I built a pair of the Proac 2.5 clones many years ago for a friend (myself as well) and one of his woofers died. I went onto the Madisound website and find that the original was replaced with a newer version, but that newer version is also unavailable.
Is there something that I could use to replace these? The Fs is 25hz, so they went really low.
It is a 7" cutout. I don't remember what the crossover frequency was, nor how it was implemented. Troels Gravesen helped me at the time getting it tweaked.

Have you tried Audiohobby.eu ?? They carry it. I'd also suggest asking Solen.CA but the website is down at the moment.
The new 8535-01 is a standard driver in Scan speaks product line so I would try with a another supplier
8535 is a quite a special driver with a character and I have never seen one that comes very close

No doubt about that, I have them in my main speakers, paired with the 9500 tweeter. I watched GOT last night with these on, and I stopped using a subwoofer after I built these.
I saw the newer version available in EU, but not in the US anywhere. Madisound is the usual source here.

Hi Zacster,
can you be more specific on what kind of a failure it was? I had a Scan Speak classic midrange unit failed in a way that I thought should not have happened at all, considering how expensive it was like new.

This wasn't my speaker, I just built it for a friend about 10-15 years ago. He beat the crap out of it. The dust cap is missing, the tweeter surround body looks like a cat used it as a scratching post. I think he just had a cheap old receiver powering it too and may have pushed it too hard.
But ultimately it just doesn't react to any kind of power applied to the terminals. I was thinking I should check DC resistance to see if there is any or it is just open but that means taking it out again.

I have measured the same with the midrange units. Turned out a broken tinsel lead (both drivers) which I managed to repair, with some dificulties. Still a better diagnose than shorted voice coil.
I poked around to see if there was something obvious, but everything that I could see checked out. It is in the voice coil somewhere.
No, you can't see anything like that. Gotta start scraping off enamel on the voice coil part (not the flexible braid) to ensure there is dcr, if. In my case broken connection was somewhere underneath the adhesive where tinsel was attached to cone.
And a bit of irony to add: I put on my 50th Anniversary Beatles White Album and I heard a buzzing coming from one on MY woofers of the same type. I took it out, had a hard time doing that because I did a good job of making it a tight fit, pushed it in and out a few times, shrugged and put it back in. No more buzz. I also swapped sides on my amp because it will also buzz when the tubes start to die.
I'll keep an ear on it and maybe resist the urge to turn it up to 11.
