I special ordered a pair of Double Impacts with ribbon tweeters in place of the array of dome tweeters because I generally prefer ribbons or AMTs, and I was unable to hear the dome array before purchasing. I didn't spring for the Mumford ribbons, but something a bit less expensive; and Eric still said it amounted to an "upgrade." He was also excited at the opportunity the use of the ribbons gave him to lower the crossover point, which he thought might provide a smoother transition between the two midrange and high-end. I'm no expert on the technical stuff; I'm just reporting what Eric told me. Of course, I know he's a good salesman, but I was clearly going to buy the speakers one way or the other. So, he had no reason to prevaricate. And he certainly has a reputation for honesty.
I've had the speakers for several months now (at least five or six), and I love them. Obviously, I have no basis for comparing them to the regular DIs, but I'm more than fine with what I've got.
