I ended up using YPAO, and playing around with the gain until I got it to set at -5.0. That was about a little north of 9 o'clock. It turned out that was a little less bass for my liking, so I adjusted the gain back up to a little before 12, keeping the receiver settings as per YPAO.
Strangely, YPAO set my front speakers to large with crossover set at 40 Hz., even though a sub was present. I have a 2.1 system at the moment. I had to switch my speakers back to small and my crossover back up to 90 Hz.
