You actually don't name the reason why they cannot be EQ'd. The only real reason for this is a high level of distortions in sub-bass region. But as I can see this is not the case of Grado SR60e. For me it's seems like they can be effectively EQ'ed in this region (10 dB on 30 Hz should be enough).
I know that's the GS2000 but same principle. It should similar or worse for the SR60, if anything.
Oratory1990's EQ profiles do not boost sub-bass in these headphones (see also Superlux 668B or SHP9500) because of distortion and because it would require too much pre-amp gain.
