When I'm letting the Audyssey MultEQ XT do its calibration for my 7.1 setup (Epic 80-600 with QS8s and M80 center), what should I do with the settings of the EP600? Do I give it full range and let the Audyssey figure it out and roll it off, or should I put the crossover at 60-80? No copping out and saying "try it both ways and use whichever sounds best to you". Thanks! - Nuke

I would let the Audyssey do it's thing and modify from there.

Try both ways and use whichever sounds best for you.
Seriously, that's really the best answer. If it wasn't an EP600 (or 500 or 400), I'd say put it at bypass, but there's been some indication that it sounds better with the crossover set.

The denon 3808 manual says to put the sub's crossover to bypass during the set up.
for my 500 I had the crossover set to bypass with the volume at about 50% during the audessey set up.

That's how I did mine as well with regards to crossover. Trim to "flat". It doesn't really matter where you set the volume, in my experience, Audyssey tames it to -12 no matter what.
After the Audyssey does it's thing, adjust the sub volume to taste. Don't worry about damaging the driver by overdriving it, the DSP prevents that, a pretty reassuring feature!

Nuke, if you're using the crossover in the receiver, either set manually or by Odyssey, there's still no good reason in my view to also insert the internal sub variable low pass filter. Set it on bypass.

Ignore what Audessey suggests for subwoofer settings. It like all auto-equalizers are inaccurate for frequencies below 100hz. Audessey is one of the worst in this regard. Better to set up delay, level, crossovers manually.

John, what you're saying is really unfortunate. The only reason I would even consider buying an Audyssey-equipped Denon is to manage frequencies below 300Hz. If Audyssey can't do this, in my mind it's worthless.

Mojo,
No EQ program is perfect. Audysey will do just fine for gettting you started and most comsumers will be quite happy, considering they don't even know what an SPL meter is. I rather like what it did with my set up and after further set up with a meter and Avia / DVE test disks, I found that I changed very little.

I can see how Audessey may help smooth FR in the upper frequencies but there is no way it can calculate optimal settings down low. The physics involved make it very difficult for an automated program with limited processing power to do well. Fixing FR problems with automatic electronic correction is a tricky proposition requiring huge amounts of dedicated processing power to calcualte iterations.
I have rarely seen any automated program which actually set equalization/delay/crossovers correctly for subwoofers. Its actually refreshing to buy equalizers (DEQ2496) with auto-programs where the manufactuer(Behringer) specifically warns not to use such programs for frequencies less than 100hz.
The fact that the Audessey programs in receivers are marketed as one stop silver bullets is disingeneous to me. To do the job properly across all frequencies requires far more processing power than you find in the typical receiver. Indeed even to address correction strictly in the lower frequencies is a formidable task. The Velodyne SMS-1 for example does a reasonable job up to 200hz but limits resolution to 1/3 octave because of processing limitations. Meridian and Lexicon limit their scope to only addressing long decay times rather than flat FR below 250Hz. Interestingly both of these companies recommend using room treatments to address flat FR rather than use equalization because of the limitations in the devices.
One always gets better results by doing such equalization and delay settings manually.
