It just looks to me like the subs are set to a higher level than the mains.
The first set of measurements were run without Audyssey. (Didn't post those pics.) I wasn't sure how to disable Audyssey from my previous use but I thought I did by enabling the equalizer in the Onkyo. I didn't adjust any levels on the EQ. I just wasn't sure how to turn off Audyssey otherwise. And believe me, I looked.
When I did it this way, I used an SPL meter to set the subs and the left speaker so that they were both at 75db's. Here is an FR graph it did in the beginning with Audyssey off (I think) and subs at 75db's and left speaker at 75db's.
So it's not confusing…I ran a set of measurements without Audyssey first, calibrating the subs volume and the left speakers volume to 75db's with an SPL meter.
The graphs had the elevated bass.
So I ran another set of FR graphs with the subs in their various positions again but this time with Audyssey calibrations before each positioning. Before each Audyssey calibration, you are prompted to set the subs to 75db's, which I did.
The problem there could be that DEQ is the default and it was on. But I still had the bloated bass in the first set of non-Audyssey measurements.
Tomorrow I'm traveling for Thanksgiving and won't be back and able to measure again till late next week. I'll look into whether or not DEQ is on and if so, turn it off. I'll double check levels of subs and speakers after Audyssey runs to make sure the subs aren't running hot for some reason. And if the graphs still come in with the elevated bass, I'll manually turn the subs down, remeasure and see what happens. I'll repost here with results.
orange looks to be the best placement, as for your eq/levels, that's another story [/quoteWhat's strange is that 3 of the six measurements are with only one sub placed and on. The other three are duals with volume knobs between 8 and 9 o'clock.. In both cases, Audyssey asks that the sub level be set to 75, which I confirm on the on screen meter and my Rat Shack meter. If I turn down the subs volume knob any more it will be almost at the minimum.
Perhaps the issue is indeed Audyssey's DEQ being on.
What is the right way to turn off Audyssey on the Onlyo. It's two years old, a 705 or 706 with Multi EQ. The manual doesn't say.

Just saying. Word. Never post online you're traveling. Too many eyes looking for these types of comments.
