I evaluated both the DE250 and DE500 drivers, and liked them both. The DE250 sounded a little smoother to me, but that may have been because I knew the DE500 had a titanium diaphragm. They actually measure pretty much the same. The DE500 is very well behaved, in my opinion. It also has a neodymium magnet. But the DE250 is still my favorite of the two.
There is one area that I'm still evaluating. That is long term reliability. I have used Eminence and JBL compression drivers for years and I know what to expect from them in just about every situation. They are very durable, handle power well, and last a long time. I expect a PSD2002 or 2426 to last a lifetime. The B&C drivers are relatively new for me, and I am wondering how the polyimide diaphragms (used in the DE250) will hold up over the years. This has yet to be seen.
