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 MILAN M18 is a self-powered bandpass subwoofer enclosure consisting of an 18" low frequency driver housed in an optimally tuned enclosure, together with an integrated lightweight 1kW Class D amplifier.

The amplifier provides two input channels with balanced jack/XLR connectors, and two link outputs on male XLRs, providing connections to further Milan mid-high cabinets or subwoofers. A filtered high-pass output also provides connections to other mid-high cabinets. The left and right signals are summed in the subwoofer through a low-pass filter to the 18" driver. A sub level control is provided in order to achieve an even level between the subwoofer and Milan mid-high cabinets. The M18 is available in two versions to suit regional AC mains voltages of either 110 volts or 230 volts, and mains power is supplied via an IEC mains connector.

The Class D amplifier features sophisticated signal processing which provides limiting functions to ensure high performance and long term reliability. Status LEDs indicate mains power, signal present and signal limit. The cabinet is constructed from 15mm laminated plywood and is finished in dark blue textured paint. A pole mount socket is fitted to allow Milan M15 cabinets to be mounted on optional 35mm speaker poles.

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.
