Actually, I do like the way they are, since they intergrate well. So I would certainly not do any crossover mods. As far as another driver, hmm, maybe when warranty is up. But I doubt it, they do have tremendous mid range. And I do have the lows covered with a sub, actually second sub is on its way
Remember this info is only for the mains, the other components are built differently, and for a center and surrounds, they lack no improper bass. What I mean by that is no they are not going to go to 35hz, but they surely are hitting 65-70hz.. Which is easily fine for those. The mains rated at I think 35, are probably much closer to 65hz and thats why it intergrates well with sub. And yes, they have been tried in 2 channel set to large as well. The Fluance set had much more bass, but did not intergrate with sub as well. They were rated at 35hz, and were probably closer to hitting 45-50 with some decent authority.
