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.

The Avant 118A is a powered rear-loaded horn-bass subwoofer system designed to provide extended bass response for the Avant full-range cabinets.

A 1250 W Class D amplifier drives a D.A.S. 18LX log excursion bass loudspeaker. The 18LX loudspeaker incoporates a 4″ voice coil for high power handling and output.

The Avant 118A incorporates a 1250 W Class D amplifier with switch mode power supply (SMPS) and digital signal processing (DSP).The amplifier has a unique EQ switch which allows the user to select a Deep subbass response or a Loud bass response. The system includes two balanced inputs with stereo filtered output connections for satellite systems. The variable crossover ranges from 100 Hz-160 Hz and can be defeated to offer stereo "loop thru” connections. A gain control and polarity reverse feature increase user control over the system.

Technical Data

DBTechnologies' new subwoofers H Series offer remarkable specifications and user-friendliness. With 1500W (2000W Peak Power) and a high-performance 18' woofer with 8' coil, the Sub 18H is especially suited for small to mid-sized events, where high performance needs to be packaged into compact size.  Thanks to their unique configuration, termed Hybrid Horn-Loading, the boxes can be tuned to the lowest frequencies to improve system efficiency and convey a deep, enveloping sound. Unlike conventional horn loaded systems, 15H and 18H subs ensure excellent efficiency even at close listening distance, which makes them suited for use even in small venues.
