As you can see, the pink noise level is essentially exactly the same, which contradicts the claim in the Audyssey thread. Of course, this is only one data point, and if anyone questions this conclusion, I encourage them to run the test themselves and post the results.
We are still looking forward to HD's test results, hopefully sometime this weekend.
Aww hellz. Here we go:
Audyssey 4th run (post AVR processor reset)
adjusted Mackies to 0dB gain and Audyssey came up with trims of:
After Audyssey, AUD ON AVR test tones register in REW SPL as:
After Audyssey, AUD OFF AVR test tones register in REW SPL as:
I erroneously remembered them being around 64dB a few runs back, but checking my notes they were identical. So the microprocessor reset has not changed the results of Audyssey. Interestingly enough, the SPL levels I got on this run were identical to the ones generated previously when I had the Mackies at -10dB gain and Audyssey set the trims in the positive.
Audyssey is clearly limiting my volume output. I knew it seemed like I couldn't make any gains between AVR MV 0 and +15. Here is a log of me running a Pink PN -30dB via REW starting at AVR MV 0.
I placed the cursor where I hit +4 on the AVR. (I guess you'll have to trust me as it doesn't appear I included the cursor!) At this point I no longer heard an increase, and for the remainder you can see there was none, all the way to +15.
Alternatively disabling Audyssey, though having no effect on the AVR's pink noise (as shown earlier) did allow me to run the AVR louder.
I stopped at +8 as I was going to wake our baby and have to face the consequences.
Is there a way to defeat this Audyssey limit? Or should it even be there in the first place?!
OK, so that's issue #1
. On to the actual results. I was able to run a full -12dB FS sweep and still have 4dB of headroom this afternoon at AVR MV 0. Not sure what changed. Anyhow:
Audyssey run but off (so no sub BGC) but with my custom x-over of 120Hz and custom sub distance of 7.5ft
Audyssey ON with BGC but with my custom x-over of 120Hz and custom sub distance of 7.5ft
Audyssey ON with BGC with auto x-over of 70Hz and auto sub distance of 8.5ft
Now I realize that getting a flatter response isn't everything, so here are comparative waterfalls:
My custom x-over and distance
My uninformed opinion is that the custom settings are still superior--would love to get feedback on this.
And I don't really know how to properly read them, but the spectrograms have me believing perhaps I should stick with what Audyssey chose, as my custom settings seem to be making things worse over there...
The saga continues. Thank you for your continued attention.
