I had a real challenge integrating a pair of JL Audio F113V2 subs into my system, as the room had this "single note" it added to the music (regardless of what the bass player was playing), not a problem before I added the subs.
I found that moving the subs to a position in the center of the room, behind my sofa (and listening position) solved most of the "room issues", but the visceral listening experience was "off"...the tonality of the bass was not "directional", but the "feel" of the bass came from behind, while the music came from in front of my listening position.
Ten bass traps later, I positioned the pair of subs right next to the main speakers and once properly "tuned", all is "good". The sound and feeling generated by my system is "consistent".
