3. Double stronger filter for DeepBass Boost and "that' section.
4. You can check it yourself.. something like this, deep bass boost 100%, 20Hz phase-linear HPF:

5 'i think' Filtering/lowering something like under 20-30Hz
Not sure what the --||-- is supposed to be...

Ditto? The reason I asked is because I really can't tell much of a difference. I don't have / use special tools, only my ears, and very rarely, Breakaway RTA.
As for the deep bass boost and very deep bass distortion protection, has the HPF situation been improved? From what I remember, it is not steep enough and I think I remember that you or some other people were wanting a double HPF.
