FWIW, I should add that two of these drivers were used in a DNA2 build of mine, and I was completely happy.
 Then, one fine day, a customer Gave me brand new Scan Speak drivers that are very expensive so I tried them in the DNA2 cabinets. Yah, so new project that will continue to be expensive it will become a 2 way speaker.
Here is another shot. Just different to see up close the voice coil former and suspension. Mark Audio makes a big thing about this aspect of the drivers.
