The system I have is limited by the small room, but I made it work to some degree of success. I need to move to a bigger house. The Thiel CS3.7 is an oldtime fav of mine, and I am glad I finally got it. I should have gotten it years ago, but I listened to people say you need a very large space for them. I know now that there are ways to make any speaker work in a small space.
I bought my CS3.7's used last November and had to replace the 2 COAX drivers with new ones. The woofers were replaced by the previous guy. I had to fix a hole in the COAX fastener to the unit (for vacuum seal). Do some soldering on the crossover. Those were all for screwups by the previous owner. I screwed up the finish due to a mistake on my part and decided to just paint the thing black. The speaker is now in almost new condition except the funky paint job. Either the speaker dies first, or I do before it is replaced in the office.
