Music does tend to be easier to tell XO differences. In my room, bass gets tubby sounding over 90hz. I’ll test with music first. Then find a movie with lots of midbass like a good car chase.(yes tron legacy is a good choice) That should use all the bed layer speakers giving you an idea of what is different. A favorite of mine is Ready player one. Has everything. Also, Hacksaw Ridge. Great Atmos track, and there’s guns and explosions in every speaker. Oh, another favorite is Lone Survivor. Every gun has a unique tone, and the track uses all speakers and should help ID different settings. I usually put it in for a demo and watch the whole damn thing. Lol. Sooooo many choices...
