My paired Play 5's and sub have a good sound but the small drivers need assistance of tone controls or loudness filter when listening at contrasting volumes. When raising Play 5's volume from around 40/50% to higher, the bass treble boost feels too much, I got the impression that it is either on of off. Navigating multiple menus to manually switch off the loudness filter is awkward.
There have been earlier posts with people stating that it is variable relative to volume.
Approx 6 months before this post, I presented this as a question, to which a Sonos rep stated that loudness is not dynamic, they offered to forward the suggestion of linking loudness and volume to development.
I searched for info on how Sonos crossovers etc work but found very little. Before I get the SPL meter and test tones out, can anyone can provide some juicy links to independent tests which demonstrate any differences at various volumes and filter settings?
