The GR Research people sell a well designed kit (link provided in my previous post) and include plans for the cabinet. You could email or call about open back design and see what his experience is.
As for shopping, I thought the price was great. $1995.00 for 16 BG ribbon assemblies and 18 woofers, plus all the crossover parts. You might do better but this way the design is worked out and leaves the creative cabinet, finish and other fun stuff to you.
I even considered this for myself I though it was such a good deal. I really don't need them since I already own Soundlab U-1's but the fun factor attracts me.
As for performance, I have not heard the kit but the Epiphany speakers showed great promise, even under show conditions.
