What I have found with the 3.5s very recently is that positioning is actually more critical than advertised to get the best bass response.
Of course this is probably very room specific but I've now discovered that sitting just inside the triangle with them as wide apart as my modest music room width allows, with a decent amount of toe in, makes a staggering difference. Previously I had tried positions quite a distance from the Thiels, thereoretically to give them more breathing room. I've found out that, in my situation at least, they don't need it. The 3.5s have effectively disappeared aurally speaking.
As Dave observes above, the bass response is actually extremely tweakable with Thiels.
Although i I didn't think I needed a sub before, I think that is even more the case in light of recent speaker juggling.
