IMO the PEQ was the only thing keeping the 3000 in the house and not having it exchanged for a Denon 4311
Well, just got done running some more tests.. won't post the graph since the curves are pretty much the same as before. However, I have some observations..
I was a bit mystified by why the system measured the same when using ANY of the PEQ settings, including through, which turns the PEQ off..
I copied the settings to manual and examined, and found that YPAO is doing exactly NOTHING to either of my subs.. well, on SUB1 it's applying a -0.5db to freq 78hz.. that's IT ..
It's almost as if YPAO said, well that's pretty close .. might as well leave it alone
I then measured on the second row and the responses aren't anywhere near as flat.. it seems like I have some serious room mode problems on that second row, and YPAO is giving up because fixing that would seriously screw up the good response on the front row.
In summary, it seems I need something more powerful to EQ, and/or perhaps some room treatments to help on that second row.
