Data sheet
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 cabinet of the DDQ Sub 18 is made of 18mm thick multiplex with an extremely durable polyurethane finish. It is equipped with two M20 threaded flanges and ergonomic handles and is prepared for mounting of casters.

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.

- Onboard D-XSUB LF processing provides total low-frequency management
- Normal mode: Set for ideally balanced low-frequency response
- Boost mode: Provides a tighter and more focused bass with some extra punch
- Xtended LF mode: Drops the low-end frequencies down even further for a large bottom end
- Cardioid mode:
- Works with two or more subwoofers
- Effectively decreases the sound pressure on stage while increasing the bottom-end output directed towards the audience
- Results in a much cleaner stage monitoring environment
- DSP protection functions for maximum output and component longevity
- Active subwoofers ensure the combination of transducer and amplifier are matched and optimized for the best possible performance
- During development, Yamaha measured and tested the durability of each transducer and the overall amplifier output to set optimal limiter points using precise DSP control
- Employing many of the same protection functions used in high-end professional power amplifiers, Yamaha's DSP consistently monitors the status of the power supply, power amplifiers, transducers, and signal levels to protect each component in order to maintain optimum performance while extending component life and usability

| Add bass
One of the best ways to fill the room with bass with your PA system is by adding a subwoofer. Mackie's Thump 118S powered subwoofer was designed to boost the low-frequency power and output of a PA system using their Thump Series powered speakers, but it'll work with any system that needs more bass. This sub features a built-in amplifier that sends up to 1400 watts to the 18" low-frequency driver in an efficient bandpass enclosure, creating plenty of bass energy for just about any musical application or venue. Internal protection circuits keep the sub rockin' and safely under control, even when the party gets loud and raucous.
Integrates well
Selectable High Pass Modes with a variable crossover setting optimizes the sub for different system configurations and musical genres. A 2-channel input mixer plus 2 full-range and 2 high-pass outputs offer plenty of wiring and integration options. Convenient, top corner handles help ease the pain when carrying this Built-Like-A-Tank™ sub to and from a gig.
