Really not my experience at all - I have a fairly growly bass and have not had to push the highs at all.
If anything I would bump the lows on a bigger stage if we ever play one!
I agree about bumping the bass, the cabs have plenty of high mids and growl as you state, they are not dark sounding in those frequencies, I just miss alot of air with theses cabs, they seem very flat and bland sounding, and yes I also had too eq it alot to get a decent sound, bass boost + hi pass and some scooping. However for those who want a PA monitor type of sound I understand the appeal.
