I installed a sub mini with 2 era 100s. I can’t hear any difference with the sub on or off. I called tech support, they were very polite but and they said everything is connected correctly and working correctly. I have used sub woofers for decades. They sound great…I can’t believe Sonos would put out a product that you can’t tell a difference whether it’s on or not. I think there’s something wrong.
When the unit initially booted you could hear the sound very distinctly. I have tried multiple musics types and no difference.
Any suggestions??
