The LD Systems DDQ Sub 212 is a powerful active subwoofer with two specially developed 12″ bass speakers and digital signal processing, specially conceived for use in combination with the full-range speakers of the DDQ Series. It ensures deep bass reproduction in PA systems and can also be matched to the satellites/tops of other manufacturers.
The two woofers with 3″ coils and neodymium magnets are driven by two 700-watt Hypex Class D power amplifier modules with a highly efficient switching power supply and a RMS output of 1400 watts. The DDQ Sub 212 attains a maximum sound-level pressure of 132 dB over a frequency response curve of 38 – 120 Hz.
The Sharc DSP programmed especially for the DDQ subwoofers has a large dynamic range of 127dB/113 dB (ADC/DAC) and handles frequency and phase correction in addition to providing extensive protection functions for reliable operation. Its 1ms look ahead limiter provides for distortion-free reproduction even at maximum volume levels. 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. The inputs and outputs as well as the separate mono output with a 100Hz high-pass filter use Neutrik XLR sockets. Additional features are LED function indicators and a ground lift switch; the volume and preset encoders can be deactivated to prevent inadvertent adjustment.
The compact band-pass enclosure of the DDQ Sub 212 is made of 18mm thick multiplex with an extremely durable polyurethane finish. It is prepared for mounting of casters and features comfortable handles and two M20 threaded flanges.

What is Class-D Technology?
Instead of operating relatively continuously like Class AB circuits, Class-D amps switch on and off thousands of times per second, delivering power only when needed. The amplifier is either fully on or fully off, which significantly reduces power losses from the output devices given off as heat. Less heat means our Class-D amps don't need massive heat sinks, and that means we can make them lighter. Plus B1200D's amplifier provides all the dynamic punch and fidelity you'd expect from a much larger, more expensive subwoofer.
Custom-Designed Transducers
The transducers (woofers and tweeters) are the only part of a sound system you actually hear, so we never cut corners, and we never just grab whatever happens to be on the shelf. We custom-design our own so they are the perfect match for both the amplifier and the application. We wind our own voice coils, process the paper pulp into cones and even machine our own backplates. This enables us to control the quality, and frankly, make better components. The 12" long-excursion, low-frequency transducer was designed specifically for use in the EUROLIVE B1200D.
Take Control
The B1200D features balanced XLR inputs and outputs, as well as balanced XLR Thru jacks for connecting additional enclosures. A Boost Frequency knob lets you boost any frequency between 45 Hz and 90 Hz. Then just flick the Boost switch to give your selected frequency a +10 dB boost. We've also provided a High Cut dial that controls the upper-corner frequency for the internal amplifier without affecting Thru A/B signals. A Level knob controls the input gain, and the Phase switch reverses the output phase to compensate for frequency cancellation between the subwoofer and satellite speakers. LEDs show operational status at a glance including power, signal present and input overloads.

The KSub is a dual-12" bandpass design, constructed of premium birch and includes high-quality, low-noise casters. The subwoofer features a threaded pole receptacle for a positive, wobble free connection to a threaded speaker pole (included).
Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Euroblock connector. In an installed application, multiple K Series speakers can be "daisy-chained" for total gain control from a single remote pot. Auto-standby mode is engaged after 5 minutes of inactivity.
Extensive DSP
DMT™ (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.
Intrinsic Correction™, first featured in our high-end line-array products maps 65-75 spacially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass target. The result is a speaker that behaves equally well across the entire sound field.
DEEP™ and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.
GuardRail™ protection, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.
