"I might also add that the 3.7i is a superior speaker in every way. "
I did not care for the sound of the 3.7i in my room. The 2.7 uses a shorter ribbon that crosses over at a lower frequency than the full size ribbon in the 3.7i. More true ribbon is a good thing to me. the larger panel in the 3.7 will give more bass, but I would be using subwoofers with either speaker. It is the same height at the 3.7 which is the big difference from the 1.7i.
