I'm running two thieles; one with a EVM12L and one with an Eminence Delta Pro 12A. The Delta Pro has a similar character as the EV, but is a bit warmer sounding on the high end. It also has a lower frequency response than the EV. I really like the combination of the two. The EV is bright and clear, and the Delta Pro is fat, deep, and tight. I also recently added poly-fill stuffing to the inside walls of my thiele cabs and it made the bass response noticably fatter, tighter, and less boomy. I highly recommend trying this for tighter bass in your sealed or ported cabinets.
