Thanks for your answer Thomas,
I do see your point but it was lateral bouncing stuff from the left speaker what got me worried. I forgot to mention that I do have wall treatment on side and back walls (basically 2″ insulation with 1″ separation from the wall), a thick rug on the floor and a bit of acoustic treatment on the ceiling fist reflection points.
Bass response below crossover frequency is not a problem, I do have two 12″ subs in opposite sides of the room and I get a nice flat-ish response with plenty of tactile feel. I was more worried about the stuff going on above the crossover.
