Click on the links in thread the minidsp is highly regarded,{affiliated with DIRAC EQ.} they've also got units you can add between the subs and output to do Eq. as well. Seems like a tedious process the R.E.W. but once you understand it's probably easy to understand the graphs.
The UMIK was my rational on upgrading to an Anthem unit. As It comes with a calibrated Mike and skips most of the hassle.
