Subwoofer cutting in and out and crackling

I have the Polk Audio MagniFi sound bar and subwoofer and have a problem with my subwoofer cutting in and out and making crackling noises.

Has anyone else had issues with this?

    Welcome to Polk's forum. In many instances that kind of problem can be caused by interference from a network router nearby. As a test, try unplugging the router and see if the sub works correctly.

  • I had exactly that problem. A brand new Polk system and the subwoofer kept cutting in and out randomly. It was located right next to my router and network switch, so I moved the sub and it cleared the problem right up!

    Is the sub wireless? If not then it has a poor design if network RFI affects it.
