Still having trouble understanding your writing, punctuation might help. So avr trim level was set to -10 for every speaker as well as the sub? That's odd. Does your version of Audyssey ask you to set gain on the sub to aim at 75dB test tone before starting Audyssey? Not unusual for many to boost the sub level a few dB after running Audyssey, tho and of course you can change any of the levels to what you like. What you expect at various levels is hard to know. Have you tried measuring results, even with a phone app if you don't have a measurement mic?
