Try the attached ady. There's something odd about your measurements, group delay cuts off at 5kHz for all speakers hence I am not sure if the subwoofer distance was correctly aligned. Also sub volume might need -10dB adjustment.
Magic! It loaded up without any problems and sounded pretty good! I did a quick (ears only) comparison with my favorite calibration and it sounds better in the bass department while not impacting the rest of the frequencies - even in Reference mode. With the default Audyssey calibration, I was finding that the Ref mode was messing up my front speakers' default response too much so I was listening to them in LR Bypass mode. With this new calibration, I can listen in Reference mode without any issues and the bass is tighter as well. I played music at +2 for the sub - for movies I usually reduce the sub to -6 or -7 (this allows me to increase the master volume to reference levels for dialog clarity and gives me a little punch in loud crashes and bullet scenes)
This is a great calibration! I can use it at Ref for both music and movies. I will do some REW measurements in the evening with this calibration to see what I am listening to.
Thank you so very much!!
That looks pretty good - the key, of course, is how does it sound? There does seem to be a room mode at about 60Hz, - these are pretty intractable and can be dealt with somewhat.
It sounds good as well. I listen to music and it gives me very good imaging. To the point that I prefer Stereo mode over (Apple) Dolby Atmos. I was playing an album last night and it wasn't clicking so I checked, and Apple TV had picked up the Dolby Atmos version. I turned DA off to get the regular Stereo version and the sound stage improved dramatically. It could be because of the weaker 685 bookshelf speakers in the back or the (Marantz) AVR performing poorer when driving all 5 channels. But this set up sounds absolutely stunning in 2.1 channel stereo. The room *lights up* with music!
The only issue I have is that the bass causes some rattle. I tried running REW frequency generator at 75dB. I started with 80Hz and went lower till 20Hz. I got shelves rattling at 72Hz. I could walk up to them and lock them in place. Then I got a picture frame rattling at 45 or so and another one at 30. I fixed one and removed the other. I still get an occasional vibration here and there, but overall it is pretty good!
Thanks for sharing the tip on Roon. I will look into it.
