Today I decided to balance the rear speakers again. See my pic on previous page to see why.
They sounded good, but I still felt like the rear balance was off.
Got the idea to connect the rear speakers to the front inputs, that way I could play some music and balance to the center seating position. The new banana connections behind the tv made it a snap to do this.
+2 to left, -2.5 to right
I also pointed the tweeters differently to center the soundstage.
Worked great!
Spiderman Far From Home, around 1:15 has some of the best full surround scenes to test this out.
