Thiel Owners

@Jafant, am confident that I am not alone in thinking that there are instances where the CS 2.7 and/or the CS 3.7 would require subwoofers. 
  Utilizing a proper power amp will not unto itself act as an equalizer to yield aural results across the frequency spectrum beyond the scope of a loudspeakers limitations.
 There was a reason that Jim Thiel made other models besides the 2 and later 3 series that had a broader aural frequency spectrum range, as well as a range of subwoofers to facilitate a broader aural frequency range.

unsound,

For that very reason I will be keeping my CS 7.2. As good as my CS2.7 are, they lack the bottom end of the CS 7.2  which delivers in spades. 

Ok, I’m not getting the excitement for Thiel speakers.  I’m listening to some CS1.2’s and find them to be extremely light sounding.  Absolutely no bass whatsoever...

I do recognize the sounstaging is very good; however, they have no meat on the bones.  I’m not looking for deep bass, just looking for something...

Right now, I’m driving them with a Rega Brio...  What am I missing?

The Rega Brio is not enough power. I’d say minimum you need is 100watts into 8ohms that doubles to 200watts at 4ohms. Even that might not be enough.

You will need a much more powerful amplifier. 

And the CS 1.2’s only go down to 52khz. Deep bass is not going to happen with those specs.
