Pick up an old ashly analog parametric.They are very user frienly.This will remove the bass bumps.Digital parametrics are difficult for the beginners.Get yourself a test disc and a ratshack SPL meter.Put the sub where it sounds best and go from there.Good luck!
Boomy bass in home theater room
I have a Martin Logan/Adcom home theater system in a 14' square room (concrete floor (no basement) with typical wood stud/drywall construction). I'm using a single, Infinity 12", 300 watt (RMS) subwoofer. The room is treated with 24, 2'x2' (3" thick) acoustic foam in various wall locations. The bass is boomy, especially in the mid-bass region. I can't change the room. When you get done laughing, care to offer some realistic suggesstions?
