Surrounds for Thiel 3.6 system?

When I had Thiel's (3.6's, then 6.0's) i used an older pair of Thiel SCS's for the rears and a SCS2 for the center. The setup worked really well. Matter of fact I am still using the center and rears with my current setup. You can find the SCS's really cheap if you look around and the SCS2 like Mezmo said for around 5-600$.

I have Thiel 1.5s and an SCS2 in the front, and use the Atlantic Technology 454SR for surrounds. Not an exact match in timbre, but I only notice the difference when cycling pink noise through the channels. For program material, it has always sounded great.

For the Buck, in a dirrect firing monitor, I think the NHT 1.5 monitor (mounted properly), is a superb sonic match with the 3.6's! I've had Thiel 2.3's and 1.5's, as well as the NHT 1.5's, And, I think mounted properly, this would be a very close (and cheep) match for the $ ($600 retail for the NHT's). While the 1.5's aren't quite as dynamic as the NHT 1.5's (you could get dynamight results if you, say, rolled the bass off to the NHT's at about 60-80hz!!!

Hoggen,
I have a pair of Thiel original SCS which were designed specificaly for surround. I had a matching center but later sold it. They were matched with a pair of 22's until I sold those as well. The SCS is designed to be placed against the wall. They are very heavy for wall mounting but is possible if you anchor into a stud. Typical Thiel quality, a 2-way coaxial design which is ideal for surround. They are in black ash and in very good condition. Let me know.

I'm using Paradigm Reference ADPs with my CS7.2s and don't feel the need to upgrade. They blend well with the Thiels and provide a nice wrap around effect that I didn't get when using a pair of Matrix 805s. The ADPs are dipoles which mount on the wall up and out of the way. They retail for 900, but you can usually get a good discount on Paradigms.
