TENORA’s body housing shares the same design as the MIROAK-II JAPAN Limited model, but with a material change: instead of ABS resin, PLA resin is used. PLA is harder than ABS, but it has lower rigidity. In practical terms, this means it is less prone to deformation.
Since the TENORA’s driver material is not as rigid as that of the MIROAK-II, overly soft materials at the rear of the driver could result in excessive mid-to-low frequency volume, compromising the clarity and definition of the mid-to-high frequencies. To address this, PLA resin, which is both resistant to deformation and easier to mold, was chosen for the rear body. To reinforce the structure, a stainless steel ring is used to secure the rear body’s backplate.
