6NPM

The 6NPM is a very high efficiency, (97 dB 1watt / 1 meter in 1l enclosure) 6-inch midrange speaker with incredibly linear frequency response characteristics and ultra low harmonic distortion artifacts. The 6NPM has extremely high sound quality. The 6NPM uses a lightweight paper pulp, specifically developed for this application. This unique cone provides the ideal weight to strength ratio.

Voice Coil
At the core of the 6NPM is it’s voice coil technology featuring edge wounded aluminum ribbon wire. Unique lightweight and very short former provides the ideal transfer of power between the voice coil and the cone assembly and assists in reducing the distortion artifacts. By combining this material with the state of the art adhesives, the 6NPM delivers incredible performance.
The neodymium magnet is in a direct contact with the CNC exposed aluminum section of the basket, hold in place by our thermal transfer adhesives. This design dramatically improves the heat transfer. Further more, based upon a request, we have developed added on aluminum heat-sink. The heat-sink is a recommended optional accessory for applications in sealed mid-range, low volume enclosures.

The 6NPMX8-164 is a 6.5-inch high-efficiency neodymium midrange driver designed for professional sound reinforcement systems requiring high sensitivity (97 dB 1W/1m) and controlled, low-distortion reproduction in the 300-5000 Hz range. It features a lightweight paper pulp cone on a fabric surround, driven by a 1.75-inch edge-wound aluminum voice coil on a glass fiber former. The motor and suspension are optimized to maintain consistent performance at high drive levels, with controlled excursion and reduced thermal compression during long-term operation.

The driver is rated for approximately 180 W AES / 360 W continuous power handling and requires active DSP crossover management. A high-pass filter in the range of 300-500 Hz (24 dB/octave Linkwitz-Riley recommended) should be set according to the chosen enclosure volume and system architecture. The neodymium motor provides direct thermal coupling to the aluminum basket, and an optional bolt-on aluminum heatsink is available for sustained high-power operation in sealed low-volume enclosures where thermal management is critical.

This driver is particularly effective in professional touring line arrays, compact point-source loudspeakers, coaxial monitor systems, and horn-loaded midrange applications, where high sensitivity, low distortion, and compact enclosure requirements are priorities.
