Thanks everyone, for the encouragement!
I just had a call with GRR, and it looks like the high-end NX line is really for two-channel audio and not well suited for a home theaters, especially with the open baffles, 3-foot from walls requirement, etc. (not great for little ones who may be crawling around them!).
So, I'm now leaning toward his recommendation of smaller (and cheaper), fully enclosed models that make more sense for multi-channel listening.
I love the value proposition of DIY for getting big sound without big money, and I wish GRR had a page that was dedicated to home theater applications, like mine. Right now I'm looking at two front speakers, one center, four rears, and up to four subs in the corner of the theater, two with 12" woofers and two with 15" (we really want the bass!).
Any other recommended reading, for applications like this? I'm guessing there's forum circles dedicated to this stuff that I can find... the amount of info here is certainly intimidating for a noob...
