 The sound like a dream..

Sorry for my ignorance, but I have a pair of Beovox C75 that I would like to restore... when you said "new speakers", where did you get them? are they B&O replacements? other brand?

Thanks!

It's just okay, you can go to you local Bang & Olufsen Shop and ask for the speakers.. If you dont got a local dealer.. Maybe call a Danish company to get the new speakers, and then send them.Can't see where you from..

Drivers for C75's are no longer available but I know of someone who simply used the CX50/100 units and the results were very good. You could always refoam your existing ones to keep them original. I wouldn't consider using different manufacturers drivers as historically they don't match up with most Beovox speakers.

I am aware of the problem with the c75, about the drivers... I would replace with cx50/100 drivers, no one can here or see the different. And then your speakers are upgraded to cx50/100..

Jankay , The CX100 drivers do not fit straight into the c75s the holes are out of alignment. I tried to do this  but what i ended up having the C75s speakers re-foamed, and they work brilliantly after some hours bedding in.

How much do the CX100 drivers go for?

I was quoted AUD$66 / USD$60 a couple of weeks ago for new CX100 drivers from B&O

Thanks a lot for all your quick responses. Well, I am based in Buenos Aires, Argentina and there's a B&O store represented by a distributor in town. I will ask if they also import spare parts, but I'm not sure. Otherwise I should order from Europe or USA.

The drivers were already refoamed when I bought the speakers, and honestly was not a nice work what they did. That's why I'm considering a deep restore... although I can't assure this is affecting the sound quality. I still could't test them deeply.

I assume a capacitor replacement on the crossovers would be a complement.

Anyway, there will be still the holes alignment difference to resolve... I guess it can be solved.
