@tomthiel. Too bad about the CS 2's. From time to time I see reasonably nice examples being offered for sale for about a couple of hundred bucks. Shari once told me that they were Thiel's most reliable product. The sensitivity being a fairly reasonable 87 dB is enhanced with a very smooth (and fairly kind load for Thiel's) 6 Ohm nominal / 5 Ohm minimum impedance. All in all easy to drive. This and bass that drops cleanly to below 40 Hz. Other than the trick baffle/grill (which perhaps fortunately is a bit difficult to remove) it seems like a rather simple straightforward design of rather exceptional execution, that could be easily maintained for a long time. And no need for stands!, ha. All told at present prices these might be the best used speaker values currently available. These could make for great entry into the hobby, gift setup, charitable contribution, etc.. I'm sure many of these were sold. It almost becomes a social consideration as to whether or not to let these go to waste.
Lest I mislead anyone about the ease of powering them, let me say that while from a technical perspective they are very accommodating, sonically they can be more discriminating.
