Funny thing just happened. Well let me first say I am using an svs 20-39 and my receiver has a 100Hz fixed xo. Ok, so anyway I was doing a frequency sweep with THX optimode's 200-20Hz sweep and an spl meter, and I discovered a drop off around the point in which the sub is taking over. It was only a couple decibels but it was there. Well out of curiosity I turned the subs xo on and set it at 80Hz and reran the sweep expecting to find a loss of information between 80-100Hz. Instead I was shocked to find the drop off was gone it seemed much flatter through out. Although still a little variance it was not as drastic as it had been with the sub xo bypassed. I was kind of baffled so I messed around with it some more and kept finding the same results.
One other thing I'd like to mention is, as the sweep neared 20Hz. There was a 4-6 db increase. This is because I run my sub 4-6 db "hot" correct?
If anyone will enlighten me I will be much appreciative.
