After that we cleaned them and did a clearcoat on it to protect the finish which is baked under UVds  ( the lines on the sides were put back on later and are handapplied with a matt lacquer)

I am very pleased with the result and they look amazing .... glad you liked it

Very good indeed. I've polished various aluminum items, mostly wheels, to mirror finish and your project looks like something I'd like to replicate. I assume the case material is fairly soft and easy to polish? So far my worst experiences of polishing have been with a kitchen sink, that steel was damn hard and it took me 6+ hours with pro equipment to refinish it.

Too bad all my C- and CX-series speakers are in way too good shape. Maybe I'll have to find myself a pair of scratched ones on eBay just for a project like this... you're speakers look absolutely gorgeous. 😳

Hi Henri,

Yes, indeed basically same process as polishing wheels. It took us max an hour per speaker to final polish. Overnight for the protective coating.

The cx casings are aluminium so fairly easy and fast to polish. Kitchen sinks are stainless steel and you will indeed need something more efficient for that...

Glad you like them  🤒 .  

Wow!!!! Love the finish you've achieved

You could almost set up a business doing up CX's!! They look better than the originals!  I need to find myself an industrial belt sander...I must have half a dozen pairs in my cellar awaiting some TLC.

Cheers

Hi Nigel,

Send them over .....😁😁😁 ... I'll put up a  production line as I going to have my other pair refinished as well.😕

Glad you like them.

Though if I would have to sell them, I doubt to make back the cost. It's so much more economical and easier just to repsray them (with black as the most (re)sellable colour, I suppose) I just hate black speakers myself. 

I just did it as a test and because they were really badly scratched and I preferred to have a finish that matches the rest of my stereo, so for me it was worth the effort and money.

To complement my cx's I am looking for a cona right now ... actually just the shell. If anyone has a top shell of a cona (reasonable condition) and is prepared to send it to Canada please contact me, I am sure we can work something out. I bought one on ebay and it came with the top totally broken ... 

Those chrome finish polished CXs really do look excellent.  I guess with 3 months of darkness and winter one has to find something to do!  (Depends just how far north in Canada you are!)🤒

I had not thought about painiting the speakers - but perhaps should experiment.  Does anyone know what is under the black finish?

Hi Brian,

Glad you like the polished CX's. 🙂

Anyways, I am in Montreal so not that far up North anyways and only a couple of hours from NY.  I have been planning to do these for the last 2 months or so but just never found time for it.

Under the (anodized?) black finish is just plain metal. If you have previously painted ones, give them a quick sanding with wet sanding block 120 gritt than 600 grit would do it. Depending on the paint you're using you'll have to use a tinted primer (or not) and if the scratches are too deep you can use a filler primer (like for car body work) .  

I have painted plenty of speakers in all kinds of colours of the years. Ranging from simple black to racing green, metallic purple and even pearlescent pink..... (on request of a sclient as a gift for her 12 yr daughter...)

I no longer spray these myself as it always has been a hobby for me, (no time nor place anymore) but do sand and prep them myself and have them finished in the local car body shop were they can spray them in the colour of your choice including pearlescent and mettalic finish coatings. These finishes, though sometimes pricy do last a lot longer than any spraycan finish and look fantastic when done by pros.

Regards,

I am new to Beoworld and I am thinking of refoaming a pair of CX100s.  Your post is very helpful.  Can you tell me more about how to hook up a battery to the speaker?  Thank you.

Hi and welcome to Beoworld, If you take a 1.5 volt battery and connect it to the driver. It will either pull the cone in or oush it out, depending on the polarity. What I tend to do is once I have glued the new ring to the cone of the driver, and let it dry for 24 hours. Is connect it so that it pushes the cone out. This gives you more space for glueing the outer part of the ring. Then I connect the battery the other way round. This pulls the cone in and centres it too. Then I hold it in place with some close pegs. Once you have done this you can disconnect the battery and push the cone in a few times by hand to see if it scrapes. If not just leave it to dry. One repaired diver.

Trying to refoam my CX50's was a learning experience for me.

I learned  that I lack the skills and dexterity to refoam speakers! 🙁

I can however confirm that the original drivers are still available through  B&O dealers, and  that a quick call to King Street and a trip to Manchester solved the problem!

Last time I checked they were about £25.00 each.

They are still 25.00 each, and soldering the new ones in is lots easier than refoaming the old ones! 😎
