Persona is Paradigm's all-out top-of-the-line premium speakers. Persona uses Truextent® Pure Beryllium that is specially formulated to be exponentially stiffer and significantly lighter than other premium diaphragm materials. It enables superior transient response and virtual transparency, with vanishingly low audible coloration. This is immediately noticeable in lifelike sound, incredible imaging, depth, dimensionality and clarity. This great sound is apparent throughout the listening room.
