A maximum linear excursion (Xmax) of 4 mm ensures clean, distortion-free bass even at higher volumes, while the 1.1 mH voice coil inductance contributes to smooth frequency response. The woofer features a nominal diameter of 254 mm, a mounting cut-out diameter of 232 mm, and a depth of 111 mm, with four mounting holes for secure installation. The DC resistance measures 3.75 ohms, making it compatible with a wide range of amplifiers.
