One of the woofers in mine stuck and I had it repaired. Well worth it. Better to get the drivers repaired than replace with new drivers unless you can get originals.

I also had the capacitors in the cross over replaced, though Tim Jarman did that.

Thanks Peter! I read your previous posts about the m100 stuck (slipped?) magnet. What does it mean? How do I identify if my magnet is at fault?

Thx

If you press on the woofer ,normally you can move the diaphragm in and out. If the magnet slips, you cannot. However there are other reasons - I am no genius at fixing electronics, hence my use of professionals. Some of here can advise how to do things yourself.

Hmm, I will investigate further!

Ok, I might have found someone stateside that will recone these. Another thing to check out I guess!

Does anyone have any info on the midrange  filler driver? The one that is enclosed inside the speaker.

Part numbers, maker, picture of the back, specs, anything? I found a few 4.5" drivers but have no idea what to aim for...

Thanks again!

Stateside I can recommend this place -

I think I would like them too, and I am all about fixing things rather than just chucking them, but that doesn't resolve my issue of missing midrange drivers. The information online is scant at best!

Someone out there must have taken them out at some point, and knows what they are!
