I'm a strong proponent for Dirac Live room correction, over standard PEQ of frequency response. The time-domain correction is an incredible improvement, that pretty much everyone loves once they hear it.
miniDSP's boxes are the most convenient way to add Dirac to a speaker setup, although you can find Dirac integrated into other products from brands like NAD, Bryston, Emotiva, Arcam, and AudioControl.
There are other products besides Dirac that offer similar functionality, but none that are as easy to use and integrate into an existing system in terms of hardware or software in my experience.
