My 2nd UMIK1 arrived yesterday so hopefully tomorrow I'll get to play some more.

I had a chance to run some measurements with the new mic. Will try and post them tomorrow.

I was a busy boy last week emptying 5 gallons of paint on the mainfloor, basement stairwell, and basement. I started a week past Sunday and completed everything by this past Friday. No more looking at scuff marks or patched drywall. My ottomon came in today. I should have ordered black but this is close enough. At least now, the middle seat has a place to rest their feet and I can hide the blankets.

What you said is all correct.
Added to that is the measurements must be taken with an acoustic timing reference.



The question I intended was IF you could route a signal to one of those speakers ONLY if you wanted to. On a windows machine a HDMI connection and soundcard driver such as ASIO4ALL are needed.



Definitely a process of changing settings and re-measuring can be used to see if a better result can be achieved.
Somewhat recently, REW added added the Alignment Tool feature. Now instead instead multiple measurements taken to find the best result, just the 3 mentioned for this exercise and the alignment tool will calculate and show the rest.
Here's an example:

You may or may not find that YPAO has set the delays (distances) and levels optimally.

Taking the same 3 measurements with a different XO may or may not show a XO other than 80Hz to work better (for you).

A journey like this is all up to you of course and if taken you may find you have a preference for something other than the best looking SPL chart and if that's the case go with your ears.
Its a good thing I'm still off on disability as my reading comprehension is still affected 5 months after my wife's passing.

I was able to run Left Main only and Right Main only measurements and these measurements were run with acoustic timing reference selected by default. The measurements are below.
Left_Only.jpg
Right_Only.jpg

Now for sub only.. The sub was connected via Sub out on the AVR..mains set to small, and Xover set to 200 Hz. Again the measurement was taken with acoustic timing reference selected by default.

In fact all my measurements that I ever posted were taken with acoustic timing reference selected by default. Is this correct or should I run a set of measurements using "no timing measurement"

I decided to run a few more full frequency sweeps with YPAO set to flat and changing the xovers to 40,60,80,90,100,110. Also, I ran the measurements using "no timing measurement" . I still think setting the xover gave me the best result. Again, 3 measurements were taken across the couch for each xover setting,

Xover=40
Flat@40.jpg

Xover=60
Flat@60.jpg

Xover=80
Flat@80.jpg

Xover=90
Flat@90.jpg

Xover=100
Flat@100.jpg

Xover=110
Flat@110.jpg

The last graph is YPAO is off and the Xover is set to 90 Hz.

It’s a little difficult to see on these graphs for me, but does it look to you like theres a trend of the SPL being lower at the XO frequency than that same frequency is on each graph before it and after it? Or put another way, is the SPL tending to dip at each XO setting?

If yes then the distance setting for the sub may not be optimal. If you’d like this can be checked with the following measurements and the REW file posted.

Make sure any DSP processing is off. On the Yamaha I believe this is “Direct” mode.
Place the mic at the MLP which should be equidistant from each main speaker, but may not be.
Set the XO to 80
Measurements must be with a timing reference and the same speaker used as timing reference for each measurement.
20Hz to 400Hz range for each measurement is good.
The mic can’t move between measurements.

Front Left with No Sub
Front Right with No Sub
Sub Only with signal to Front Right/Left channels simultaneously and Not the LFE channel.

If you can’t do the sub measurement with a signal sent to both main channels then choose either one. It will only affect SPL and that can be adjusted to suit after.

Did you see the graphs on post 39 for the left/right main only? I did have YPAO Flat turned on.

Reposting using 1/6 smoothing at 80 Hz,

I retook measurements across the listener position making sure the head of the mic extended at least a couple of inches higher than the back of the chair. The results look much better....
