I suspect the cheap drivers to be unsuitable for the job and therefore sound weak, but I expect somewhat difference in volume compared to the original ones.

To me, nothing seems to be damaged on the crossovers. Overload protector is pressed in, can't see any oxide on it. 

One thing I could mention is that I'm not testing this with a B&O amp, I do do only have some old nad-amps and maybe the bass would be better with suitable B&O equipment?  

As you can see, the foaming is completely damaged, so I'm not expecting any good bass out of them before re-foamed. 

First step: Fix original woofers! Where do i buy the re-foaming set?

Thanks in advance

Welcome to Beoworld Oyvind🙂
Your 120s look lovely in white, thanks for the photo's.
I refoamed mine recently, and am extremely pleased with the result, and use them daily.
Good Hifi has a good name, so I would agree with getting foams from him.
HERE is a photo'thread I made showing my first attempt at refoaming my 120s.

My Beovox S120 are also white. This is very rare so keep them original and in as good condition as you can.

Foam rot yes so Dillen did the service and they sound wonderfull.

Its a complex job if you have no experience doing it before.

If you send them to Dillen they will be perfect when you recive them.

Thanks for all feedback!

Unbelievable, cabinets are still like new.

Jandyt, your thread was exciting to read! I'm considering doing this job myself, mostly because I'm on low budget, but also because it had been fun to re-foam a set of speakers myself. Only question is where to get a set of new dust-caps, if I bother changing them. Do i need any special shims made for these woofers to center them, or could i use something from my own garage?

Eventually, who is Dillen and how do I get in touch with him?

I acquired a pair of MC120.2s with both woofers rotten, and one of the voice coils fried. I wasn't willing to look for a spare unit and then go to the hassle of refoaming, so I went and found some new Peerless woofers that matched the specs of the originals. You might find this thread interesting. I can certainly vouch for the replacement units - a straight swap and very good build quality.

Dillen is a user and moderator on this forum. He lives in Denmark  and is an invaluable source of advice, service and spare parts for vintage B&O.

You can contact him by sending him a personal message on this site.

The thought has crossed my mind, but I'm keen on fixing the original ones since the voice coil seems to be ok on both.

Peerless drivers are also a bit expensive, those cost around 100 euro here i norway (for one). I'm on a low budget and if I'm ending up spending a bit of money on these speakers, I think I will be re-foaming the originals with help from a pro.

Yep - my new Peerless units were £50 each, so that sounds about right at 100 Euros.

The speakers were given to me for free, so I saw it as a good investment, as two new rings plus glue was approx £20 anyway...

I understand your choice of solution, especially because the burned voice-coil. Your result do look (and probably sound) very delicate.

I also consider to do this job myself, in an amature way, just ordering what i need from the Netherlands. I had to pay 800nkr for mine, roughly around 100 euro.
