describe

The subwoofer employs a high-power subwoofer driver, with a high-Q resonance chamber designed as a front-and-rear ported enclosure to control the amplitude of the driver at its resonance frequency,

effectively suppressing higher-order harmonic distortion. It delivers deep bass extension and high sound pressure levels, resulting in a clean sound and reduced system distortion during high-dynamic-range playback. Additionally, the use of dual-voice-coil differential drive technology and a high-peak-to-peak offset design enables the reproduction of true, flawless sub-bass sound. A large ring-shaped heat dissipation design significantly enhances cooling efficiency, ensuring the driver unit operates at a low temperature, which greatly improves power handling and reduces harmonic distortion, delivering a clean, deep, and powerful low-frequency sound.
