High performance in a super flat design

The DBA 201 F flat active subwoofer enclosure optimized with FEM simulation ensures superior performance, maximizing the subwoofer output with a super flat size. 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 F 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 F 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 F 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 F 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 F is fully EV (Electrical Vehicle) friendly.

 

The DBA 201 F flat active subwoofer enclosure optimized with FEM simulation ensures superior performance, maximizing the subwoofer output with a super flat size. The massive magnet of the 8 in. driver provides optimal control during the highest cone excursion.

 

The DBA 201 F 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.
