High performance in a super flat design Internal 440-watt peak Class D amplifier Compatible with every car audio system Plug & Play connection Extra full set of controls to fine-tune the in-car performance 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 d - B/Oct. low-pass crossover filter with a variable cutting corner frequency (50150 Hz) allows you to perfectly match the DBA 201 F to your speaker system. Adjustable bass boost (06 d - B @ 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 subwoofers position in the car.
