I agree with Jfrech, the 104/2 is one of the best speakers that I have had. No, not a perfect speaker, but it can be extremely musical and has a presentation that is better than speakers costing tons more. Talk with KEF, they are ( or once was) good to deal with. Or, you could take two aspirin and bolt an Altec horn on top of it ;-)
There's a YouTube video on the replacement process, which takes some work. There's an eBay refurb service for the originals. The originals are no longer available.
I couldn't find any replacement drivers for my 104/2's. Called Kef and they didn't have them anymore. Loved the speakers for the 27 years that they still worked. I guess they don't owe me anything after that time. My son still has them as conversation pieces. One of my bass drivers doesn't work either. Cost quite a bit more to purchase newer speakers to replace them.
