P 3M
The P 3M cone midrange speaker is the perfect complement for every fully active driven 2-way speaker system. Its lightweight glassfiber-paper compound cone guarantees excellent impulse response and minimum sound discoloration, whereas the highly efficient neodymium magnet system provides for a linear drive and minimum distortion. Additionally, the flow-optimized basket not only prevents rear reflections, but also ensures compression-free sound reproduction thanks to optimum voice coil cooling. The P 3M develops its full tonal potential in a sealed, dampened enclosure.
