I had read this being a problem with the playbar but I am also experiencing a pulsing effect on just the play 3s while isolated from the playbar and sub. At loud volume playing more aggressive style music the bass drum hits will pull the rest of the mix down to create a constant up and down effect. It’s absolutely awful. When I have playbar and sub playing together it’s not as noticeable. These two speakers should be able to handle loud rock without cutting out. I have tru tuned, countlessly adjusted EQ and nothing works. What should I do?
