I wanted the 80's, I have never heard the 80's, but now know that I don't need the 80's. Although It would be nice to have a pair of High Gloss Orange Piano FInish 80's. My needs are probably different from yours. I don't need to shake my house of the foundation and I don't think I will ever have a center channel. The 60's are more than loud enough and low enough for me.
Good luck!
