I will not be able to do that because there is no place to do so. Only for one sub.

Audyssey set my speakers to small, center to 80, L,R to 120 and surrounds to 90. I have played with the speaker crossovers and set them all to 80 however, I am still having the problem.
The sub volume is set at 0db and the LFE on avr is 120.
I was told not to touch the LFE and leave it at 120.

Is there something that I am missing?

You should never lower the c/o. Lots of info in this FAQ from the Audyssey thread;

I would set the sub to the centermost point available in the front of the room. Roughly a foot from the wall if possible.

Only in two circumstances. One is that the sub is too loud, which distracts the ears focus from where they should be getting directional cues. The other is that too much information above 80Hz is getting to the sub. Fix that by turning down the low pass frequency on the sub amp to 80Hz. That increases the total low pass slope to remove above 80Hz content while having no effect below 80Hz.

I already changed the crossover to 80 on avr.

Im not sure but I think the low pass is different than the crossover.

If you read some of his other posts, you'll see that Bill is a proponent of "doubling up" on low-pass filtering of content. IOW, set the crossover in your AVR to 80Hz and set the LPF on the sub to 80Hz.

I thought if the sub is connected via lfe then the internal crossover is bypassed?

I think* it depends on the sub: In some cases it's by-passed; in some cases, it's user-defeatable; and, in some cases, you max out the setting in order to render the LPF irrelevant.
