A lot of great in fo here, and yep generally speaking lower = less upper in your chest bass, and a tighter deeper foundation shaking bass.
But as mentioned, equipment, room etc all com into play.
I would adjust 1st from the preamp , this is an active crossover setting and thus limits what gets to the sub, less to filter the better. Then try various settings to get what you like.
Also you may find on movies etc you may alter the settings from stereo , surround sound sacd etc.
good luck
