The newly developed 6.5-inch mid-bass driver features a Multi-Wall carbon fiber cone with a layer of XG Nanographene, providing optimal stiffness to weight ratio and an ideal damping factor. The driver frame has been designed, simulated, and tested for the optimal combination of stiffness and damping. The minimum acoustical impact is achieved by reducing vibration modes while maximizing airflow. The motor system incorporates extra-large magnets to ensure a stabilized magnetic field in the 39- mm pure titanium voice coil. The A1 mid-bass driver is optimized for minimal music-related distortions in its bandpass, in both the frequency and time domains using state-of-the-art finite element analysis simulation of acoustical, mechanical, electromagnetic, and thermal behavior.
