Dual-Dynamic Hybrid

Two dynamic drivers for weight. One BA for edge and clarity.

Forteza combines two 10 mm dynamic drivers with one balanced armature in a three-way system. The design is intentionally full and energetic, using the dynamic drivers for low-frequency scale and the BA for upper-range definition.
