That this Velo can keep up with and enhance the openness of the Magnepan 3.7's and the other speakers mentioned in this thread says a lot about its velocity, cone / cabinet resonance and dynamics. I'm running my DD15+ with Dynaudio C1's right now and it keeps up with them. Or are the C1's trying to keep up with the Velo?) a very fast sub here.
I run the C1's by themselves and they are very pure and natural with very present base. Very deep, realistic soundstage. Then, I do the crazy thing of setting the crossover all the way up to 200hz on the Velo and setting the volume very low (2 to 6 for jazz and 6-12 for rock) and whaalaaa, the soundstage opens up and every aspect of the instruments / vocals / air is enhanced. Try this technique and let me know if its just me or does this happen in your set up as well.
Some ramblings: Now I want to try two DD12+'s in my room! Overkill? Certainly. Crazy? Never!!! I too believe 2 subs are better in a good listening room. My room has five walls, an open entry way, a strangely vaulted ceiling, very thick walls and floor and every component is suspended on foam layers. What does all that do? Something, I'm sure. This upgradeitis can become dilusional. Not knowing if there is something that sounds better is a fun thing and drives us. The biggest hurdle for me is telling my wife, "Yes dear, those have always been there" and getting away with it. Once I actually covered a new sub with a table cloth and told her it was a new side table, placing a lamp, etc on it. That worked for a couple of weeks. I don't want to talk about what happened next though.
