After briefly flirting with the idea of selling these, I've more or less decided to rebuild them. First of all I'll rebuild the L/R and maybe the centre (but I'm not sure on that yet). I'll probably rebuild the Volt 8's also or may replace them with Volt 6's as I think the 8's are just too big.
This is what the L/C/R look like now except some of the mid's and woofers are damaged from the kids. In hindsight, it wasn't a good idea putting speakers like these in the sitting room with a 2 and 3 year old as they acted like a magnet for little fingers, chalk, pens and markers.
I'm in discussions with Erich on getting replacement speaker units and hopefully some baffles. If I can't get the baffles I may need to have them cloned if possible. The main reason I want new baffles is that I cut a corner of the tops and bottoms of the original and now I want them square to fit speaker grills. I've also slightly rounded the vertical edges. Perhaps I could repair them but they may never be right.
I'll rebuild as the original stand mounts rather than floor standers.
As for materials, I've found a wood working company that will essentially supply a flat pack. I send them the cut list and they'll cut all the pieces of wood I need. It's expensive but the cuts will be better than I can do myself. I'm going with Baltic Birch 36mm (2 x 18mm glued together) for all walls/sides and 18mm braces. Perhaps a 25mm dowel bracing the top and bottom.
I'm considering not staining, dying or painting the cabinets and leaving the natural plywood look. I will treat it somehow with oil or varnish/lacquer. The baffle will be painted if MDF but if I have to clone in Baltic Birch it may remain matural.
I believe the the original design cabinet was around 28" (711mm) x 10.25" (260mm) x 12" (305mm) which gave a volume of 40L. To achieve the same volume I'll need to build a 400mm depth so I'll build to 40L to 45L (about 450mm).
Those are my thoughts for now. Everything subject to change
