Hey Dan,
That receiver is an American version so I can't download the manual for some reason
. I wouldn't use PEQ measurments established by YPAO @ 160. That why I recommended skip if viable with your receiver.
Hehe..before you make yourself nuts replace that rug/carpet before you proceed with any changes or updates to your system. Like was mentioned eariler your room is the issue because you've created big reflection point by removing the carpet.
BTW...You could try your hand at EQing yourself(ie: GEQ if applicable) but I quickly put that idea to rest after doing some tinkering...
.
