Short preface: Every time I had any changes in speakers configuration I made quick (3 positions) Audyssey auto-calibration, but was never impressed by results - neither speakers distances were calibrated correctly, neither It fixed my sound issues - mainly problems hearing people's voices.
During my [strike]trolling[/strike]
exploration here on forums I found this
great and very detailed guide on correct Audyssey calibration.
Last weekend, while my better half was at work I tried to follow the guide to the letter and used all 8 position measuring calibration provided by my MultiEQ XT on Onkyo TX-SR805.
Whole calibration process took at-least 30mins, but the results are nothing short of amazing - now the voices come out crystal clear and surrounds now actually blend very nicely and even wife noticed big difference...
Is it placebo effect, possibly
But I had issue with not-clear people voices since forever and many other HT owners I know suffer from same issue...
p.s: To position mic at ear levels I used camera tripod
