LD Systems LDDDQSUB18 – 18″ ACTIVE PA SUBWOOFER 1400 watt with DSP EOL-DEMO

The LD Systems DDQ Sub 18 is a powerful active subwoofer with digital signal processing for demanding PA applications. It is precisely adapted for combination with the full-range speakers of the DDQ Series and is equally suitable for use with tops made by other manufacturers.

The compact bass-reflex design is loaded with an 18" FaitalPRO bass speaker that has a 4" voice coil and a neodymium magnet driven by two 700-watt Hypex Class D power amplifier modules with a highly efficient switching power supply with a total output of 1400 watts RMS. The DDQ Sub 18 attains a maximum sound-level pressure of 134 dB with a frequency response curve of 30 -120 Hz.

The Sharc DSP programmed especially for the DDQ subwoofers ensures distortion-free and reliable operation even at maximum volume levels with a 1ms look ahead limiter, frequency and phase correction, as well as all protection circuits, and has a large dynamic range of 127dB/113 dB (ADC/DAC). Seven DSP Presets permit selectable crossover frequencies between 80 and 120Hz. Eight additional presets make it possible to realize cardioid configurations of 2 or 3 subwoofers, whereby it is possible to attain rear attenuation of up to 20dB. In addition to XLR inputs and outputs, the DDQ Sub 18 has a separate mono output with a 100Hz high-pass filter. Additional features are LED function indicators and a ground lift switch; the volume and preset controls can be deactivated to prevent inadvertent adjustment.
