I don't know how loud it can go, but it seems that ADAU1701 equalization can iron the response down to 10Hz:
I was using single precision ParamEQ block which apparently was producing some noise at low end so I had to go for double precision PEQ, which in turn seems to be limited to three peaking filters (in ADAU1701). Happy with result so far, I wonder if lower Fs driver would bring any benefits here.
