About: Hertz DBA201 8" 220W RMS Active Subwoofer Box

The DBA 201 active subwoofer box features a double passive radiator enclosure made with solid MDF and optimized with FEM simulation to ensure superior performance, maximizing the subwoofer output. The massive magnet of the 8-in. driver provides optimal control during the highest cone excursion.The built-in 24 dB/Oct. low-pass crossover filter with a variable cutting corner frequency (50÷150 Hz) allows you to perfectly match the DBA 201 to your speaker system. Adjustable bass boost (0÷6 dB @ 45Hz) can add bass output as you prefer, allowing correction for OEM sound equalization. With the phase inverter (0-180°), you can optimize phase alignment between the DBA 201 and your speaker system, regardless of the subwoofer’s position in the car. The subsonic filter (15 Hz @ 24 dB/Oct) protects the cone from over-excursion and amplifiers from overheating. The input sensitivity control is the perfect tool to maximize the overall system output level while preventing clipping.
