One more note. My room is like 30ft x 31ft, with the HT area over in one corner area. Last night I ran the receiver test tones manually, so I could cycle through each speaker one by one at my own pace. When I got to the sub, I adjusted it at 75dB's also from the main location seat. Now the needle will fluctuate a little, but if you keep it on Slow and C-weighting to pick up the low freq's, you'll be fine.
Then out of curiosity, I walked around the room and watched the meter to see how it would act in different locations. For the most part it stayed pretty true in the 75dB's area. I was amazed that when I walked over to the opposite corners, even the farthest corner over by the bar area, it was dead nutz on 75dB's. I thought that was pretty cool.
