Pearl Graphene Ultra

About the Pearl Graphene Ultra

Celebrating 25 years of the Pearl series, the Joseph Audio Pearl Graphene Ultra represents the pinnacle of the Pearl line with extensive refinements. It features a redesigned subwoofer system with newly developed graphene-coated magnesium woofers in each bass cabinet, providing superior bass precision and extension. The tweeter and midrange are housed in separate enclosures isolated from the dual woofers, linked by solid brass points to reduce interference. The input posts use patented Cardas vise-type design for maximum contact. The woofers have zinc alloy cast frames with extreme rigidity and copper pole pieces for clean bass reproduction. The tweeter employs a field array of magnets around the voice coil to keep the dome area free of reflective materials, enhancing clarity. The crossover components are carefully selected and optimized for musicality, employing Joseph Audio's patented Asymmetrical Infinite Slope crossover technology for steep slopes and minimal driver interaction. The speaker delivers a smooth frequency response from 25 Hz to 20 kHz within 2 dB, with a sensitivity of 86 dB and nominal impedance of 8 ohms. Dimensions are approximately 43" H x 11" W x 18" D, with a shipping weight around 330 lbs. The Pearl Graphene Ultra is designed to provide a compelling, natural, and immersive listening experience, regarded as the best sounding speaker in Joseph Audio's history.
