I disagree with Stanwal,
I have heard the 3.7's many times and they have never been what I would call bright by any means, they are very natural and a little polite to my ears. They can have excellent bass, but they require huge amps to get it (best I've heard so far was with the big Jeff Rowland mono's.
That said, though the bass was tight and went deep, not sure they would rock. A speaker needs to have high output and bass to really rock, I loved my Escalante Fremonts and now my Wilson Sasha's as they both are efficient and have high outputs, especially when paired with lots of power. Not sure how well the Thierls would do in this area.
