High performance in a compact stylish design
The DBA 201 double passive radiator enclosure made with solid MDF and optimized with FEM simulation ensures superior performance, maximizing the subwoofer output. The massive magnet of the 8-in. driver provides optimal control during the highest cone excursion.
Extra full set of controls to fine-tune the in-car performance
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.
Auto turn-on and standby mode
The built-in audio sense circuit allows the DBA 201 to turn on and timeout to standby mode automatically. You can switch off the audio sense function when a remote turn-on wire is available.

Technologies
The 440 W Class-D amplifier provides an unmatched performance/size ratio, drawing less current from the vehicle’s electrical system. He-Li technology (high efficiency/low impedance) is optimized for the 0.4 Ω load of the DBA 201 subwoofer driver, and the sealed enclosure.
DBA 201 can handle speaker-level signals up to 30 volts (1.2V – 30 V rms) and includes USS for OEM systems and handles RCA line-level signals as well (0.2mV – 5 V rms) from aftermarket systems. Thanks to the low idling current and wide operating supply voltage (6.5V – 18V) DBA 201 is fully EV (Electrical Vehicle) friendly.
The DBA 201 double passive radiator enclosure made with solid MDF and optimized with FEM simulation ensures superior performance, maximizing the subwoofer output.
The DBA 201 is designed to easily release via a Plug & Play Molex® and harness, which includes the power connection. When you need extra cargo room, you can quickly unplug and remove the box.
