Boomy Bass?

so ive been running my torii in my new place for a couple months now. the room is 15'x25' and has a giant window box(about 9'x9'). i've got the room furnished and about 30% of the floor covered by a rug. i put up some ATS fiberglass acoustic panels and have played with the positioning of my speakers. i've got zu omens set up in the basic cardas golden ratio configuration. everything sounds pretty great, but i'm hearing a bit too much boom in the room for my tastes. what are some things i can try to get rid of this?
