Then you’d like them more, but I wouldn’t. Everyone has different tastes when it comes to bass, but I wouldn’t want any more than what they already have.
I also like what my ER4SR does for bass when I give them a +3dB 125hz bass shelf, but they still don’t do sub-bass very well at all. They have a super fast mid-bass with plenty of snap, but still have no authority under 40hz. There is only so much a single BA can do. The Aful P8 fixes that.
Although the ER4SR measures with a decently flat and extended sub-bass there is really no power behind it.
