I recently purchased a sonos beam shadow edition from ebay in brand new condition. I set it up the other day and the sound quality was very underwhelming. Then with hope, I added a sub gen 3 to the setup and something weird happened. I saw that although the sub was added there was no output. Then I played with the sub on/off toggle switch and there was weak output from the sub with the toggle switch off and no output from sub when the toggle switch is on position.
I can easily compare the sub output and normal on/off position with a sonos arc I currently have.
Does anybody have any idea/recommendation or a similar incident. I would appreciate any help
Thanks and Regards
