DBA 201 SUB BOX
200 (8) mm (in.) | 440 W | 0.4 Ohm | Active subwoofer box with double passive radiators
High performance in a compact stylish design
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.
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.
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 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.
The DBA 201 double passive radiator enclosure made with solid MDF and optimized with FEM simulation ensures superior performance, maximizing the subwoofer output.

FAQs
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
