Thanks for the replies, I read the audioholics riser/bass trap article, interesting. Regarding the sub crawl, would it be of any benefit if I put the sub ON my listening chair then do the crawl? Also, should it be facing the front or back during the test? Cuz I noticed that if I squat or sit in my listening position, the bass changes a lot. I have my sub a fourth of my sidewall length from my front wall. Corner load gave very deep but boomy, muddy, slow bass.
