Most master volume controls start in negative region (like -60) and move upward toward 0 (and then into the positive region a bit).
If your master volume is different, then set the center channel level to 0 (usually on a scale of -10 to +10), play the test tone for that channel and increase the master volume until the SPL meter reads 75 dB C Slow.
Don't touch the master volume again, and then play the tones for all the other speaker channels and adjust their levels until they are also at 75 dB C Slow.
For the subwoofer, set the channel level to -5 (per the above) and adjust the gain until the meter reads about 74-76 dB C slow (it will fluctuate some). This will have the subwoofer running about 2 dB hot (since it reads a bit low on the bass tone), which most people prefer for HT applications when they are looking for a little more slam/impact.
Experiment with subwoofer location and listening positions , you could be sitting in a null which is robbing the bass of impact and dynamics.
Thanks AV Addition! I do remember doing this back then when first setting up my older sub and it's been like a year so I the refresher was good, even though I have the Audyssey FAQ pinned on one of my browsers. I'm not sure if this is odd for others on this sub, but I was using the y-adapter but then just switched to using the one pin to the LFE/Left and when going thru Audyssey, I would have to turn the gain to about 12:30 or so, b/c if I would turn the gain up more, the Audyssey run would show the sub as -12 which is the farthest back it goes on the AVR. I tried setting the gain to 2 o'clock or higher and of course this sets the sub to -12, so that is too high for me. I guess this depends on room setup so can differ for each person as well as the AVR.
So I ran Audyssey a few times with the phase 0, xover 150 hz (all the way clockwise), and gain about 12:30, and I got the sub to -1.5, which is good. Then when I ran Audyssey all the way thru to the 8 setup points and saved the configuration. When I went back to update the speaker trims with a RS spl, I noticed the sub was always around 68 hz on the meter, so I would have to change it from -1.5 to say +3 (which goes to around 72 hz). I would go up to +4 or +5 so that the meter would be around 75 hz but is that too big of a jump to have to add to the sub trim?
Silly question, but once Audyssey is setup and the trims are set, you're NOT supposed to go and turn the gain on the sub right? If you do, you have to re-run Audyssey, I assume.

I'm in the opposite boat, at least I think. I can hear the low level stuff which shakes the couch, and my arse, but I'm missing the chest punch stuff. I'm not sure if it's just the scenes I'm testing with because those may just have ultra low bass. I'm been setting up for a few hours, moving the sub from the corner b/c it sounded localized there, to the back of the couch, then to the left side of the couch, and then to the front between the l/r speakers. So far, I think it sounds best behind the couch so I have it there. I've been testing the Cloverfield monster scene, WOTW pod scene, Transformers scorpion scene and don't feel the chest punch. I think I read that the chest punch comes from mid bass vs. the low level stuff. Is there a good scene I can test this with? A few recommendations would be great. I do have the Reference HT files which has the bass, animations, surround sound, visual, and music scenes from movies and concerts so if there are a few here, that would be great. I think the Finding Nemo Darla tapping on the tank is one, but I don't have that disc on me.
