Subwoofer with Thiel 2.4s?


Hi all, I'm in the process of building a new system and am considering adding a sub to my Thiel system. I'd love to get one of the Smart Subs, but they're just too damn expensive to fit into the budget. Any opinions on the other alternatives? Although I do use the system for TV and occasional movies, I'm really only interested in 2 channel.

I've read good things about the REL Strata III, but would like to hear other's opinions on the available < $1000 (used) options.

I'm a 2 subbed (2 subster? "sub" stantial?) listener as I scored another REL from the same era as my Q150e…(a Q108II). 2 subs actually help remove some of the corner roll off boom by introducing an in-phase signal to the bass that escapes along the wall from the other sub to meet up and MODE so to speak. The Q era REL subs have lots of adjustability so integration into the room isn't so difficult at all…and you can buy these damn things pretty cheap (both of mine are perfect and cost about 200 bucks each…you simply have to wait for one to come along).
"I love and endorse REL subwoofer(s). Happy Listening!" 

Are all the election spots rubbing off on you Jafant . I endorse this post !
Reviving an older thread here;
hope you guys are still enjoying the CS 2.4 and a REL or SmartSub.

Happy Listening!
Just received a pair of SVS SB2000 subs to integrate with my 2.4s. My plan is to have the 2.4s well into the room and have the subs located in the same plane just inside the mains. Because I will hook them up so that the preamp will line L and R into each sub, which will fixed cross the line outs to the monoblocks at 80 Hz (12 dB per octave drop, and which will now be working less hard), it will be interesting to see where the ideal crossover adjustment betwen 50 Hz (the lowest point on the subs) and 80 Hz for the subs will land. My guess is somewhere in the 50-60 Hz range. I’ll let you know how they work out.
