelmo69]

I feel your pain! I had my 2 fronts and the centre done in one go and 2 weeks later the centre was pushed in again! My kids are now a bit more grown up so now I'm going to repair if possible but replace again if not.

[@TheSpoolin77]

I got a set of 800 Nautilus from a guy and one of the tweeters on the sc1 was dented. Ordered a new one from B&W parts and started to take on the repair. Once apart I basically did what you did but I found using a phone or tablet rubber tipped stylus worked magic. Give that a try for the people wanting to attempt this delicAte form of paintless dent removal. 😁

[@mattiasclaesson8885]

Great video, thank you. Tried it on my CM7, a bit different tweeter but the same method worked, thanks!

[@garypranzo9334]

In a cool environment (Under 74F) 1. Blow dryer 2. Clear packing tape. 3. Heat the tape not the tweeter 4. Place over dent trying to make contact inside crater 5. Go do something else for an hour or so 6. Put a finger gently on a non damaged part to hold dome so you do not pull dome out 7. Lift carefully straight up but this is where what you do next will vary (Sometimes angling it a bit will help here and sometimes not) At best and If you are lucky the dent will come up perfectly but it will leave a faint discoloration where the dent was. At worst you will get the dent out but it will bumpy in the dent area. I add this because not every BW tweeter dome can be accessed this way. The bottom line is BW took way to long to address this and add tweeter grills.

exactly what I was needing

[@KingKongMartBob]

Vacuum didn't work for me. This is an easy repair with that video. Thanks.

[@DrEmstri]

Hi excellent video! I know this is an old video so crossing my fingers for an answer. How is the diaphragm itself attached to the plastic frame? Glue? What kind of glue is apropriate for this? And how do I safely remove it? Many thanx 🙏

[@_rowjack_4761]

Hi. It was glued to the diaphragm. I had an old tweeter completely apart a year ago (although didn’t video it). I googled the same question at the time and deduced it was either cyanoacrylate or epoxy. I assumed that being B&W they’d use cyanoacrylate and so I used nail polish remover. That loosened it substantially and I was able to fully and cleanly remove the rest with a craft knife. I didn’t put it back together, but if I had, I would use cyanoacrylate. Only because I absolutely hate using epoxy 😂 Hope this is helpful.

[@DrEmstri]

Thank you for replying 🙏 I got a pair of 684 S1 yesterday with one damaged diaphragm. Figured I will try and replace it myself as soon as I can source one of decent quality. 😊 Job seems a bit fiddly but pretty straight forward. Maybe I'll even record it.

[@jonpatrick66]

Good job! Thanks for the instruction!

[@moribass5160]

Would be great to see a vid of replacing just the dome! As you cam get spares of these

I'm sure I have an old one kicking around somewhere. I'll see if I can dig it out in the garage tomorrow and will link a video if I still have it.

I'm intrigued. What does that do for it?

[@johnsweda2999]

@@_rowjack_4761 well comes down residence in the diaphragm stop back reflections as well. Should make the tweeter sound sweeter and have better time delay

[@Tangyorangutan]

Hey Frankie thanks for this video! I have a 686 and it looks like that little plastic cone on the back of the tweeter is broken off. Should I re-attach it or is it unnecessary?

[@_rowjack_4761]

I would definitely reattach it. I can't say for sure but it looks as though its there to dampen vibrations and probably helps prevent the tweeter sounding tinny.

[@Tangyorangutan]

@@_rowjack_4761 Thanks a lot!

[@spacescraper2009]

@@Tangyorangutan @Frankie Howard would you use glue or a high adhese double sided tape please to attach the plastic cone? ive had this happen also and wondering what to use and how attached it needs to be :) thank you

[@Tangyorangutan]

@@spacescraper2009 I used glue! I can't remember exactly what type (epoxy/wood glue, perhaps JB Weld) but I applied the glue, re-attached the cone, and placed it upright on a soft towel (or any soft surface to protect the tweeter) and let it dry overnight.

[@LLS1978]

Thanks a lot for this! 👍 My buddy has the same tweeters in his speakers I think. But his tweeters has holes in the diaphrams. Does anybody know if these can be replaced or we will have to get all new tweeters?

[@brodiehaward]

If you call b&w I believe you can order just the dome/diaphragm. I am not sure if they send it assembled with the plastic plate and the terminals, or with just the dome coil and bare leads. I believe you get the dome and have to attach it to your original plastic plate with terminal connections. I have found b&w very helpful and willing to sell you parts no questions asked.

[@vietenthuse]

I just purchased a new tweeter. It was relatively cheap.

Are tweeters exactly the same for 683 684 685 ? They look very similar

The tweeter is the same but the silver oval name plate part is a different size for each

Can you please tell me How many ohms are they

[@_rowjack_4761]

I’m sorry, but I don’t know that.

it’s ok . Thank you

[@danielcave9606]

How did you get the other speakers out first? From the front or back. I can't see any access points.

[@jamescollins6085]

You need to pop off the plastic facade from the midrange driver, behind you will find 8 screws. He goes over this in the video here: 00:35

[@danielcave9606]

Cheers James, A bit more assurance on how to do that would be super handy. I REALLY dont want to damage my super nice speakers. I did try sticking in a very small screw driver to pull the housing forward but i didn't have the cahones to give it a heavy handed attack.

[@jamesehoey]

I had the same worries but then just gave it a go and it popped out fairly easily

[@jamesehoey]

Daniel Cave go for it... it’ll be fine...

Tried with the Dyson. Didn't work. It would have left horrible creases in the metal if it did, too.

It’s not a replacement, he repaired the dent before making the video

[@joefriday1320]

My B&W 683 tweeter replacement part came without the plastic housing part with foam material on the back of the tweeter. At the base of the plastic housing are threads for the plastic ring to secure the tweeter in the speaker box. So, I need to remove this housing part from my old one with the broken tweeter dome and reattach it to my new tweeter replacement part. What do I need to do to remove this part without breaking it and attach it to my new one? Is this housing part held in place using some sort of a super glue? Any ideas?

[@_rowjack_4761]

Joe Friday Did you buy direct from B&W? If you did you should send it back and ask for a full replacement. If not, I have an old tweeter here. Give me an hour to run an errand and i'll get it out and take a look for you.

[@valsoundsystem8805]

É domo titânio amigo ?

[@bigstick5278]

A dented dome would have been a good example. You will still have small bends in the metal wont completely be smooth.

[@_rowjack_4761]

Oh, for sure. But it'll be a heck of a lot prettier to look at. Unless you're a computer, you won't notice any difference in sound quality either. I only thought to record this video for people after I'd smoothed out the dent and realised how much of a pain in the neck it is to do.

[@vredewold]

Use the vacuumcleaner, to get the dent to pop out.But be careful. do not disassemble

[@_rowjack_4761]

Didn't work with a Dyson.

[@garypranzo9334]

Will work if you are lucky or you might suck the dome out of the speaker. These are not like other tweeter domes and do not respond to suction in the same way.

[@daftmoonz9395]

Just don't dent the tweeter of the 800 D it's dome is made of diamond.
