@Zapp_Fan in the portable, contemporary market your approach makes sense and I would argue that for the reason you noted, the ability to EQ frequencies after the fact, that it is quite acceptable to allow a little extra bass energy into a signature. There are already system wide equalizers that can be used with Android and iOS phones if I'm not mistaken; however, if Aiwa were to author just such an app (hopefully a parametric equalizer) that would be ideal.
