About the prophecy9
The PMC prophecy9 is a state-of-the-art 3-way floorstanding loudspeaker that sets a new benchmark in hi-fi performance. It delivers an expansive soundstage, precise dynamics, and immersive musical enjoyment from a slim, room-friendly cabinet. Key technologies include PMC's Advanced Transmission Line (ATL) with 2.57m effective length for deep, nuanced bass, and LaminairX aerodynamic airflow for clean low-frequency extension without chuffing. The drivers feature a precision 1"/27mm soft dome tweeter and 55mm/2" soft dome midrange housed in a profiled baffle with proprietary waveguides for spacious highs and tangible vocals, paired with two 5"/125mm long-throw mineral-filled polypropylene bass drivers. It pairs well with modest amplification (30-300W recommended) and scales with higher-end systems. Sleek design includes full magnetic grilles and finishes like Mediterranean oak, natural walnut, or blackened walnut.
