6dB doubles the SPL, 10dB doubles the perceived loudness. Matching the equal loudness curve? That's madness, I'd like to see how ear bleeding it would be for you if you did the same to high frequencies. Let's see how the FR looks after your bass boost.
(FA-003's FR graph from innerfidelity, which may or may not be indicative of HM5's FR, just for illustration)
Since I don't know how much 20Hz is boosted, I have made the assumption that frequencies at and below 60Hz are increased by the same amount. This would underestimate the sub-bass region if you gradually increased everything below 60Hz beyond the reference point. The added pink curve is a 6dB increase whereas the green curve is a 9dB increase, both at 60Hz. They were drawn by hand.
Have you tried lowering all the other frequencies by 1 dB except 40Hz and below? I think if the gain is adjusted for the boost there shouldn't be any distortion. But it seems like you know what you're doing.
aahh. so the 9db increase wasn't that bad then? but i'll stick to 6. works for all music i listen to.
and for illustrative purposes, the 6 db low shelf at 60 hz and 1.8 bandwidth looks more like only about 40 hz and below reach the 6 db increase. 40 hz to 100 hz gradually and equally reduce in db increase from 6 to 0. here. a picture is worth a thousand words, they say.
and yes. i did adjust for the boost. (-5.5)
and no. i wouldn't try it for higher frequencies.
HOPE YOU GUYS GET YOURS SOON.
