      Yes, NHT buyout. Zaph has measurements on his blog. They look like good woofers.

        The CSX stuff was always excellent. Those are a very good deal. The frames are a bit on the flimsy side, but the motor and cone produce the smooth response with low distortion akin to the HDS line.

          Because the HDS are not too far removed from "CSX guts in nicer frame."

            Not the one on Zaph's blog. This is from the NHT Super Audio series. Specifically the dual 5-1/4" MTM center channel. I have a pair out in the garage I scavenged from that center channel. Both of mine measured closer to 0.6 Q, though. The center was a sealed design. Nice woofers, with the exception that the frames and the shielding cup are very, very, very, very ringy and it showed up in my impedance sweep. The ones Zaph tested had an o-ring on the shielding cup, so I grabbed one at work that would fit on the cup, and it still rings. This will need to be addressed to make sure it can be used to it's full potential.
            Don't listen to me - I have not sold any $150,000 speakers.

              If you look at the larger picture of the back of the driver PE just got in the numbers are 850443 and 1-11-081-1. I think they are the same drivers I sent to Zaph to test.
              PE's QTS looks a little different though.

                They are the same model number that Zaph lists on his website. I did see the thing about the rubber O-ring on the shielding cup. Kind of interesting. Maybe you could just take the shielding cup off if you don't need it?

                  Yes you are correct, I apologize. I have a pair of those as well and they were sitting next to my other pair :S

                    I've been trying to sell my pair but no takers, and mine have the o-rings.

                    No need to apologize. Any build plans for your pair Johnny?

                        One has been mounted. The other one I am listening to now. A design by Jeff B. and Mark K. using the Vifa DQ25 tweeter. Wolf has a design for that driver pair too, I wanted to give a listen. I bought them from the NHT clearance page years ago. Very lightly used. $30 for the pair plus shipping. See my moving sale in the classifieds here at PETT.

                            I don't think I would try too hard. A person could bend the frame or chip the magnet. The o-ring on mine does the job.

                              If they are anything like these, the shield comes off very easily. I bought some of these during a PE buyout a few years ago and a number of them had the shield and bucking magnet fall off during shipping.
