Something about Thiel CS 3.7

Hello Guys,
I own since ten years the Thiel CS 2.4 (not SE) and I'm still happy with them but someone offered me the Thiel CS 3.7 as change with some added money.
Theorically should be an improvment respect my 2.4 expecially regarding the easyest load .. my 2.4 run with Primare A32 solid state amp.. that does a good job on them.
The 3.7 reading specs has 90db efficiency and 4 ohm load with a minimum around 2.3ohm while my 2.4 87db same 4 ohm load but a deep around 1.2 ohm .. not easy for amps.
Someone here tried both? .. and what do you think about?
Thanks in advance for your reply!

  1. strongly agree, seek out the recommended Thiel thread. Rob at coherentsource has what parts he has, would be good to touch base with him on what he has for both. Some parts are now sadly unobtainable. There are a wealth of friendly folks on that thread.
  2. best to you
I agree with Dweller.....they are excellent speakers and deserve the best input you can provide.
@georgehifi. You should see how ugly mine look with my custom paint job. My wife is not a fan of the looks.
Yep, magic sounding, but they're a speaker only the mother could like, and he's no longer with us, rip Jim.
Cheers George
Yes RIP Jim Thiel...what a legacy of great speakers he left behind.
