Thanks for the links, I think I've seen (parts of) both videos but now that I have learnt a lot more I think I'll pick up more info.
Btw there have been a few valid criticisms of these speakers, although it's more of a "they aren't really the best in the world" rather than "they're shit" type of critique. I think ASR forums or diyaudio.com might have a few thread(s) on it.
