My dad just finished construction and installation of a new TV viewing room.
It has pretty bad acoustics with much echo.
Walls are drywall, vaulted ceiling is drywall, floor is refinished maple. Not so many soft surfaces.
We have a full 7.2 setup consisting of:
Yamaha NS-IW960 (3) for front in-walls
Yamaha NS-IW660 (4) for side surround and rear surrounds also (in-walls)
Yamaha YST-SW315 (2) Subwoofers
I've ran YPAO many times and believe I've tweaked it as far as i can without manually changing the RX-A2020's equalizer.
I believe we need to add some sound absorbing panels to reduce echo and help stop the "highs" from bouncing all over.
When listening to music, there seems to be a lack of mids and the highs are piercing, especially out of the YPAO calibrated sweet spots.
Please find some pictures attached.
Any suggestions welcome. My first thought is to add some sound absorbing tiles above and slightly below the air vent you'll see in the pictures. I think i should also ad as many as i can on the rear wall...
But if there is some RX-A2020 setting I missed, I'd love to hear about that too
