I have heard it said that one should not be able to localize a sub. Is there any truth to this or is it a hideous lie made up in order to keep me tweaking!? Have I been "blessed" with canine-like hearing? No matter what I can tell where the sub is, no mater where it is, what level its set as - even really low, or what crossover is used. I was at the Manchester hifi show this morning and the few rooms with subs in I could, again, tell where it was. Am I a freak? This is the curent response in my room. Does that shed any light on my problem? Crossover is at 80Hz The sub is an SVS SB12+ so its a fairly high quality unit.
