TRADERXFAN,
Those parts won't swap over.
For one the X-Static uses larger 6.5" woofers, and then a soft dome tweeter. The woofers are similar to the M-130's used on the OB-5 and OB-7 just larger. The tweeter is no planar magnetic but it is easily one of the better sounding soft dome tweeters that I have worked with regardless of price.
That speaker (the X-Static) will raise the bar for any speaker under $1,000. a pair. That is an incredible speaker. I guarantee you it will win a ton of awards and it won't surprise me at all to see it on the cover of a major magazine before the end of 2008.
The parts quality is really good from the factory and even includes some Sonicap Gen.2 by-pass caps, but the network can be taken up a notch, and you could line the cabinets with No Rez... No doubt that the Skiing Ninja will offer a few upgrades to take them over the top.
Even after upgrades, I'd personally still favor the OB series because of the planar magnetic tweeter that they use, but you could easily go with the X-Static and not be disappointed at all.
