I have no clue about the 2.2s, other than reputation, but I owned and loved my 1.5s for 6 years. I lived with my Thiels for 5 years before I went with a sub. Since the Thiels have great lower extension, to begin with, I crossed them over very low. 45Hz. Highs are weak: a little hard, harsh, metalic, if you will. Vocals: ooo la la. These speakers won't do it, if you're a rocker, without a sub. Happy listening. peace, warren
