Joseph Audio Pearl Graphene Speakers
Because Every Note Matters
Experience music’s very heart, as dynamic nuances and subtle details come to life with the finesse of a master’s touch. Powerful low frequencies are delivered with commanding control, transporting you to a world of music that feels effortless, natural, and vibrant.
Joseph Audio’s Pearl Graphene loudspeaker, a masterpiece in pure musical revelation, has an almost magical ability to disappear, making it the perfect choice for music lovers who want to escape the upgrade cycle and fall in love with their music for life.
Designed with separate enclosures and connected by solid brass points, the Pearl’s tweeter and midrange are isolated from the dual woofers below. The patented Cardas vise-type input posts (CE approved) ensure maximum contact, while custom aluminum cone woofers with additional magnet mass and copper pole pieces provide the cleanest bass reproduction possible. The zinc alloy cast frame offers extreme rigidity and narrow fingers to minimize internal reflections.
A field array of tiny, powerful magnets surrounds the tweeter’s voice coil, keeping the area behind the dome free of reflective materials. Listening to Pearl Graphene speakers allows you to rediscover your favorite music, free from the usual artifacts that cloud the sound and create artificiality in sound reproduction.
Transform your listening time, and experience the nuances and magic of live performances that lesser systems often miss.

“With every kind of music, the Pearls allowed the music to speak most effectively.”
— John Atkinson, Stereophile
“Music may be art and audio may be engineering, but sometimes, if we’re very lucky, the combination can be magic. Go hear the Pearls; we suspect magic happens around them a lot.”
— Wes Phillips, Stereophile
Sensitivity:
86 dB SPL, with 2.83 volts RMS @ 1 meter, 4 pi (anechoic).
Sensitivity combined with impedance indicates how much amplifier power is required for the loudspeaker to play at satisfying volume levels. When comparing this spec to low impedance (4 ohm) designs, you must add 3 dB to the figure, since 4 ohm loads draw twice the current from the amplifier, providing the illusion of greater sensitivity, while placing more stress on the amplifier’s power supply. The moderate sensitivity of the Pearl indicates that even smaller amplifiers can achieve realistic levels in all but the largest rooms.
Impedance:
System impedance indicates whether the speaker presents a “hard” or “easy” load on the amplifier. True 8 ohm speakers are less amplifier and cable sensitive, and partner well with a broader range of amplifiers, including tube designs.
Crossovers:
3-way Series/Parallel Asymmetrical Infinite Slope Crossover at 2 kHz & 130Hz.
Constructed of specially selected components, Each individual network is precisely adjusted, resulting in a virtually perfect match to the original prototype.
The steep filter slopes ensure good acoustical behavior in the crossover regions, with a minimum of acoustical interference, along with low distortion and wide dynamic range. Driver acoustic responses are in-phase throughout the crossover regions.
Frequency Response:
The Perspective delivers a very smooth and even response over a very broad listening window. Unlike conventional low order crossover designs, the speaker retains its sonic balance over a wide angle both vertically and horizontally. This results in a higher level of fidelity than a simple on axis measurement can reveal.
Listening window response:
within 2dB from 25 Hz to 20 kHz.
