If it doesn’t work with R&B then I would re-examine your choice or determine if it was the listening room or something else.
A good speaker should work equally brilliantly with absolutely anything - absolutely anything. A speaker that works with some kinds of music but not others is obviously coloured and or distorting.
The only thing that should differ between recordings or styles of music is how loud it needs to be played to sound its absolute best. Most recordings have a loudness sweet spot that was determined by the engineer and producer. This sweet spot is the volume level where the recording overall sounds best.
