With a mid scoop like that I kind of want to know what you're listening on? How overblown are the mids on your system that you're going to be scooping it out like that? Did you A/B it with flat speakers or are you just going with sounds good to me? I also keep everything flat because I have a pair of reference monitors I use 80% of the time. I use ath-mx50's for the rest which kinda hype the bass and mids slightly but I'm used to how they sound so it's not an issue to me. I especially take issue with the notch at 500hz, you're taking out all of the bassy goodness that supports the sub-bass which you're leaving untouched, seriously the amount of goodness in that 500hz region is phenomenal and I don't understand why you'd remove it. If you're EQing for general hifi sets, I'd drop the 30hz bass slightly because that's just going to crap out on most speakers and I'd notch out some of the ultra high end shit you can't hear/sounds sharp. I'd leave everything else untouched.
