  • Low-resonance basket made of glass fiber reinforced plastic with optimized voice coil ventilation for high load capacity
  • Grid included
SKU: P821300 Category: Tag:


The P 3M is the perfect complement to any fully active 2-way speaker system. Its lightweight fiberglass-paper-compound membrane ensures excellent impulse response and maximum discolouration, while the efficient neodymium magnet system ensures low-distortion drive. The flow-optimized basket not only prevents rear reflections, but also ensures compression-free playback thanks to optimum voice coil ventilation. The P 3M unfolds its full tonal potential in a closed and damped cabinet.
