@schubert Well, I guess if you consider a Jim Thiel-designed speaker to be an extremely accurate transducer of an input signal, then they should be fine with any kind of music, with consideration given to a particular model's frequency limitation.
I chose Thiels decades ago, without knowing any of the technical aspects of the speakers, at the time. They were the most convincing with recorded acoustic instruments. e.g. guitars, violins, and piano. They just sounded "right", where everything else was "not quite right".
