I can't think of any reason NOT to use the sub.

I think that any time a system sounds better with the sub turned off, then it simply must not be setup properly in the first place. It took me a good amount of time until I found the best settings and placement required to integrate my sub with the rest of my system, and now there is never a time that I would want to turn it off.

I use 80hz crossover for movies, and 60hz for 2 channel listening (I used to use 80hz for 2 channel with my m-22s, 60hz for my M-60s now). I use an Outlaw ICBM for my bass management, and for the rest of the channels, I have my vp150 set to 100hz and QS-8's set to 80hz.



Here's a couple reasons...

1) You don't have a really good sub (a bad sub sounds horrible with music
2) You have no bass management (or very little)
3) You have shared walls/floors with neighbors
4) You prefer the sound of music without the added depth of a sub
