I've owned the 1.6's and 1.7's and eventually, 3.7's. Of the 1. series, they are both excellent, but I preferred the 1.6's....maybe it was a case of absence makes the heart grow fonder...I don't know. I paired them both with a little Sunfire sub. Incredible. I had my 3.7's paired with a Rel sub.
But if you are looking for a warmer sound, look elsewhere. They also both require quite a bit of power to make them sing.
