Thiel Owners

Thoft. Yes they are harder to drive I went from the 3.6s (25 yrs) to the cs7s. I don’t regret it but I need to upgrade my Bryston 4B amp now. They are in another league from the 3.6s IMO

Actually, as you can see from the above measurements, they are a very similar load to amplifiers. The 7's are a much better speaker. One of Jim's best. That's a great price for a speaker of this quality! The 4 driver 7's ease at playing deeper bass with greater dynamic range will probably have users pushing their amps harder to appreciate that over the 3 driver 3.6's which will will begin to demonstrate strain much earlier on.
Both of these speakers bass output is most likely to overwhelm a 10' X 13' room. A room of those dimensions will probably be better served by a 1 series Thiel.  

Suppose it’s a better idea to wait then isn’t it...

Unsound
well said!  I feel like my amp just doesn’t have the muscle anymore where I felt it drove the 3.6s. I agree the cs7 is an incredible speaker. Thoft read back to some of Tom Thiel’s impressions. He heard them a/b comparison to the 7.2s at coherent source.  I can tell you this they will clearly show you what you have in the front end of your system. Unsound brings up a good point about room size. 

I should keep focusing on getting a better amp so that when I do go cs 7 I’m actually able to play them.
