I came across this website from the Audio Circle forum and needless to say the designs are very interesting. They are mostly all done with full range speakers (Fostex mostly) but he has a couple of 2-ways in there as well. Cool thing is that he also has measurements of all the different versions he makes as well. Most of the designs are very cheap to make since one will spend more on cabinet than drivers. The way the angular cabinets are made they look extremely inert and he uses double front baffles and rear walls. Anyways check em out as they would make a cheap DIY project with most likely very good results. http://www3.ocn.ne.jp/~hanbei/eng-intro.html
