Just set up an Era 300 wall mounted using the Sonos Era 300 bracket inverted. The sound is just flat the EQ setting make no difference to the sound at all. Loudness on or off there’s no difference in bass, treble + or - bass + or - doesn’t change the sound level? Not impressed just upgrade from a play 5 Gen 1 and the quality of sound was so much better from a 8 year old speaker! Is there something set up wise I’ve done wrong?

Thanks in advance.
