It's hard to know what to think of the new design. I looked up the manufacturer and they seem to be marketing to DIY'ers and boat owners, since the drivers are waterproof. There don't seem to be any independent reviews of the drivers on the DC Gold Audio site; until I read about them, I will stay on the sidelines.
I, too, own a pair of 6.9s, (and a marble 4.0 center) which I really am happy with--the only weakness being the very deep footprint. I am going to be up in Bangkok in February so I am going to try to get to the showroom and arrange for a listening test. If/when I do, I'll be sure to post my thoughts here.
