Hi all I have been up in the loft and dug these speakers out that have been up there a number of years. I picked them up at a car boot sale about 10 years ago. When I got them home they didn't work properly, so I put them to one side and forgot all about them. I am setting up my new system I wanted something to use as my surrounds and I knew that I had some bits up in the loft. I found a set of W/dale Diamond III's, A pair of MS festival series 2's and these. I am now interested in getting them going as I think that they might have some quality to them. They are very heavy. I thought that they were made of slate or similar, but looking at the chip on the corner (see photo) I think that they might be concrete mouldings. The comany name on them is 'Shan Acoustics' of Unit A2.08 Portview trade centre. Model 'Shimna'. A quick check on the internet turned up nothing except that there is a 'Portview trade centre' which gets a lot of hits for Belfast in Ireland ??? My question is how can I tell which bits are still OK.. I am not into DIY electronics but I'm willing to have a go with a bit of direction. I do own a soldering iron, but it is only an RS (Radio spares) butane type with multiple fine tips. Would this be OK? I have taken pictures of the drivers and the insides of the speakers. Please give me some tips on how to proceed. Is it possible to get exact replacement drivers etc? Thanks a lot in advance for any help that anyone might be able to offer me.
