I don't claim it's perfect, but i use multiple graphs from multiple sources, comparisons to studio monitor speakers and also my general experience mixing and mastering music.
I've isolated the general regions that each graph seems to agree deviates from the reference curve. I've then gently adjusted those frequencies to come to or closer to flat. I adjusted the bass based on graphs, but have tweaked it up and down, as that varies more with tips. I think i found a level/curve that is fairly accurate and works with each tip. Sort of an average.
Having compared this with studio monitors that i have seen measure flat, as well as other speakers, it is very apparent that it is closer to flat in a studio monitor sense. With all this said, the changes are very small. A good way to hear them is to use my eq without the bass adjustment and switch between eq and no eq. You should hear the treble open up a bit and sound mote natural and transparent. Or eq with the bass and treble adjustments and switch between that and the bass eq without treble adjustments. Either way.
The only catch would be changes based on insertion depth, however the areas i've adjusted seem to appear pretty consistently across users and graphs. And if you have a proper depth per rin's suggestion, there should be minimal to no insertion depth differences between users.
Lastly, not everyone agrees on bass level. Some say the +6db should apply. I'm not sure which i prefer, but i've aimed for a balanced bass level somewhere between that sounds transparent. Techno has appropriate thump and sub bass, while other lighter music will see no bleed or negative affect from the bass at all.
I recommend people try it for a while and see what they think. At a minimum my bass level is now a single point (i'll post it again later) so it is easy to adjust level if you desire... :-)
Hope that answers your question. :-) More than anything, i'm simply pursuing what i consider the perfect response. Everyone may not agree, but for me this is strongly related to a flat graphed response similar to OW.Edited by luisdent - 3/18/14 at 7:11am
