The palladium system are built and design as 3 way system. I do own p37f and p39f.i do own In the past the rf83. It is wide sound stage and great dinamics,extremely poweful bass, the only issue is has the first generation of loud horns which trends to fatigue your ears in long runs of audio, somehting solved in the reference premier and palladium system.
The rf83 are 2 way system. So definetly it is not a perfect blend using both system.
The right match is the RC64 II or III.
