Helix P 3M Pair of 7.5 cm midrange with grilles included in the package

The P 3M cone midrange driver is the perfect complement for every fully active 2-way speaker system. The lightweight fiberglass composite paper cone ensures excellent impulse response and minimal sound discoloration, while the highly efficient neodymium magnet system provides linear guidance and minimal distortion.

Furthermore, the basket optimized for flow not only prevents rear reflections, but also guarantees compression-free sound reproduction thanks to optimal voice coil cooling. The P 3M develops its full tonal potential in a sealed and damped enclosure.
