I have had a Sonos one for around two weeks.  At 25% volume I can hear beautiful low bass tones vibrating my hardwood floors.  When I increase the volume to 50%, the bass all but disappears into the music.  I have read in another post that this is the result of the loudness feature enhancing bass at low volume level.  When I toggle off the loudness feature it reduces the overall richness of the sound and still loses bass with increased volume.  If this is an automatic protection feature to keep the bass from distorting, I would prefer control that myself.  Would it be possible to provide a software solution that would allow this speaker to deliver consistent tones at all reasonable volume levels.   Thanks in advance!
