When I first got my 706 last year, I discovered this website and read the Audyssey Setup Guide several times. Really helpful document.
Following some of your suggestions, I pulled the center speaker forward a bit on the shelf. While not low to ground, the center speakers tweeters are several inches lower than seating ear level position. I lowered the gain on the sub to around 10:00. I set LFE LPP to 120 Hz. I am also experimenting with the Audyssey results (crossover and trim levels), and setting crossovers of front/center/surround to 80Hz.
After making the gain adjustment on the sub and repeating the Audyssey setup, I got the following results (cutoff/trim):
Should I leave Dynamic EQ on or off? What exactly does it do?
As I said in my original post, while I don't mind a wide dynamic range if that's how a movie is intended to be, I want clear and intelligable dialogue.

I see two problems with your Audyssey results.
The first problem is that the subwoofer trim level is at the very bottom of the adjustment range. This indicates that the level control on the sub is set too high and the 706 may not be able to turn the trim level down enough to compensate. The overall level of the sub may be too high, causing some of the problems you are experiencing. Set the level control on the sub to between 9 and 11 o'clock. No higher. Make sure the crossover on the sub is either bypassed or set as high as possible. Set the LFE LPF on the 706 to 120 Hz.
The second problem I see is that your crossovers appear too low. When you rerun Audyssey, if you get similar crossover results, set the speaker crossovers in the speaker setup menu to 80 Hz. The sub will do a better job of handing frequencies below 80 Hz than the other speakers will. Just remember: it is Ok to raise
a speaker's crossover point, but you never want to lower it
Let us know how things go after following these recommendations.
