The Sony XBA-Z5 adopts the latest 16mm aluminum plated LCP dynamic coil unit, and the aluminum plated LCP diaphragm is a diaphragm with high response capability. The diaphragm composed of thin film aluminum coated LCP has high response capability, reducing sound rendering and presenting clear mid and low tones. The number of folds has been increased on the diaphragm, making it more compatible with deformation and reducing distortion. At the same time, a linear drive moving iron unit is also adopted, which is a T-shaped symmetrical armature and uses a direct drive structure. Replacing the traditional U-shaped armature with a T-shaped symmetrical armature can enhance the vertical symmetry of vibration and highly restore the original appearance of the sound source.
