Why not use an EQ then?
I did ^_^.
the punch (80hz and above) is actually good enough for me. I'm a fake basshead and get used to the level of bass after a few minutes on the er4, what I miss compared to fullsize phones is some serious rumble (60hz and under). and that I couldn't get without making a mess out of those poor er4s.
boosting the sub bass requires a huge boost for little effect. +5db doesn't sound at all like a +5db. and It seems to affect the mids and trebles long before I can get a satisfying level of rumble. so in the end I used only very little boost to keep high freqs at an er4 quality level. as after all, I didn't buy the er4 to make them sound like my IE80.
anyway EQing down a small part always gave me better results than trying to boost something(and I'm not even talking about clipping).
in any case, I don't think it can work on a wide enough range. and I don't think any BA can, single or multi driver. multi BAs seem to give an overall more satisfying result when the crossovers are well done, but really they usually amputate the trebles after 13 or 14khz and end up humiliated by the trebles of the er4. I really don't know why, but that's what I've heard consistently over the years. 1BA lack of sub bass extension, multi BA lack of treble extension.
