well, got the soundcard calibrated and first impressions so far on REW w/ the BFD are very positive!
i have a couple questions

. my xover on my receiver is set to 80hz. my sub extends to 22hz. should i be measuring between say 15hz to 80hz? and also do you guys use the auto filter settings? measure the sub a few times correct and then go with the best result or do you manually tweak? i have not messed with manual tweaking yet.
