For the midrange cone, given its much less heavy stress than the woofer, we opted for a more classic choice, but more suitable for medium and high frequencies. Like a "paper", but not a classic paper, it is a mix of cellulose pulp nanocrystals used as a binder with the addition of Dolomite spruce fiber, the same type of wood used for the construction of Stradivari violins and called "wood resonant". In addition, a percentage of jute and sisal fiber is added, both of these materials offer compact and very long fibers.

 A surface layer of phenolic resin spread on both sides of the cone to balance it perfectly and increase its rigidity with a negligible increase in weight. Furthermore, this transformation makes the material virtually insensitive to moisture. The cellulose nanocrystals used as a binder have a Young's modulus higher than aluminum and other metals, but with a much higher internal damping. Additionally, its mass is only a small percentage of that of a metal, in short, it is the ideal mix for lightness, stiffness and damping, all for maximum natural reproduction.

 The 10.M midrange uses the same type of basket technology used for the woofer, with a mix of aluminum (Avional) and 

carbon fiber, allowing the speakers to operate with maximum clarity and dynamics. Although expensive to implement, the use of aluminum in our speakers plays a fundamental role in our design philosophy. The 10.M also implements a radial voice coil ventilation system.
