Sub and LFE settings on Surround Processor

I am trying to tweak my home theater subs and am intertested in the groups experience with the sub and lfe settings. My surround processor has the capability of adjusting both for a variety of equipment including dvd,dish, cd ect. I am trying to get a feel for the balance between lfe and sub as well as the Hz for the crossover. Presently I have theater set 80Hz and the music at 60Hz. I would appreciate any input.

I wasted a lot of time on this issue, but finally realized that different recordings have been mastered in such different ways that there really is no best setting. I have a nominal setting that comes up automatically when I turn things on, but if it doesn't sound right I am quick to adjust the settings.

My speakers are Magnepan 1.6 which are not known for LF response, but, to my surprise, actually do measure flat to about 40 Hz. Accordingly I started out with the SW crossover at 65 Hz. However, I now obtain better results at 90Hz. I conclude that, although the MG 1.6 can do it down to 40 Hz, they are working too hard at it. Moving the crossover frequency up to 90 Hz gets rid of a lot of diaphram flapping around which doubtless degrades fidelity at higher frequencies. What I am suggesting is that the crossover criteria can be how high your SW can go (with good sound) instead of how low your main speakers can go.
I suggest you experiment a bit.
