Sub Mini - how do you know it is actually performing as it should?

Hello

My topic title might sound stupid, but I have never had a sub woofer before, so don’t really know what to expect.

I just bought a Beam Gen 2 and Mini Sub.

Connected the Beam to TV and I CAN hear the difference compared to only the TV speakers.

The Sub Mini arrived a few days later, positioned it 2 metres to the right of the Beam/TV. I think I have set up the Mini Sub correctly, white light is on.

Put on some heavy metal music from You Tube…….and I don’t think there is any difference!! 😕  

 

Question - is there a way to flick the Mini Sub on and off while listening to music, so I can see if there is a difference??

Any other suggestions to ‘test’ the Sub Mini?

    If, after that, you still think it’s not working, contact Sonos support who have many diagnostics utilities they can use to check things for you.

      Yes. In the app there’s an on/off toggle under settings for the room. 
       

      Also, plug the Sub into a power extension cable and try it in different locations around the room (the extension cable saves you unplugging/plugging in and rebooting). Position of a Sub and the room’s acoustic characteristics can make a big difference. 
       

      Try streaming something from Spotify or Amazon for a higher bandwidth data source. 

       

      Can someone point me to a thread/sub forum where I can start to learn a bit about the quality of audio sources? (Had a quick look around the forum, but too much info! )

      So much nonsense out there. Pretty much CD quality is as good as you can hear, anything beyond that is inaudible.

      Lossy formats like MP3 are more complicated and not recommended for quality sound.

      Try grok.com and 

      Tell me about digital audio formats
