- 4″ high temperature, dual layer, Inside/Outside voice coil for higher efficiency, preventing performance loss through thermal compression
- Triangulated coil reinforcement increases stiffness with no additional moving mass, thereby increasing sensitivity, while maintaining a long Xmax
- Finite element analysis optimised magnet assembly delivers remarkably low harmonic distortion and very high motor strength
- Smart chassis design minimises reflections back onto the cone, significantly reducing acoustic distortion
- Intelligent heat management in both chassis and magnet assembly design offers increased output level
