I came across what may be a reasonable explanation for the possible effect of Acoustic System Resonators - it seems that this kind of devive may produce multiple harmonic overtones at the same time. Similar to what happens if a tube amp is overdriven but different becuase it does not necessarily add richness to a the note played...in fact it is multiphonic and polyphonic (adds many notes - quite different from a bell).
Of course, this is passive - so it may only respond to excitation by the sound waves in the room, however, given our huge hearing sensitivity (0 to 120 db spl) and the fact that a subtle sound from a ringing cup may be audible between loud notes when music is briefly quiet then it may add something.
What will it add....if you read my link above then you will get an idea...this type of thing is used in meditations by monks...so atmospheric kind of shimmering quality is to be expected.
Is this audio reproduction - no, not in my mind but it may have an audible effect and that effect may be pleasing to some people. YMMV
