Thiel Owners

The Thiel CS 6's are less sensitive, the minimum impedance nearly half that of the Theil 3.5's, and the Thiel recommended more power for the CS 6's (100-400 Watts per channel) than the CS 3.5's (50-250 Watts per channel).

UNSOUND - I have always been curious about these power ratings. Are they taking into account impedance at the higher rating? For instance with the CS 6 is the higher rating due to lower impedance swing?

I've always assumed the recommended power was based on an 8 ohm load since that's how amps are normally advertised. It was up to you and your dealer to recognize that you needed one that doubled down at 4 and 2 ohm. 

robinbarbour, While that would seem to make sense, I can't confirm or deny that to be true. Please keep in mind that while up until very recently one could find many attributes that Thiel speakers shared, Jim Thiel got there through various means. With the speakers under consideration, the 3.5's and 6's used eq'd sealed boxes or passive radiators, different box volumes, and perhaps most importantly different drivers and at different price points.

saffron_boots, Yes, Jim Thiel told me that his power recommendations were based upon quality 8 Ohm ss amplification ratings that could double down, and if one were to choose to use tube amplification they should double the power accordingly.
