I hadn't seen this site when I built them, I just read the "Griffin paper" a couple of times, I bought a few cases of NSB's and went to town. I really need to work on the crossover, it's a 2nd order LR at 3.5k. I didn't weigh down the nsb's like people recommend, I didn't even put in all the screws, I'm still kind of playing with things. I don't like the single tweeter. Not as "in you face" as I've heard other lines. I put it half way between ear sitting and standing ear level. This was a bad idea, as they only sound good sitting or standing, and great if you hunch over a little. My next lines will have a full compliment of tweeters.
I actually like the center channel, my wife hates it. That tweeter doesn't quite keep up with the mids. You have to be in front of the center channel, but that doesn't really bother me seeing as it's as wide as the TV, and if I'm going to sit and watch a movie, that's where I'll be.
The sub is 4 12" Dayton DVC's, sealed .707, running off a QSC 1850 HD that I keep in the basement.
I like this site and I'll be here picking brains for as long as you let me.
