I didn't need to build anything either but I got the itch and just built the c-notes. They have a 5in driver, but it's really closer to 4 3/4in. Now with that said, they sound really good but have no bass compared to my jbl arena 130s with a 7in woofer. However, their mids and highs are so much better, once I have my subs done then the jbl are going back to the kids gaming area.
I have seen others compare the c-note and the s2000 mt, saying it has a little better drivers and are a little more efficient than the c-note. So if you are going to built 3 MTM's then those should blow the Polks away. If you are going to do LR mt and then mtm center, they should still sound better.
I know a few people here have built them so try the "search this thread" and see what you can find.
