I'm scratching my head right now. Since getting my 3010 six weeks ago, the sub has never sounded right. My sub is capable of 15-16Hz, but since having the 3010 it just seemed lacking in that department. Also, when I first ran YPAO, my mains, center, and front right presence were detected as out of phase. I checked all the cables and they were right, but I changed the polarity on the speakers anyway assuming that the 3010 was accounting for relative phase. However, it didn't sound right so I changed it back and the tight bass returned.
For the sub, I ran the unit with YPAO and without it using manual adjustment with my SPL in "Through" mode. "Through" did sound better with my sub, but it was still lacking. I also tried the advice from Venemous by disconnecting the sub and running YPAO, then manually tweaking after. Still, it didn't sound right. Thanks nevertheless, Venemous
Although YPAO didn't detect a phase problem with the sub, yesterday I reversed the phase anyway after remembering the experience with the reported out-of-phase on my mains. I changed the sub phase in the 3010 settings and BAM, the walls started shaking and I was almost thrown from my couch. The Incredible Hulk
has never sounded so incredible destroying those helicopters and sonic-blasting-jeeps.
Yamaha, why you not want me have bass? edit:
I also wanted to note that after changing the phase I had to remove my manual settings and actually had to reduce the 49Hz frequency by -.5 in the PEQ, everything else set flat.
