The frequency response range of 100Hz-12.5KHz ensures that every beat is reproduced accurately.\u003c\/p\u003e\n\u003cp\u003eWhat sets the 8PRO400MR-4 apart is its demodulating rings made of copper. These rings play a crucial role in substantially reducing harmonic and intermodulation distortion associated with voice coil displacement. They also minimize the modulation of magnetic flux during the movement of the voice coil, ensuring a more linear variation of system inductances as input current varies. This results in a cleaner sound output, providing an enhanced audio experience.\u003c\/p\u003e\n\u003cp\u003eThe curvilinear cone shape enhances overall dispersion while maintaining optimal performance.
