I've never tried the DV-77's, but Governors and V12's are attrocious. They can be made to sound OK in the room, but as soon as you swap in some good Celestions in there, it's night and day.
I always hear this weird Eminence thing to the mids in every clip out there too, and it's VERY easy to recognize the second you throw an SM57 in front of them. Some have it more than others. DV-77's seem a bit easier on that regard (but it's still there if you listen closely), but Governors are BAD. It almost sound as there's something going on with the phase, even if you're just using a single speaker and a single mic. Maybe an SM57 is not the right mic for Eminence speakers. But honestly, if a speaker doesn't sound good through an SM57, it just isn't a good speaker, IMO.
So I just stay away from Eminence speakers, really. Especially if I intend to throw a mic in front.
