subwoofer crossover- lowest is best almost always?


In my experiences with subwoofers, I have found that lowest setting has always given me the least colored bass response as well as the tightest.  I have found in almost all cases that anything remotely close to crossing over at the speaker frequency seems to overblow the bass almost every time and have a negative effect on the overall sound most noticible with digital.  It seems that any other setting is just trying to compensate resulting in sound that does not sound right. Albeit some may think that systems that do not crank the subwoofer as being thin sounding. Well, I think that depends ultimately on placement and setup of speakers and sub.  Just curious to what others think.

OP-

what brand sub do you use? Much will depend on the branding.
Otherwise, 80Hz is a good place to start tweaking to taste.
My crossover is set at 25 hz.  My speaker crossover is 55.  It does not sound like their is hole in the music.  In fact, the opposite.  Piano sounds full and real.  Voices are more intimate sounding.  I know that everyone room is different but I truly believe in almost any circumstance that I have had with sub's is less is more .  I can see why someone would not want one at all. I use a rel strata 3 currently.
My Maggies have almost nothing below 100hz.  I'm crossing over higher for them than any mini monitor I've ever used.

I used subwoofers for many years but could never completely eradicate occasional room node or crossover aberrations. As also noted by wolf_garcia, different recordings also contain quite wide variances in bass levels which can be extremely annoying. I do not want to constantly adjust settings on the subs to be able to enjoy music.

Several years ago when I heard a friends system using a DEQX processor & two subs I could not believe, firstly the clarity of the overall music, but mostly the absolute slam and transparency of the bass and no sense of room nodes or crossover point. I had heard nothing like it before.

I added DEQX to my setup early 2012 and, likewise I now have no issues whatsoever with twin sub bass integration. I have also created four configurations, selectable by remote, with 2-3 my ’normal’ listening setup and 1 for bass light music, 4 for bass heavy. In that way I can choose the appropriate setting and whatever type of music is played, bass is as near perfect as I could ever want.
