Sensitivity is rated at 85.7 dB (2.83V/1m), while the DC resistance (Re) is 3.6 ohms and voice coil inductance (Le) is 0.99 mH. The subwoofer requires a cutout diameter of 185 mm and has a mounting depth of 126 mm, with six fixing holes for secure installation. This combination of advanced materials and precise engineering ensures controlled, distortion-free bass that will elevate any serious audio system.
