I am small fry here I know. And I also understand that most of the systems that we have are EQ'ed. But personally, I think having as little in the chain to alter the sound is a good thing. For the full range speakers I probably would say very little or maybe no eq at all. For the ones with subs, I think just enough eq to help out any rough spots where they are being crossed over or as was suggested, any nasty peaks in the room, but that's it. I would rather hear what the speaker can do, warts and all, rather than having an EQ maybe cover up issues the speaker may have. But hey, I am on the low end of spectrum here so what ever you guys choose to do is fine with me.
