I am confused on this and I hope someone can help me. I have dual HSU HO subs and I have used REW and the 1124p to flatten out my response. If I run REW with only one sub playing at a time, REW says that I have -10db of headroom, no matter which sub I play. When I have them both going, REW says I have -5db of headroom.

How come I seem to have less headroom with both subs playing than when I have only one playing at a time? Also, when the headroom number comes up, it is in red with both playing, but in green when either one is playing alone.

Thanks
