So I guess we are in agreement on this, that he should follow instructions, but in their instruction manual Denon did not tell us to turn the subwoofer off when running Audyssey. Did you make a typo in your post#20 then? Again, you said:
Actually I don't think you can even turn it off in speaker set up but you can set it to "none". As soon as you set it to none, it will set the mains L,R to large.
