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 DXS 18 achieves best in class SPL of up to 136dB and delivers the lowest frequency response (down to 32Hz) in the lineup. Housed in a sturdy band-pass enclosure, the custom built 18” driver with a large 4-inch voice coil and a Class-D amplifier delivers 1020W of power with exceptional clarity and accuracy.
- Powered reflex subwoofer
- Woofer: 18" with 4" voice coil
- Ideal for low-frequency extension to all full-range loudspeakers
- Maximum SPL: 136 dB
- Frequency range (-10 dB): 30 to 150 Hz
- High-power 1600W Class-D amplifier module
- Lightweight yet very durable plywood cabinet with premium grade Polyurea coating
- Optional speaker cover (SPCVR-DXS18X) and wheel kit (SPW-1)
- DXS XLF subwoofers are driven by 96 kHz high-power DSP processors and utilize dynamic EQ
- 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

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. |
