A very familiar story where people replace these drivers with so called "better" units only to be disappointed with the results. One of our members (jOhnbarker) replaced the bass drivers in his MC120.2's with some Peerless 830667 units of very similar specifications with good results by all accounts. It may well be worth taking a look at the thread and deciding if you think this would be worth doing, personally I would give it a go as these are wonderful speakers and it is very doubtful that you would find any original drivers so this could be a very good 2nd best.

I bought the speakers like this, have't done anything to them. I just noticed they are woooowing tad more than necessary. And looking at some photos here I noticed the visual difference.

Thanks, will look into definetly. I will have to se where to get also the fire retardant acoustic foam to replace it with that scrap I found inside.

The foam looks original to me AFAIK.

Chris.

I have seen the speakers from Mr. Andy, on the pictures from the thread he linked few posts up. Here is the photo:

And the foam (actually sponge) has a heat burn from the coil on the circuit board, that is why I have a doubt.

Overall the speakers are not that bad, but the bass is really annoying me sometimes. I don't have an B&O impression if you get what I mean. Especially when I saw the woofers I am having inside it got somewhat clear to me why they do not sound so uniform.

Totally different foam to mine Chris!  This looks like sometyhing you can buy down the market for making your own cushions. Mine was more...er...fluffy.

You could both well be right, I've lost count of the different speakers of this era I've worked on over the years and all sorts of different damping materials have been used in them. Short of taking my MC120.s off the wall taking them apart I'll bow to your knowledge. 😐

Chris.

Just to add my two penneth to this discussion:

The foam in your MC120.2s looks exactly the same as the foam I found inside my speakers when I opened them up. The shapes, colour and texture look exactly the same. I wonder if B&O changed the specs at some point in the production run though, as Andy seems to have something a bit different in his.

Those Peerless woofers that I bought are excellent. After a few weeks of light use they were eventually well 'played in', and I can thoroughly recommend them to you! The bass is a bit more up front than with the original woofers, but my old ones were knackered so it's hard to say what they would have sounded like had I bothered to refoam the originals instead.

I could agree with Mr. Andy as from what I have seen from his photos and on the internet while googling that "fluffy", fiber stuffing is the correct one for these speakers. It doesn't take as much of volume as the sponge, atleast, as it is not as dense.

Also, as mentioned, the sponge is burned form the coil on the back of the mid-high enclosure. I doubt B&O would put something inside that is melting with the temperature increase. Most, if not all of this stuffings on the market are fire retardant.

That is just my opinion. Anyway, I doubt that distortion of the bass is coming from the sponge, it is just the cheap driver that is installed.

Thanks for your opinions guys!

Does enyone have a pair of those original drivers? Or knows someone who has them.

Hi there,

Perhaps B&O changed the foam at the .2 update. My S80.2 have exactly the same yellow foam that yours has in them too, and I have seen other photos with the same foam (John's included) so i suspect it might be standard.

For drivers perhaps Martin (member Dillion) may be able to assist you.

That's interesting, thanks for your info.

I ahve already contacted him (Dillon) but he doesn't have a pair.

Anyhow, if anyone comes across of a pair of those drivers, please contact me.

Thanks!
