That is one reason I never sold my CS6 as the bottom end has a lot of punch. Not to say the rest of the frequecies dont deliver but you have to spend a conciderable amount of mony to get that.
Same with my CS7.2 but even more on bottom end. I/ve heard speakers at 2-3 times that price point that did not have that slam in bottom end like the CS7.2
Also agree with what has been said about the CS 2.7. They have a rock solid bottom end for a speaker that size.
these speakers I picked up? they seem to look a lot like Thiels but they have no markings and I can't match them to any of the models provided in the links above.
