I guess on side note I have come across some speakers that parts express sells from japan and they are really cheap. Looks like they up charge quite a bit per speaker to unsuspecting people. That's the reason I don't like them. Can get same speakers they sell a lot cheaper somewhere else. I guess what they do do is sell kits to help people build decent sounding speakers but I would rather learn myself and think outside the box on what's possible. That's how things are invented.
