I have built the regular 2 PIs, which are the same just smaller. Check out my website: http://www.missouri.edu/~lnra54 You can find some pictures there and a mini review. Building these speakers is pretty easy, the only difficult part is making straight cuts (they need to be "perfectly" straight). You will need access to a good table saw and a router/jigsaw to make the baffle holes. These are very good speakers for the price. They cost me less than $200 for a pair including everything. Also, there's a gallery around but I don't know the address(you might want to do a search).
