Hi, I have a  compact sub woofer and never really used as don’t feel the sound quality is great so I’m thinking is it actually not set up properly or is it the actual woofer. I have followed the procedure to set up and have paired it , constant red light shows on the bar and the sub woofer but sound from woofer is really muffled, not clear at all .? Any help would be appreciated
