Do Thiel Audio CS3.7 Rock?

A local buddy of mine has a pair and he listens to mainly dynamic types of music. The 3.7's are not like most other Thiels having a LOT of topend energy or bright. I was quite impressed with them. THey do like power as most Thiels but are not terribly inefficient.

Said before, but worth repeating.
Jim Thiel told me, back in 1988, during the development of the CS5, that a technique that he and his brother Tom Thiel had realized, was that by dropping the impedence of the bass driver(s)...the amp would be compelled to deliver more current...acting (paraphrasing here) as an equalizer in that region. At that point, he was appalled at the lack of current that most amps, even those claiming to do so, could deliver.
The 3.7 is rated at 90db efficient...which IS effecient. What gets lost in the transfer of info here, is that the THIEL speakers like, and generally require, amps that, because of this design parameter, can deliver current.
I agree with the poster who said, look at the Wilsons for rock and roll...I've never considered the THIEL's that kind of speaker. (rock). Accurate, great imaging, detail etc...not great punch though.

Good listening,
Larry

While Thiel's might not be the last word in "punch" or anything else for that matter, I've never really thought of them lacking in that department, or any other for that matter. I think the appeal of Thiel, is the overall balance of all parameters. There are certainly some speakers that might do somewhat better in a specific area, but usually at the cost of doing things much worse in other areas.

Ayre and Thiels are a good combination. Thiels seem bright to those that use inferior equipment. Actually they are very good speakers and not bright at all. ..just looking at the suggestions above....sure you should listen to all, but certainly Thiels are better than B&W 802's which are dead and flat in comparison. (just one person's opinion)

I agree with Stringreen that the Thiels need great partnering equipment to sound it's best.

A buddy of mine paired the 3.7s with either a Hovland HP200 or a Leben pre (both tubed), and a Pass Labs X350.5 - totally not bright at all. In fact, it's very natural n quite neutral

It will rock pretty good unless you compare with speakers whose features are simply to rock
