i'm trying to make sense of sub xover in bass management. in my HT set up i have my mains and surrounds set on large and my center set on small (this set up sounds best to me after experimenting) my center only goes down to 90hz. my mains reach down to 40hz and my yamaha reciever is set for BOTH so that my sub and mains share the bass load. i have heard so many conflicting opinions regarding the way to set the sub xover. some say leave it set at 120hz to let the sub pick up any signal up to that point. others say set the sub at THX referance of 80hz. others say set the xover at your recievers xover setting which would be 90hz. some say if the sub duplicates the mains in some frequencies this will reinforce that frequency, others say it will cancel each other out and give you less bass. can anyone help me make heads or tails of this?
... be careful about speaker polarity. Double check you do not accidentally wire anything out of phase as it leads to very wierd effects. Otherwise there is no magic number. I'm still fiddling, sorry, tweaking, our system. Sub placement makes a big difference as can using two subs instead of one.Peace at AA

hi,
you want to hear a balanced presentation, with no octave obviously louder or softer. There is no simple answer here. IMHO, 120 hz is only for
systems designed to work that way. In those systems the sub is really a bass module that typically can't go as low, or as loud, as a real sub.
The two things to try first are to run the stereo pair full, and move the sub around the room trying to get a good balance. The second thing is to set the stereo pair on THX, and move the sub around.
What i did was to get a cheap filter that rolls off anything above 52 or 54 hz. This has worked pretty well, but it is a case where you just have to see what sounds good.If i had my druthers, i would roll off a little lower, but my stereo speakers have plenty of bass.
