The HX 300 D car audio subwoofers were designed to reproduce the very lowest octaves of the audio spectrum with precision, impact and power. Groundbreaking technologies in every detail: V-cone, forced ventilation system, low-resonance basket and ultra-efficient motor assembly. The Hi-Energy subwoofer range features dual coil models to increase the flexibility of your subwoofer system design.
This will allow you to manage the different connectivity solutions and the number of subwoofers in a particular design in order to make the most of the amplifier power delivery characteristics. Dual voice coil, i.e.: double the power, double the efficiency, with even smaller boxes. The best solution to all your needs; low-frequency output and control that will meet your most enthusiastic expectations.
