Buy a used pair of 7.2's, the CS6 is the most underwhelming of the Thiel models as Stevecham mentioned the CS6 is the newest version of the 3.6 as its driver complement is essentially identical to the 3.6 just the price tag isn't. Fact is it had always been my opinion the CS3.6 was better than the 6.
It is likely the CS3.7 will cost nearly what the CS6 does as the price of the 2 series in the form of the diminutive 2.4 has now matched the recent pricing of the 3.6.
I disagree with Stevecham the CS2.4 with a <$1500 subwoofer
would embarrass the CS6 with its coherency and considerably improved mid driver. The real value though is a CS7.2 which can be had for $4K used and in good condition. In particular get an upgraded 7.0...7.2 with the casted baffle. As long as its not cracked it makes for a better and much much heavier speaker :). My $.02 on the matter
