Well, I'm going to post this again and ask that everyone try it. I'm using triple flange as that seems to be most common. Green filters for this one, this will not sound proper with any other filter.
Get those triple flange nice and deep and sealed and try this out. It should sound identical with any eq app that uses q values. I've tried a few and even used my ab switch to compare to see how the eq apps differed. When the settings were identical the sound was identical. The only exception is low shelf/high pass filters. Those seemed to vary based on implementation or simply lacking those. No problem, I didn't use any.
I've really put a lot of effort into this during critical listening with my studio monitor speakers which are extremely flat alesis monitors. I used graphs to help isolate the necessary frequencies and whatnot. Most of the adjustments are very minor (which says A LOT about the er4s), but all together they even out and open up the treble noticeably. The bass sections are the most prominent, but isolated completely to the sub bass region, so there should be ZERO mid bass masking or anything to detract at all from the high frequencies. Get used to the sound for a bit and see how you like it. It sounds very flat to my ears and makes me not want to listen to anything else. ha. Songs with clean low end sound amazingly clean and clear, while songs with thumping bass portray the thump and deep impact properly without masking anything. I hope you like it. I'd love some feedback.
The last thing I'll say is that the great thing about this eq is, while I prefer the additional accuracy, if you don't want to deal with all the bands, you can just use the lowest three bass bands and it sounds excellent. The other bands are more minor refinements, but really do give things a more realistic room presence and stuff like that. Orchestras sound amazing. You could even roll the three bass bands into one band with a wider q, but I used three to get the exact curvature. Anyway, here it is:
