Thiel SS2.2 added a new dimension

Definitely agree. It just extends the 3.7s into a full range Class A speaker :)

I love how Thiel took the guesswork out of integrating subs. So microphone needed. No crawling needed. Just dial in the distance the sub is from the nearest wall and voila. I use the S1 integrator which gives a bit more flexibility but does require I read the specs off the power amp and speaker manual. :)

In the past, I've found it hard to dial in just the right amount. What's ok for one track may be off for another. I get that even with Martin Logan's integrated sub unit on their electrostats.

Anyway I ended up with two of the SS2.2s :)

I have demoed a pair. Very nice but the price has always stopped me from buying them.

You have to stop viewing it as a subwoofer but a way of extending a limited range Class A speaker into a full range Class A speaker :)

Will the SS2.2 complement, say, the CS 2.2 or CS 2.4?

Happy Listening!

I was using the SS2 with the 2.4 :)

It does.

Nice, thanks for the post, would love to hear that setup.

Very late comer to this thread, sorry!

I have a SS2.2, centered between my 2.7s, fed via a  PX05 passive crossover configured for the 2.7s.   The PX05 is fed from my Bryston 4BSST2.

I'll second the above thought that the SS2.2 is not an AV "punch you in the gut" type subwoofer, but does extend the apparent low frequency response of the 2.7s, but without drawing attention to the sub, per se.  

Disclaimer: I listen to a range of classical music, but not heavy metal or rock. I'm not set up for AV - - just a 2 channel stereo system.
