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 have Revel Studios which do have a fairly good bass response at the low end. My problem is that my system allows me to control the level of the LFE and Subs separately as well as the Hz level. This allows three potential adjustment for each profile. Eldartford's point that I should take it up to the highest potential level is good for a try, but actually I have been going in the other direction. My speakers do pretty good and my feeling is at least on music to use them to the point where they don't pick up the low end that the subs could handle. On movies I don't want to kill the mains when I have two subs to handle all the kaboom crash stuff.
Ken you should run your Revel mains full range for music. If you can control the slope of the roll off for the low frequencies [6db 12db 18db 24db] then you set the slope at the slowest setting provided. 6db being slower than 12db etc. Usually the slower the slope the lower the frequency setting should be placed, in your case 12db. I would place freq hz at 40 to 45hz. One issue that is in question and the hardest to measure and also to cure is accoustic phase relationships and wave launch of all the drivers. Wow. Ken remember I have an RTA. I believe you live not to far from me. You supply the beverages?
Tom what a reality. Bring the RTA I'll supply whatever. Moving the subs more to corners did cure the overload on movies.
