If your reference to "Yamaha" in your list of settings means that you used its auto-calibration, then the sub level should be the same as it was before if you had used the Yamaha before to set levels.
Hi John!
I calibrated my system using an analog Radio Shack SPL meter and a tripod.
I used the test tone from my Yamaha receiver and then adjusted the individual speaker levels +/- decibels via the Yamaha menu so that all speakers had matching levels on SPL meter (75db).
I ran the calibration with the new sub amp and I had to bump the sub speaker level via Yamaha menu from -7db to +3db to get the same output as old amp.
