I have been trying to configure it and I have it at 75db as well as the rest of my speakers.

You can also run the sub a little higher (78db-80db instead of 75db)

In my opinion I think it should be harder hitting than it is, am I doing something wrong? ... I think this thing should be hitting hard...

A couple of things here:

First, your ears need to adjust to the new sound (that's what happened to me after I build my Sonosub), and it will take some time for the sub to break in; then it will sound better.

Second, Did you use a movie with a lot of bass and that you watched before with the old sub??? ...sometimes the material doesn't have a lot of bass specially OTA or SAT programming :yes:
