Pearl 20/20 Graphene

About the Pearl 20/20 Graphene

The Joseph Audio Pearl 20/20 Graphene loudspeaker is a 3-way floorstanding speaker composed of two modular sections: the lower half houses twin 8" aluminum cone woofers with surround damping, four-layer voice coils, and double-magnet systems for powerful, controlled bass; the upper module contains a 7" graphene-coated magnesium midrange driver and a 1" Sonatex dome tweeter. The graphene midrange driver incorporates copper pole pieces and rings, optimized via Finite Element Analysis for improved power handling and low distortion. The tweeter offers wide dispersion, accurate phase response, and a flat frequency response for fatigue-free listening. The speaker employs Joseph Audio's patented Asymmetrical Infinite Slope crossover technology with extremely steep 120dB/octave slopes to minimize driver interaction and distortion, using military-grade polypropylene capacitors, resistors, and high-current inductors. This design yields excellent imaging, power handling, and frequency response with a smooth, even sound across a broad listening window. The Pearl 20/20 Graphene delivers a dynamic, detailed, and natural musical experience with authoritative bass and stress-free clarity, suitable for a wide range of music genres.
