As I understand it, you place a Cylindrical Radiator speaker, combined with one or two optional Bass modules, close to the musician, and it takes care of ALL amplification, that is,
on-stage monitor for the musician
on-stage monitor for his/her fellow musicians
and PA for the entire venue.That last one is amazing, no need for separate amps + speakers for the audience. I would think that in order to cater for the audience, the sound would have to be so loud it would bother the musician, but apparently this is not the case. It’s not the first time Bose Research has done amazing stuff.
