I actually do not know the answer to those questions. I basically bought them after I had heard the DIs and Eric promised me these would sound even better. I do know they have the 15 tweeter/midrange arrangement because that was how I ended up going in that direction.
I was primarily interested in HT and was going to go in the direction of the Paradigm Persona speakers which had been the clearest speakers I had heard. I was going for accuracy and clarity as my primary goals. The last speaker I wanted to hear was the Legacy Audio line of speakers since like Tekton, the had a reputation of having much better sound than their price indicated. Basically a giant slayer. To add to that, they used a high quality ribbons and I own a set of Apogee speakers and a set of Final sound electrostats. I think ribbons and electrostats if done right have some of the best sound going. I found a dealer that carried both Legacy and had a set of DIs on the floor so I went to hear them. I did some critical listening between Erics tweeter array and the ribbon tweeter, fully expecting the ribbons to be better.
After listening to the DIs I was going to buy them but since so much of the HT dialogue comes from the center speaker, I asked Eric if he could make me a center that looked like a smaller Ulf turned on it's side. I was after the 15 speaker tweeter/mid arrangement for my center.
That was when Eric mentioned the Ulf mini which were more wallet and room friendly and would match the custom center better. That's what I ended up getting. It will have more bass drivers, but be smaller drivers. It will have the 15 speaker tweeter/ mid arrangement and beyond that I don't know much. I am just trusting Eric here.
