Yep, been reading up on that. My thread was more or less about people that have started using them over ceramic speakers. As far as replacing the speaker in the TM. I wouldn't use one of the usual suspects, why add weight when that is one of the appeals? I would go for one of the Neo speakers... I ended up putting a Creamback 65 in my DR this weekend and love it so it would be nice to see if the Neo Creamback would be about the same but without the weight.
